MULTI-ROOM SYSTEM CONTROLLER RMZ-955  
Getting Started  
Component Description  
The Rotel RMZ-955 Multi-Room Control System distributes audio  
signals from a single set of source components to as many as  
four separately controlled remote zones or listening areas. The  
centrally located RMZ-955 controller/amplifier contains source  
selection, microprocessor controlled communications circuitry  
and independent preamplifier/power amplifiers for all zones.

I.R. TRANSMITTER  
Users can select either of two ways to control remote zone op-  
eration. The first is the RR-952 hand held remote. This generates  
infrared (IR) control pulses read by the wall-mounted RSM-901  
sensor/display. The RSM-901 sensor/display then transmits com-  
mands to the RMZ-955 through hard-wired connections.  
The RMZ-955 Controller/Amplifier is the heart of the RMZ-955  
Multi-Room Control System, featuring:  
The second method uses the wall-mounted RKP-901 keypad to  
transmit commands directly to the RMZ-955. The RKP-901 is also  
hard-wired to the RMZ-955 controller/amplifier.  
• Four separate microprocessor-controlled stereo preamplifier/  
power amplifier sections, one for each remote zone  
• RCA inputs for up to four sources  
Users can select a combination of sensor and keypad operation  
for any zone. The system accepts inputs from up to three sensor/  
displays and three keypads (for a total of six input devices) per  
zone.  
• “Loop through” RCA outputs which allow multiple RMZ-955 con-  
trollers to be linked together for large systems up to 16 zones.  
• RCA line level preamp outputs for use with external amplifier  
systems. These outputs can be internally configured to provide a  
variable level signal or a fixed level signal.  
System Flexibility  
The Rotel RMZ-955 Multi-Room Control System is exceptionally  
flexible. In addition to the RMZ-955 controller/amplifier, a simple  
two zone system might include just one RR-952 hand held con-  
troller/RSM-901 IR sensor/display combination for one zone and  
one RKP-901 keypad in the second.  
• Screw-type quick connect speaker outputs  
• Control data input for each zone is via industry-standard 6 pin  
Methode connectors  
In a more elaborate configuration, a single RMZ-955 accepts  
commands from four separate zones via twelve IR sensor/dis-  
plays and twelve keypads.  
• 3.5 mm stereo jack “AC Link” connections for full system control  
from any zone in large, multi-controller systems  
• RCA output jack for RC-5 remote control protocol components  
Up to four RMZ-955 controllers can be linked together for a sys-  
tem with as many as sixteen independent zones.  
• High power front panel IR flood emitter to transmit remote zone  
commands to associated source components  
System Highlights  
• Four mini-plug IR repeater outputs  
• Keypad or handheld remote operation of source components. No  
programming required – built-in codes for Rotel and other popu-  
lar components.  
• Two polarized AC convenience outlets with 100 watts capacity  
each: one switched to allow easy remote control of total system  
power if desired, the other unswitched  
• Single button operation for source selection and “play”.  
• Full user control, including system standby from any zone.  
• Built-in Paging input with muting in selected zones.  
• Front panel LED indicators for Power On/Off, zone status, com-  
mand pulse processing  
• Near-universal Infra-red repeating system. Remote control avail-  
able even when a zone is not active.  
System Planning  
• Alarm clock function with independent wake-up in each zone.  
The RMZ-955 is designed to be used as a stand-alone control  
center for a multi-zone distribution system using dedicated  
source components. It features loop-through source connec-

GETTING STARTED  
You’ll find details of the display in the Set Up and Operation sec-  
tions of this manual.  
RR-952 IR Remote Control  
NOTE: An RSM-901 connected to the Zone A data input MUST be  
used during initial set-up.  
RKP-901 Keypad  
The RR-952 infrared remote control serves a dual purpose. In ad-  
dition to providing dedicated pushbuttons for the most needed  
functions of both the RMZ-955 controller/amplifier and source  
components, it also serves as a quick set-up tool during initial  
configuration.  
The RKP-901 is a wall-mounted keypad for convenient remote  
operation of the entire system. The keypad can be used as a  
stand-alone control device, although it is most functional when  
installed with the RSM-901 sensor-display. Its 12 key design is  
the optimum balance between flexibility and simplicity, providing  
single-key control of the system and source components (select-  
ing and starting a CD player, for example). In addition, the  
RKP-901 allows total system shut-down from a remote location. It  
mounts conveniently in a standard single width wall box or in a  
dual width box with a RSM-901 sensor/display. (see page 25)  
The RR-952 has a special high intensity IR transmitter. In con-  
junction with the system’s sensitive receiver modules, this trans-  
mitter assures reliable operation under a wide variety of  
conditions.  
RSM-901 Sensor/Display  
RSM-901/RKP-901 Combination  
Mounting both the sensor/display and keypad in one double-  
width wall box carries several advantages. It simplifies the in-  
stallation. It also focuses the user on one location in each zone,  
i.e. walk to the keypad or aim the hand held remote control at the  
same wall-plate.  
The wall-mounted RSM-901 Sensor/Display receives commands  
from the RR-952 hand held remote and, after processing to en-  
sure maximum data integrity, sends these codes to the RMZ-955  
controller/amplifier.  
In addition, the RSM-901 provides continuous system status in-  
formation (source, time, volume setting, etc.) at each remote lo-  
cation with a dot matrix display. Also available is a  
programmable alarm function.

Placement  
Place the RMZ-955 on a stable surface in an equipment rack or  
cabinet. Note that the RMZ-955 is slightly deeper than most  
source components (tuners, CD players, cassette decks, etc.)  
and should not generally be placed on top of these units.

