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.

AM/FM Tuner
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-955’s “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.

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-900’s 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-955’s 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-955’s 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.

problems such as interference or “mixing” between shared
sources.
Make sure to observe correct channel continuity from source to

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:

Preamp outputs
Two RCA jacks (Left and Right Channel) labeled “Pre-out” pro-
vide line level outputs for each of the four zones. These are pri-
marily used for systems with external power amplifiers driving
speakers in one or all of the remote zones.

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 zone’s 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 zone’s 6 pin data terminal on the RMZ-955’s
rear panel. Be careful to center the connector over the terminal
pins before inserting.

INSTALLATION: RMZ-955 CONTROLLER
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-955’s 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.
CAUTION
WARNING:TO REDUCE THE RISK
OF FIRE OR ELECTRICAL SHOCK DO
NOT EXPOSE THIS EQUIPMENT TO

RISK OF ELECTRIC SHOCK
DO NOT OPEN
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-955’s 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

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.

The RSM-901 Sensor/Display mounts in a single-width wall box
or in a double width box with the RKP-901 keypad.
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
saturating the RSM-901.

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
RSM-901 in any zone, follow the simple rules to ensure that the
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
status information.
Data cable terminations and connections are made the same
way as previously detailed. As does the RSM-901, each RKP-901
has two data terminals (“In” and “Out”) located at the bottom of
its circuit board. Connect the “Out” terminal, either to the “In”
terminal of an RSM-901 in the zone, or to the RMZ-955 controller
if the zone does not have a RSM-901.

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 sensor’s 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 system’s
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-955’s 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-955’s “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

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.
The general approach to configuring IR connections for multi-
controller systems involves three steps:
RMZ-955

a) Configure the first RMZ-955 “A” to distribute IR codes to the

mote” IR emitters as described in the section on installing single
controller systems.

c) Relay IR codes from additional RMZ-955 controllers to the first
one by installing a series of jumper wires connected to the “TX-
Form” terminal block as outlined below.

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
“A” to use its front-panel flood emitter. Remove this jumper to
disable the flood emitter when using back panel IR repeaters.

Use this jumper arrangement to enable the front
panel IR flood emitters on all four RMZ-955s.
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.

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.

The RMZ-955 is factory set for use with Rotel source components,
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:

a) Locate Zone A’s RSM-901 sensor/display. Source command sets
cannot be changed from any other Zone or even from Zone A’s
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.

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).

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.

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-955’s 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-901’s 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.

PAUSE: This button momentarily stops disc play until it is pushed
again.
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.
– CHNL : If a DVD disc is playing, this button backs up to the be-
ginning of that track and continues playing. Two quick pushes
backs the player to the beginning of the PREVIOUS track or
chapter. If a VCR is selected, this changes its tuner to the next
lower channel. If CD2 is playing, this button selects “Random

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-955’s 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

OPERATING INSTRUCTIONS
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
the MODE button.
Note: The RSM-901 passes remote control IR commands to the
RMZ-955 controller at any time, regardless of whether its zone is
currently active or not.
Source Selected: When the Zone is ACTIVE, the display shows
the selected source component:

Dot Matrix Display: Shows a variety of system and zone status
information, including time of day (when the zone is inactive) and
source component selection (when the zone is active).
Engaged Indicator: It is useful to know when someone in another
Zone is listening to the same source component that is active in
your zone. If your Zone has exclusive use of the active source,
the Source indicator’s first character will be a capital letter. If
the source is “engaged” or being shared with another zone, the
first character will change to lower case.
RECEIVE LED: Flashes when the RSM-901 receives an IR control
code from the RR-952 handheld remote or RKP-901 keypad.
PM LED: Lights up when the 12 hour clock time is after 12 noon
and before 12 midnight.
ALARM LED: Lights to show that the “wake to music” alarm has
been set and will execute at the set time, activating ONLY the
Zone from which is has been set, not the whole system. If this
LED is not lit, no alarm is in effect.