Connections:  
RMZ-955 controller  
Make sure that you have enough room to run all the connecting  
cables and dress them appropriately behind the RMZ-955. Al-  
though we’ll explain each connection fully in following sections  
of this manual, glance through the following list of possible con-  
nections and decide how much space you’ll need.  
Keep total IR signal travel to 40' or less. Remember that it  
must travel to a hard reflective surface and back again.  
a) Four pair of RCA interconnects – one pair from each source.  
b) Eight heavy gauge speaker cables (two for each zone).  
Note: If an RSM-901 sensor display is located in the same room  
as the RMZ-955 controller, it is essential that the output form the  
front-panel IR flood emitter NOT reach the RSM-901 sensor. IR  
loop problems can cause intermittent operation.  
c) Four six-conductor + shield data cables, each terminated with  
the proper IDC strip connector.  
d) One shielded RCA to RCA interconnect for RC-5 remote control  
code connection.  
IR Repeater Jacks  
The RMZ-955 also has four rear panel IR output jacks for use  
with industry standard IR repeaters (made by Xantech and oth-  
ers). The use of these external repeaters on each source compo-  
nent is ideal in situations where output from the front panel flood  
IR emitter is blocked from the source components by a door, full  
depth shelf, etc. It is also an ideal solution when the front panel  
flood emitter output could reach an RSM-901. When IR repeaters  
are used, the front-panel flood emitter can be easily disabled.  
e) One pair of RCA to RCA interconnects to power amplifiers from  
each corresponding zone’s “Pre-out” terminals.  
f) Up to four mini-plug (3.5 mm) cables from the RMZ-955s Infra  
Red” outputs to remote IR transmitters.  
g) Four more pair of RCA to RCA interconnect cables – one each to  
the appropriate input of the next RMZ-955 in large multi-control-  
ler systems.  
h) Additional loudspeaker connections as required for systems us-  
ing more than one RMZ-955 controller/amplifier.  
System Wiring Considerations  
i) 3.5 mm to 3.5 mm cable for AC “link” connections as required for  
systems using more than one RMZ-955 controller/amplifier.  
Data Cable and Connectors  
The data path between the RMZ-955 controller/amplifier and  
RSM-901 sensor/displays and RKP-901 keypads must be made  
with cable with six insulated conductors plus a foil and/or  
braided outer shield. We recommend a Belden 9536 equivalent  
for best results. The RMZ-955 system data connectors work only  
with cables using 24 gauge conductors. Make sure that all data  
cables conform to this requirement.  
j) Up to six “TX-FORM” terminal block jumper wires needed when  
cascading multiple RMZ-955 controller/amplifiers.  
We STRONGLY RECOMMEND that you attach a tag or strip to  
each cable and wire to identify it (e.g. “To Input 3 from tape  
deck.”). This will help in troubleshooting as well as make future  
service calls or system add-ons much less frustrating.  
Data cable termination is via industry-standard 6 pin IDC  
connectors made by Methode and others. (The Methode part  
number is 1300-106-424.) Data cable connection instructions are  
found in the Installation section of this manual (see page 9).  
IR Flood Emitter  
The RMZ-955 has a high intensity front panel IR flood emitter de-  
signed to transmit commands from the remote zones to the ap-  
propriate source component. Although exact performance will  
vary, this high power transmitter has an effective operating  
range of approximately 40' under normal conditions.

Unshielded two conductor 18 gauge  
(AWG) speaker wire is the minimum  
acceptable standard for connections  
between the RMZ-955 controller/

MULTI-ROOM SYSTEM CONTROLLER RMZ-955  
The switched outlet provides the mechanism for “powering up”  
Installation: RMZ-955 Controller  
or “powering down” all of the source components from the re-  
mote zones. We recommend plugging the AC power cords from  
the source components into the switched outlet on the back of  
the RMZ-955.  
This section covers all hardware installation and configuration  
issues related to the RMZ-955 controller, including wiring con-  
nections for AC power, source connections, speaker connec-  
tions, pre-amp connections, data cable connections to the  
remote zones, Infrared control connections, and special features  
such as the paging feature. The next section of the manual (see  
page 12) covers similar topics related to the installation, wiring,  
and hardware configuration of the zone control devices – the  
RSM-901 Sensor/Display and the RKP-901 Keypad.  
Rotel RLC-900 AC line conditioner/switcher  
We strongly recommend the use of the RLC-900 AC line condi-  
tioner/switcher to improve both the performance and convenient  
operation of all system components. The RLC-900s benefits in-  
clude increased protection from AC power line surges and im-  
proved system AC power management for proper turn-on and  
turn-off sequences.  
For the sake of simplicity, these two sections cover the installa-  
tion of a basic 4-zone system with a single RMZ-955 controller,  
since this is the most typical system configuration. There is a  
separate section Installation: Multi-controller Systems (page 15)  
that covers installation, wiring, and configuration topics related  
to larger, more complex systems with multiple RMZ-955 control-  
lers.  
To incorporate the RLC-900, follow these steps:  
a) Plug all system source components into the RLC-900’s “Digital  
Equipment” or “Accessories” outlets as appropriate.  
b) Plug the RMZ-955’s AC power cord into the RLC-900’s  
“UNSWITCHED” outlet.  
c) Plug the RLC-900’s “Control Cord” into the RMZ-955s SWITCHED  
AC Line Connections  
outlet.  
d) Plug the RLC-900’s “Main Power” cord into an unswitched AC  
AC for the RMZ-955  
outlet such as a wall receptacle, etc.  
Plug the RMZ-955 controller/amplifier into an unswitched AC  
source only, i.e. a wall outlet. It is essential for proper system op-  
eration that the RMZ-955 be plugged into a constant source of  
AC power, since it has “stand-by” circuitry that must receive  
power for full control from any zone at any time.  
When a system activation command is sent from a remote zone, the  
RLC-900 turns on all source components automatically.  
Special AC features  
We recommend a powerline filter as the RMZ-955 contains a  
number of microprocessor ICs that may benefit from the extra  
protection afforded by a quality filter/surge protector.  
Some source components power up in a standby mode when AC  
power from a switched outlet turns them on. These components  
require a separate command to fully activate them. The RMZ-955  
has a built-in software function, called “power toggle” that can  
handle this “power up” sequence, if necessary. This feature is  
fully described in the System Set-up & Programming section of  
this manual on page 22.  
AC for Source Components  
The RMZ-955 has two rear panel AC convenience outlets, one  
switched and the other unswitched. These may be used to sup-  
ply power for components used with the RMZ-955. Each outlet  
carries a maximum load rating of 100 watts.  
Unswitched AC outlet: The RMZ-955s Unswitched AC outlet  
supplies AC current whenever the RMZ-955 is plugged into a live  
AC source. This outlet is NOT controlled by the setting of the  
RMZ-955’s front panel power switch.  
Switched AC outlet: This outlet provides a mechanism for con-  
trolling AC power to other components, such as source compo-  
nents. When the RMZ-955’s front panel switch is Off, the  
switched AC outlet is also off. Even when the front panel switch  
is turned On (i.e., when the RMZ-955 first powers up to  
“Standby” mode), the switched outlet remains off until the  
RMZ-955 receives a zone activation command from one of the  
remote zones. The switched AC outlet then remains on until the  
front panel power switch is turned Off or the RMZ-955 receives a  
“system shutdown” command from a remote zone.

INSTALLATION: RMZ-955 CONTROLLER  
Note 1: The RMZ-955 does not accept a phono cartridge’s output  
directly. If required, use a separate phono preamp (such as  
Rotel’s RQ-970BX) to boost phono signal to line level.  
Source connections  
The RMZ-955 has four pair of RCA inputs for four source compo-  
nents, as well as four pair of RCA “loop-through” outputs that  
can send the source signals to other components.  
Note 2: Use only FIXED LEVEL source outputs to the RMZ-955.  
Source outputs  
Source inputs  
Each source input on the RMZ-955 has a matching pair of “loop-  
through” output RCA jacks. The primary use of these “loop-  
through” outputs is to pass the signal from each source  
component to additional RMZ-955 controllers in large multi-zone  
systems (see page 15 for details on installing large systems).  
Connect LINE LEVEL sources (CD player, tuner, etc.) to the  
RMZ-955’s rear panel inputs as follows.  
Using shielded RCA-RCA cables, connect the source’s output to  
the corresponding source input on the RMZ-955. Connect analog  
outputs from the source components as indicated to assure  
clear operation with both the RR-952 hand held remote and the  
RKP-901 keypad:  
In some cases, these “loop-through” outputs may alternatively  
be used to “share” the source components with a separate  
home theater or audio system. If the source is shared by another  
system, connect each pair of RMZ-955 source outputs to the  
appropriate inputs of the main system’s preamplifier as shown in  
the hook-up illustration.

Note: The source sharing does not work with all combinations of  
components. Specifically, home theater and audio systems with  
micro-processor controlled source input switching may result in  
problems such as interference or “mixing” between shared  
sources.  
Make sure to observe correct channel continuity from source to  
RMZ-955. The RMZ-955’s RCA inputs are labelled for easy identi-  
fication with Left Channel connections on the top row and Right  
Channel connections on the bottom row.

Strip back each speaker wire’s insulation by 1/4 inch. Insert the  
bare wire into one “slot” on the quick-connect plug and secure  
by tightening the corresponding clamping screw. Repeat for the  
other conductor, making sure that there are no loose strands of  
wire which could cause a short. Repeat for the second speaker  
in zone one and then continue with the other zones.

Remember to observe proper polarity when connecting all loud-  
speakers. The amplifier’s “+” output should connect to the  
proper speaker’s “+” terminal. “Out of phase” loudspeaker hook-  
ups (where one speaker in a stereo pair is inadvertently con-  
nected “+” to “-” and vice versa) may not be immediately  
noticeable but will not be as pleasing as a properly connected  
stereo pair. BE CAREFUL AND BE PATIENT.

INSTALLATION: RMZ-955 CONTROLLER  
The long runs from amplifier to speaker typically found in multi-  
zone installations demand heavy gauge, low resistance speaker  
wire. Small diameter wire reduces effective amplifier power and  
adds substantial distortion to the audio signal. Avoid problems by  
following these minimum recommendations:

Each zone’s preamp output is fully buffered and may be used ei-  
ther independently or along with the RMZ-955’s internal amplifi-  
ers to provide additional flexibility for demanding installations.  
Factory default:  
variable level  
pre-amp output  
For fixed-level line-driver  
output, remove module,  
rotate 180° and reinstall  
using other set of pins.  
If a zone requires additional amplification, use standard RCA-  
RCA shielded interconnects from these outputs to a separate  
power amplifier’s unbalanced line inputs as shown in the hook-  
up illustration on the preceding page. Connect the left channel  
“Pre-out” jack to the left channel input on the power amplifier  
for that zone; then repeat for the right channel connections.  
Note that the side of the module with the actual electronic com-  
ponents remains facing to the left side of the RMZ-955, regard-  
less of which set of header pins you use. Also note that the pins  
and the socket are labeled 1 — 15. Pin 1 is always inserted into  
Socket 1, etc.  
Note You can configure each of the four zones independently, by  
rotating just its module. Some zones can be configured as vari-  
able outputs, while others are reconfigured as fixed outputs by  
reorienting some or all of the modules.  
Variable vs. Fixed Level  
As delivered, the preamp outputs are configured to provide a  
variable level output, i.e. the volume level of the signal can be  
adjusted with a volume control in each zone. Alternatively, the  
pre-amp outputs for one or more zones can be converted to pro-  
vide a fixed level line drive signal, i.e. a signal that is always at a  
fixed gain (0.25dBV below that of the source component). This  
may be useful in certain custom applications.  
Converting the pre-amp outputs to fixed level operation requires  
removing the top cover of the RMZ-955 and locating the four  
“line driver” plug-in modules. Looking from the front of the unit,  
these are small vertical circuit boards located in front of the heat  
sink. They are labeled Zone A through Zone D, from left to right.  
Notice that the modules are printed circuit boards that plug into  
the main board. Each module has two rows of “pins”, one on the  
bottom (which is plugged into a socket as delivered from the fac-  
tory) and the other pointing up. To reconfigure from variable level  
pre-amp outputs to fixed level pre-amp outputs, simply remove  
the module from the socket on the main circuit board, rotate it  
180 degrees, and reinsert it in the same socket using the row of  
pins on the opposite end.

MULTI-ROOM SYSTEM CONTROLLER RMZ-955  
The supplied Methode connectors need to be crimped to lock to  
the data cable’s 24 gauge conductors.  
Data cable connections  
Note: Do not use a screwdriver, metal ruler or knife blade to  
“crimp” these connections. You may think these tools will work  
but you will be mistaken. USE THE DEDICATED CRIMPING TOOL  
SPECIFICALLY DESIGNED FOR THESE CONNECTORS. This tool is  
available from Rotel.  
Data communication to and from the RMZ-955 controller and the  
remote zones’ RSM-901 sensor/displays and RKP-901 keypads is  
by 6 conductor shielded cable.  
Note: One, and only one, data cable runs from the RMZ-955 to  
each zone. Multiple sensor/display and keypad combinations in  
one zone should be wired via series connections detailed in the  
section on Zone Connection Strategies (page 15).  
• Strip about 1.5" of the outer cable insulation using a sharp knife.  
Separate the outer shield from the conductors and trim it off  
flush with the outer insulation, being careful not to trim off the  
shield or “drain” wire.  
We recommend the use of Belden 9536 cable or the equivalent.  
The Methode data connectors supplied with the RMZ-955 only  
accept cable with 24 gauge conductors.  
• DO NOT strip insulation off the six individual conductors as the  
connector automatically makes contact with the conductor core  
when crimped.  
Using cable with a foil and/or braided shield is absolutely essen-  
tial in maintaining data integrity over the long runs between the  
controller/amplifier and a zone’s control code generating de-  
vices. Make sure that the shield is firmly connected at both the  
RMZ-955 and at any command device terminal.  
• Place the shield or “drain” wire into slot 1 of the connector.  
Then, place the BLACK conductor immediately on top of the  
drain wire in slot 1, hold them both in place and push the crimp-  
ing tool handle until you hear a slight “click.” Both conductors  
should now be locked into slot 1. The rachet action of the crimp-  
ing tool ensures proper connection. The clicking sound tells you  
that the connector slot contacts have pierced the conductor’s  
insulation.  
We recommend that you run each zones data cable and speaker  
cables together to save time. There is absolutely no performance  
penalty for doing so.  
PROPER DATA CABLE TERMINATION IS CRITICAL. All connec-  
tions for RMZ-955 and the remote zone’s RSM-901 sensor/dis-  
plays and RKP-901 keypads use the color code shown in the  
following illustration:  
• Continue the process following the color code guide above until  
all other conductors are locked in the appropriate connector  
slots. Remember that slot 1 is the ONLY ONE to get the drain  
wire and a conductor. All other slots receive only a conductor.  
After attaching the cable conductors to the connector, insert it  
into the appropriate zones 6 pin data terminal on the RMZ-955’s  
rear panel. Be careful to center the connector over the terminal  
pins before inserting.

To disable the IR flood emitter, remove the jumper wire between  
screws 2 and 3 of the TX FORMAT terminal block located on the  
lower right hand side of the RMZ-955’s rear panel.  
Infrared Control System  
The RMZ-955s IR system provides extensive control flexibility  
accepting remote control codes generated by keypads and/or  
hand-held remotes, relaying them to the system controller, and  
passing them along to the source components via a front-panel  
flood emitter or individual remote IR emitters plugged into the  
rear panel. However, please note the following points:  
Optional remote IR emitters  
for use in place of front panel  
IR flood emitter. One required  
for each source component.

The IR codes generated by the RR-952 hand held remote are  
RMZ-955 “system specific” codes and ARE NOT the same codes  
generated by a source component’s own controller, even for  
functions that appear identical such as “CD play,” for example.  
In other words, you can not use the RR-952 to directly control a  
Rotel CD player but must use it through an RSM-901 sensor/dis-  
play from a remote zone.

The RMZ-955 IR control system does the following:  
• An RSM-901 sensor/display receives the remote’s code se-  
quence and translates it into proprietary 5 bit digital code.  
Remove this jumper to disable front  
panel IR flood emitter.  
• This digital code travels over the data cable to the RMZ-955  
controller/amplifier.  
NOTE: There is a very low intensity red LED mounted behind the  
emitter’s window which flashes whenever it is transmitting IR  
codes. Use this LED to verify the emitter’s operating status.  
• The RMZ-955s translator card restores the code’s original con-  
figuration (when required) and sends it to both the IR flood emit-  
ter and the rear panel IR outputs for use by the appropriate  
source component.  
Rear Panel IR Repeaters  
In addition to passing RMZ-955 system codes, the IR system will  
pass ALMOST any IR code sequence from an RSM-901 to a  
source component. (These few exceptions use a non-standard  
IR transmission frequency.) This allows you to control transport  
functions of a VCR from a remote zone, for example, with the  
VCR’s dedicated hand held remote.  
In many system configurations, the most reliable, trouble-free  
means of passing IR control codes to the source components is  
with individual IR emitters, one for each source. Use these op-  
tional repeaters in situations where the RMZ-955 will be located  
some distance away from the source components or where the  
IR flood emitter may have difficulty transmitting reliable source  
control data. Disable the flood emitter when using the optional IR  
remote emitters.  
Front Panel IR Flood Emitter  
The RMZ-955 features a front-panel flood emitter for sending IR  
codes to the source components own front-panel IR sensors.  
The RMZ-955 rear panel has four paralleled 3.5mm mini-plug  
sockets labeled “TX OUTPUTS.” They accept standard “stick on”  
IR emitter like Xantech’s Video Link 282-00. Plug a repeater into  
one of the sockets and place it over the source component’s IR  
sensor. Repeat for the other three sources.  
Note: It is essential that the output of the front-panel flood emit-  
ter NOT be allowed to reach an RSM-901 sensor/display. This  
could result in an IR loop and unstable system operation includ-  
ing “lock-up”  
Note: Some source components, such as some Rotel sources, al-  
low a direct connection from a 3.5 mm rear panel IR emitter con-  
nection to a matching 3.5 mm connection on the source  
component, eliminating the need for stick-on IR emitters.  
RMZ-955s are shipped with the front panel IR flood emitter en-  
gaged. However, there may be applications (system installations  
on open shelves in very large, bright rooms, for example) where  
the IR flood emitter might interfere with proper source compo-  
nent operation or will not be particularly effective in communi-  
cating control pulses. Or, there may be systems where an  
RSM-901 display/sensor located in the same room as the RMZ-  
955. In these cases, disable the front-panel flood emitter and use  
individual IR emitters connected the RMZ-955’s rear panel and  
placed over each source components IR sensor.

Paging Inhibit  
Paging Input  
The paging function is individually configurable for each zone.  
The installer can select which Zones will receive or not receive  
an announcement when the paging is activated. Each Zone has  
an internal micro switch which is used to set the paging function  
ON/OFF for that zone. These switches are accessed by removing  
the top cover of the RMZ-955 by a qualified technician. Make  
sure that the AC power line is disconnected before removing  
the cover.  
The paging input allows announcements to be made over the  
system, and, if required, for Zones to be momentarily muted, in  
conjunction with a doorbell or a phone system.  
The paging feature needs to be activated from an external  
source via the “paging trigger” RCA-type input jack on the back  
of the RMZ-955. Any device which shorts the trigger input will  
cause the controller to enter its paging mode. For example, a  
doorbell, a phone system , or a keyed announcement micro-  
phone system could provide this control.  
RMZ-955 Circuit Board  
back  
The “Paging Audio In” RCA jack is connected to the audio output  
of the announcement system (phone or microphone amplifier).  
The “Paging Audio Output” jack can be connected to the Paging  
Audio Input on a second controller (in a large multi-controller  
system) or to the RCA input of an external amplifier.

PLACEMENT SUGGESTIONS: Exact placement will vary with  
each installation but we strongly recommend AGAINST place-  
ment where the RSM-901 will be exposed to direct sunlight, pow-  
erful fluorescent illumination or the output of a high intensity  
spotlight, etc. These light sources contain high levels of infrared  
energy themselves and may cause intermittent operation by

Master/Slave Configuration  
Each RSM-901 must be configured as a Master or Slave by set-  
ting Switch 6. Because it is possible to have more than one

required functions are available:  
The “In” connector is used to “daisy-chain” additional RSM-901  
display/sensors or RKP-901 keypads in the same zone. See Zone  
Connection Strategies on page 15 for details.  
Each zone used in a system must have a Master RSM-901. In a  
zone with more than one RSM-901, only one must be set as a  
Master and each other must be set as a Slave. The Master must  
be the first device on the data cable to the zone from the  
RMZ-955.  
A number of configuration settings must be made using the  
switches and jumpers on the back of the RSM-901. These are de-  
tailed below.  
Battery Enable  
The Master/Slave settings for Switch 6 are:  
Each RSM-901 has a rechargeable back-up battery which main-

Note: After completing the installation and component set-up,  
power down the system, wait approximately 30 seconds, and  
then power it up again. Test all functions.  
RKP-901 Data Connections  
RKP-901s do not need to be set for particular zones or configured  
as Master/Slaves because they do not display zone or system

nience should be the determining factors. Alternatively, the  
RKP-901 can be mounted in a double-width wall box with an  
RSM-901 sensor/display. This is the most sensible arrangement  
from an installation viewpoint (fewer cable runs) but may not be  
practical in all rooms.

MULTI-ROOM SYSTEM CONTROLLER RMZ-955  
Installation: Multi-controller Systems  
Zone Connection Strategies  
Each RMZ-955 provides independently controlled audio distribu-  
tion from four sources to four separate zones. To satisfy the re-  
quirements of more elaborate systems, up to four RMZ-955s can  
be cascaded to build a system with as many as 16 independent  
zones. Under these circumstances, all RMZ-955 controller/ampli-  
fiers share one set of four source components.  
Each zone will support up to three RSM-901s and three  
RKP-901s. All of the command devices for one zone should con-  
nect to each other in serial fashion using their appropriate cir-  
cuit board-mounted “In” and “Out” terminals.  
Each RSM-901 signals when it receives and processes a com-  
mand. This happens regardless of whether the command was  
generated by a keypad or a hand held remote. However, a key-  
pad located “downstream” of a sensor/display will not trigger  
that sensors command processing indicator.  
When system complexity calls for more than one RMZ-955, we  
have no cautions about stacking controller/amplifiers on top of  
each other. As long as there is sufficient room to allow relatively  
unrestricted air flow, heat should not be a problem.  
Whenever possible, we suggest that you configure each zone so  
that all keypads are “upstream” from all sensor/displays. Al-  
though not always practical depending on the zone configura-  
tion, this arrangement will reduce user confusion.  
In most respects, installing a multi-controller system is no differ-  
ent than a single controller system. Source input connections,  
speaker output connections, data cable connections to the re-  
mote zones, and other configuration steps are essentially the  
same. Review Installation: RMZ-955 Controller (page 5) for com-  
plete information.  
Regardless of other considerations, we suggest that you always  
wire an RSM/RKP double wall box so that the RSM is located  
“downstream” from adjacent RKP (i.e., between the RKP and the  
RMZ-955 controller/amplifier). This assures that the sensor/dis-  
play always signals the user when the adjacent keypad is used.  
There are, however, some additional considerations and installa-  
tion steps required for a system with multiple RMZ-955 control-  
lers. These steps all deal with the need to link the controllers:  
Installation is the first step towards enjoying an RMZ-955 system.  
Proper set-up ensures that the RMZ-955 will function optimally  
with all associated source components and provide total system  
control.  
a) AC connections for fully-integrated system control  
b) Sharing four sources among all controllers  
c) Passing IR commands from one controller to the rest  
d) Linking special features like system-wide paging  
All hookup instructions in this section assume that Zones 1-4  
will be handled by the first RMZ-955 (called “A”), Zones 5-8 by  
the RMZ-955 immediately above it (“B”), Zones 9-12 by third  
unit (“C”), and Zones 13-16 by the top unit (“D”). In most cases,  
we do not illustrate all four controllers, as additional controllers  
are merely added in the same fashion as the second or third con-  
troller.  
There is no functional distinction between the first RMZ-955 and  
additional controllers in a system. However, for convenience and  
simplicity, we assume that the first controller will handle some  
additional responsibilities, such as source inputs and sending IR  
signals to the sources. This approach makes it easy on the in-  
staller, particularly when starting with a single RMZ-955 and later  
expanding with additional controllers. Essentially, the work done  
installing a single RMZ-955 remains unchanged and additional  
zones are handled by “add-on” RMZ-955 controllers.

MULTI-ROOM SYSTEM CONTROLLER RMZ-955  
“power down” command is given from any zone, the RMZ-955  
controllers go into Standby mode, the rear panel switched AC  
outlets are shut off, and this control signal goes to 0V.  
AC Power  
Multiple controller systems require handling AC connections in a  
way that allows any zone to “power up” or “power down” the  
system. In other words, there must be a provision for zones con-  
nected to additional RMZ-955 controllers to control the systems  
switched AC outlets.  
This external trigger requires the same 3.5 mm stereo mini-jack  
as the “AC Link” connections. The “tip” of the connector carries  
the +5V DC control voltage.  
Manual AC Override  
A special feature of the RMZ-955, called “AC Link” simplifies the  
installation of multi-controller systems with a simple control line  
connection between units for AC control.  
There is a provision to manually override the “AC Link” control of  
the switched outlets. While not common, there may be custom  
system configurations where being able to manually power up all  
of the switched outlets and components connected to them.  
AC Connections  
To enable the manual override, connect Pin 1 and Pin 6 of the  
rear panel TX FORMAT jumper block with a jumper wire. As long  
as these two pins are connected, the switched AC outlets on all  
RMZ-955’s will be powered on. When the two pins are uncon-  
nected, control of the AC outlets will revert to standard control  
from the zones, depending on whether the system has been acti-  
vated from a zone or not.  
Plug all RMZ-955 controllers into unswitched AC outlets, provid-  
ing a constant AC supply.  
Plug all source components into the switched outlets located on  
the rear panels of the RMZ-955 controllers. As in a single-con-  
troller system, the recommended approach is to use a Rotel RLC-  
900 power conditioner/switcher in conjunction with the first  
RMZ-955’s rear panel outlets. This allows the first RMZ-955 to  
handle all AC switching for the system.  
In practice, the manual override jumper described above would  
be replaced with a simple single-pole switch connected be-  
tween Pin 1 and Pin 6 of the “TX-FORM” block. When the switch  
is closed, manual override is active. When the switch is open,  
activation of the AC outlets reverts to standard zone control.  
With the “AC Linking” feature, it is also possible to plug source  
components into any switched outlet on the rear panel of any  
RMZ-955. All of these outlets are controlled in unison. When the  
system is “powered up” from any zone, the switched outlets on  
the first RMZ-955 and all other controllers are turned on. When a  
“power down” command is sent, all RMZ-955s go into standby  
and their rear panel switched outlets are turned off.

AC Link  
Unified AC control in multi-controller systems is achieved by a  
special “AC Link” connection from the first RMZ-955 to the sec-  
ond and so on down the line. This connection uses standard 3.5  
mm stereo mini-jacks at both ends of a 3-conductor cable.  
To manually turn on all  
switched AC outlets, connect  
pins 1 & 6 with a jumper  
or closed switch  
For automatic system  
control of switched AC  
outlets, remove jumper  
or open switch  
Note: It is essential to use a stereo mini-jack for the “AC Link”  
connection between controllers (such as Radio Shack #274-389).  
Do not substitute a mono 2-conductor cable.  
Note: In multi-controller systems, Pin 6 must be connected from  
the first controller to the Pin 6 on the next, and so on daisy-  
chainging all RMZ-955s to enable the manual override.  
To make the connection, plug one end of the 3.5 mm stereo cable  
into the 3.5 mm jack labeled “Link Out” on the first RMZ-955.  
Then plug the other end of the cable into the jack labeled “Link  
In” on the second RMZ-955. Then link the second RMZ-955 by  
connecting its “Link Out” to the third RMZ-955s Link In” jack  
with another cable. And, so on until there is an “AC Link” con-  
nection between all RMZ-955 controllers.  
Source Connections  
Multi-controller systems share the same four source compo-  
nents. Therefore, it is necessary to pass the signal from each  
source to all of the RMZ-955 controllers in a system.  
External 5V Trigger: Once you have completed all of the “AC  
Link” connections, the “Link Out” connector on the last RMZ-955  
is still available. This jack can provide a +5V D.C. control voltage  
that could be used to activate external devices in an elaborate  
custom system. When the Rotel system is activated from any  
zone, this control signal goes to +5V. When the total system  
Connect all sources to the first RMZ-955 per the instructions as

INSTALLATION: MULTI-CONTROLLER SYSTEMS  
Then, using standard shielded RCA-RCA audio interconnet  
cables, connect Source 1’s “loop through” outputs on the first  
RMZ-955 “A” to the corresponding Source 1 inputs on the sec-  
ond RMZ-955 “B”. Repeat this procedure for all four sources.  
Use the following connections for multiple RMZ-955 systems:  
For 2 RMZ-955s (5 to 8 zones):  
• Remove the jumper between terminals 2 & 3 of the TX FORMAT  
block on RMZ-955 “B” to disable its IR flood emitter. Leave the  
jumper in place on RMZ-955 “A” if you are using its front-panel flood  
emitter. Remove the jumper if you are using remote IR emiiters con-  
nected to the back panel of RMZ-955 “A”.  
If a system requires a third RMZ-955, repeat this procedure but,  
this time, connect the “loop-though” source output on the sec-  
ond RMZ-955 “B” to the corresponding input on the third  
RMZ-955 “C” and so for a fourth controller “D”.  
• Link IR signals to the first controller by connecting terminal 3 of  
the RMZ-955 “B” TX FORMAT block to terminal 4 on RMZ-955  
“A”. This completes the IR signal link to the IR flood or “remote”  
emitter on RMZ-955 “A”.  
NOTE: It is important to observe proper channel continuity when  
connecting source components to more than one RMZ-955.

Systems with multiple RMZ-955 controllers follow generally the  
same approach to distributing IR signals to the source compo-  
nents as a single RMZ-955 system. Therefore, review the section  
on IR installation, particularly on the choice of using the front-  
panel flood emitter or the back-panel “remote” emitter connec-  
tions.  
Use this jumper arrangement with 3 RMZ-955 controllers.  
Disables the IR flood emitters on all but the first controller.  
Remove gray jumper if using back panel IR repeaters  
from the first RMZ-955 instead of the flood emitter.  
When 2 or more RMZ-955s are used in the same system, we sug-  
gest that you connect them so that only the first RMZ-955 distrib-  
utes IR commands to the source components and that the IR  
emitter functions of all additional RMZ-955 controllers is dis-  
abled. This avoids potential interference leading to erratic  
operation, particularly when using the front panel IR flood emit-  
ters.  
For 3 RMZ-955s (9-12 zones):  
• Remove the jumpers between terminals 2 and 3 of the TX FOR-  
MAT blocks on RMZ-955 “B” and “C” to disable their flood emit-  
ters. Leave the jumper in place on the first RMZ-955 “A” to use  
its front-panel flood emitter. Remove this jumper as well do dis-  
able the flood emitter when using remote IR emitters.  
Note: This is a suggestion only and not a hard and fast rule.  
There may be some unusual system layouts which benefit from  
multiple RMZ-955s distributing IR to the sources. This option is  
covered below as an exception to the standard practice.  
• Connect terminal 3 of the RMZ-955 “C” TX FORMAT block to  
terminal 4 on RMZ-955 “B”.  
• Connect terminal 3 of the RMZ-955 “B” TX FORMAT block to  
terminal 4 on RMZ-955 “C”. This completes the signal link to the  
IR flood emitter on RMZ-955 “A” from the other two RMZ-955s.

controller systems involves three steps:

For example, the gray jumper wire in the following illustration is  
used to activate the front-panel flood emitter on RMZ-955 “B” in  
addition to “A”.  
For 4 RMZ-955s (13-16 zones):  
• Remove the jumpers between terminals 2 and 3 of the TX FOR-  
MAT blocks on RMZ-955 “B” and “C” and “D” to disable their  
flood emitters. Leave the jumper in place on the first RMZ-955

Use this jumper arrangement to enable the front

Paging Connections  
Exception: Multiple IR Flood Emitters  
When using the Paging feature in a multi-controller system, two  
additional installation steps are required. See page 11 for an  
overview of the paging feature.  
As stated above, the general practice is to send IR commands to  
the source components from only the first RMZ-955 and to dis-  
able the flood emitters on all other RMZ-955 controllers. The pur-  
pose of this rule is to prevent IR signals from two different flood  
emitters interfering with each other and confusing the source  
component.  
a) To trigger the muting and/or paging function, it is necessary to  
connect the Paging Trigger input to all RMZ-955 controllers. This  
requires making multiple connections from whatever device or  
mechanism is used to supply a shorting input.  
An exception to this general rule might arise in systems where  
some source components are housed in one closed cabinet and  
others in a different closed cabinet. In this case, you may wish to  
use two or more RMZ-955 controllers, one in each cabinet, to  
distribute the IR signals from their flood emitters to the source  
components.  
b) For announcements to be heard in all zones connected to all  
RMZ-955s, the paging audio signal must be distributed to all con-  
trollers. This can be done by connecting the Paging Audio Output  
on the first RMZ-955 to the Paging Audio Input on the second  
RMZ-955, using a standard RCA to RCA interconnect cable. Re-  
peat this connection from the second to the third controller and  
from the third to the fourth, if necessary.  
This can be accomplished with a jumper wire from Terminal 2 of  
the first RMZ-955’s TX-Form block to Terminal 2 on any other  
RMZ-955 that needs to have its front-panel flood emitter acti-  
vated.

INSTALLATION: MULTI-CONTROLLER SYSTEMS  
Notes on multi-controller set-up  
Power Toggle Set-up  
We recommend in systems with multiple RMZ-955 controllers  
(with full AC control from any Zone) that you select source com-  
ponents that do not require a “power toggle” command, i.e. com-  
ponents that fully power up when AC power is applied, instead of  
going into a standby mode.  
If sources requiring a “power toggle” command are used, only  
one RMZ-955 controller should have the “power toggle” feature  
activated (i.e. set to “y” during setup). Make sure that the  
“Power Toggle” command is DEACTIVATED for all other  
RMZ-955(s).  
Even though the default “Power Toggle” setting is OFF, verify that  
this has not changed by temporarily connecting an RSM-901 to  
the Zone A data terminal of each remaining RMZ-955, entering  
Set-up Mode as outlined and pressing the RLC-900 “n” (for No)  
key. Continue to hold the “n” key and press the other set-up key  
“y” to exit setup.  
This is a critical step in a system using multiple RMZ-955s. If  
the “Power Toggle” is not deactivated for the additional  
RMZ-955(s), source components will not turn on and off properly  
— in fact, source components may actually turn off when  
RMZ-955s turn on.  
Source Component Set-up  
Programming of command code sets for source components is  
covered in the following section of the manual. However, keep in  
mind that in systems with multiple RMZ-955 controllers, it will be  
necessary to reprogram these codes for each RMZ-955 in the  
system. This must be done from an RSM-901 sensor display con-  
nected to Zone A on each controller.  
“Engaged” Indicator  
The “Engaged” indicator on a remote zone’s RSM-901 sensor/  
display(s) will indicate other same-source users only in zones  
connected to that particular RMZ-955 controller/amplifier.  
For example, in an 8-zone system using two RMZ-955s, a CD lis-  
tener in Zone 7 (connected to the second RMZ-955) would have  
no indication that another user in Zone 2 (connected to the first  
RMZ-955) was listening to the same source. If a third listener in  
Zone 4 then selected CD, only the listeners in Zones 2 and 4 (both  
connected to the same RMZ-955) would know that someone else  
was sharing the same source.

including Rotel multi-disc CD players. No adjustments are neces-  
sary for these components.  
In addition to Rotel source components, the RMZ-955 can be set  
to operate the following:  
Input 1 Tuners:  
Input 2 CD:  
Rotel, Sony, Pioneer, Yamaha, Denon  
Rotel, Sony, Pioneer, Yamaha, Denon, RC5  
Input 3 Tape Deck: Rotel, Sony, Pioneer, Yamaha, Denon  
Satellite TV: RCA, Sony  
Input 4 CD 2:  
Sony, Pioneer  
Laser Disc: Pioneer  
VCR:  
Sony, Panasonic  
DVD Player: Pioneer, Toshiba  
Note 1: Assign each type of component to the input specified  
above so that the label displayed by the RSM-901 (Tuner, CD,  
etc.) matches the component when each input is selected.  
Note 2: Two CD players of the same brand cannot be used in the  
same system. Chose a different brand for CD.2

Source Command Set-up  
MUTE  
a) Locate Zone A’s RSM-901 sensor/display. Source command sets  
cannot be changed from any other Zone or even from Zone As  
keypad. If in doubt, send a command with the RR-952 hand held  
remote and monitor Zone A’s green Code LED on the RMZ-955’s  
front panel: it will flash when the RMZ-955 recognizes and  
processes a command.  
RR-952  
Note: Remember that any RSM-901 sensor/display can be con-  
nected to the Zone A data terminal for this procedure. Even if  
Zone A is equipped with a wall mounted sensor/display, it is  
probably more convenient to temporarily disconnect the data  
cable from that unit and substitute another RSM-901 placed near  
the RMZ-955 and source components.  
To avoid the possibility of an IR loop when using an RSM-901 lo-  
cated near the RMZ-955, temporarily remove the jumper be-  
tween Terminals 2 and 3 of the TX FORMAT terminal block on the  
rear panel of the RMZ-955. Also make sure that any RSM-901  
used in this set-up sequence has the circuit board DIP switches  
set for Zone A and “Master” (See page 13).

SYSTEM SET-UP & PROGRAMMING  
e) Push the desired command code button for the component you  
want to change. The available choices for that input are grouped  
together on the Set Up Card. Upon receiving your selection, the  
RSM-901 will display one of the following characters to indicate  
your choice of custom command sets:  
Power Toggle  
If you choose to power source components from the RMZ-955’s  
Switched AC outlet and your system includes components which  
normally power on in a standby mode, you will need to ACTIVATE  
the RMZ-955s software-based “Power Toggle” command.

when first plugged into the wall or when AC power becomes  
available.

Source components connected through a switched outlet or the  
RLC-900 are totally disconnected from AC when the outlets are  
switched off. Consequently, when the RMZ-955 first activates the  
source components, some go into a “standby” mode where a  
few sensors and microprocessors are powered but where major  
circuitry blocks are still inactive. The “Power Toggle” command  
tells the sensors and microprocessors to “wake up” the rest of  
the component.

• Zone activation command received. RMZ-955 ON, Switched AC  
outlet activated, source components switched ON or to  
“Standby” mode.  
Sony DSS Sat TV  
f) Repeat the above procedure for the other inputs. After you’ve se-  
lected the command codes for all the component categories you  
wish to change, exit “Set-up” by holding the right-hand SET-UP 2  
button and pushing the left-hand SET-UP 1 button. The word  
“SAVE” will appear on the RSM-901 display to indicate that the  
new configuration has been memorized.  
• RMZ-955 sends “Power Toggle” command to source compo-  
nents. “Power Toggle” triggers change from “Standby” to “On”.  
• All source components ready for remote zone use.  
The “Power Toggle” command default is OFF but it can be easily  
activated. “Power Toggle” is activated or deactivated depending  
on which of the two SET-UP bottons is pressed first when exiting  
the Set-up Mode. Press the “y” (for Yes) key first to activate  
“Power Toggle”. Continue holding the “y” key and press the “n”  
key to exit Set-up. This activates the RMZ-955s software-based  
“Power Toggle” command.  
g) For the new command sets to take effect, the RMZ-955 must be  
turned OFF (using the front panel power button) and then turned  
ON again after 30 seconds.  
All changes are stored in non-volatile memory and can not be  
accidentally erased, even by unplugging the RMZ-955. The only  
way to change command code operation is to access Set-up  
mode again.  
If source components are powered directly from an AC wall out-  
let, make sure the “Power Toggle” command is DEACTIVATED  
(the RMZ-955’s default condition) and that any source compo-  
nents featuring a “Standby” mode are “ON” before using the  
RMZ-955. To deactivate “Power Toggle”, press and hold the “n”  
key first. Then, press the “y” key to exit Set-up.  
Note: See Page 5 for further details on the “Power Toggle” com-  
mand required when the RMZ-955 system (and associated  
source components) use the switched outlet or recommended  
RLC-900 Power Line Conditioner as an AC power source.

MULTI-ROOM SYSTEM CONTROLLER RMZ-955  
Operating Instructions  
RR-952 Hand-held Remote  
As detailed in above, the RMZ-955 should ALWAYS be plugged  
into an uninterruptable AC source. This ensures that essential  
RMZ-955 system benefits such as remote controlled zone activa-  
tion and source selection are always available. Zone control de-  
vices (the RKP-901 keypad and RSM-901 sensor/display) are  
powered from the data cables and are always active as long as  
the RMZ-955 is connected to AC.  
The RR-952 remote provides easy and convenient system opera-  
tion from any zone equipped with a RSM-901 sensor/display. You  
will find that the RR-952/RSM-901s operating range is longer and  
the angle of acceptance is wider than with many other hand held  
controllers. This increased operating convenience is a direct re-  
sult of a more powerful transmitter in the remote and more sensi-  
tive receiving circuitry in the sensor/displays. Enjoy the  
difference.  
To use the RR-952 remote control, simply aim it at a wall-  
mounted RSM-901 sensor/display.  
Input Selector Buttons  
These buttons provide “one-touch” operation of the system,  
playing the selected source component in the requesting zone.  
The actual function of the buttons depends on the current sys-  
tem status, but the net effect is the same: activate the system (if  
necessary), select the desired component, put it in play mode (if  
necessary), and direct its signal to the local zone.

Note: Should you need more advanced IR controls for a particu-  
lar source, you may be able to use the source’s own dedicated IR  
remote control. In most cases, the RSM-901 and the IR repeater  
system will be able to pass IR codes directly to the source from  
any remote control.

The RKP-901 keypad offers easy access to most RMZ-955 system  
functions. The major functional difference between the RKP-901  
keypad and RR-952 hand held remote controller is that the wall-  
mounted keypad has only twelve keys.  
MUTE: Temporarily reduces system volume to almost full attenua-  
tion. Restore preselected volume levels by pressing MUTE again,  
VOL+, VOL– or any input selector.  
OFF: A brief push puts the Zone from which the command is sent  
in Standby status. All other zones are unaffected. A continuous  
push of more than 4 seconds will send a stop command to all  
source components and power down the entire system.  
Input Select commands  
These buttons provide “one-touch” operation. If the system is cur-  
rently inactive, pushing any of the four input source selection but-  
tons will “power up” the RMZ-955s and the source components,  
send the play command to the selected source, and send the sig-  
nal from that source to the zone from which the button is pushed.  
Assuming the tuner is tuned to a station, a disc in the CD player,  
etc., you will hear music with the push of a single button.  
Source Control Commands  
and : These buttons are “up” and “down” controls for operat-  
ing source components. Their function varies depending on the  
type of source currently active. See chart below.  
The function of the button changes slightly if the system is already  
active. For example, if the source selected is already playing in  
another zone, pushing the Input Select button will not send a Play  
command, but will simply let you hear what is already playing. If  
your zone is already active, pressing an Input Select button lets

Dot Matrix Display  
RSM-901 Sensor/Display  
The dot matrix display shows the following status information:  
The RSM-901 sensor/display receives IR signals from the RR-952  
hand held controller and other IR devices. It also provides feed-  
back on system status through a dot matrix LED display and indi-  
cators. In addition, it provides convenience features including a  
time of day display and a “wake to music” alarm clock function.  
Clock Display and Greeting: When the Zone is INACTIVE, the  
display shows the current time of day in a 4-digit 12-hour format.  
When the Zone is first activated, a time-appropriate greeting will  
display momentarily, followed by a display of the selected source  
component. To check the time while the Zone is ACTIVE, press
