The E Series amplifier accepts up to six audio sources. These can  
accept any audio component capable of supplying a line level signal.  
Preamp lineouts for each zone allow you to easily use an additional  
amplifier to power additional speakers in a zone. Only use one pair  
of 8-ohm speakers per zone.  
Preamp LINEOUTS:  
Individual stereo speaker outputs provide 20 watts output per channel  
to each zone.

Audiolink:  
This multi-pin connection is used to transfer the audio information from  
the E Series main amplifier to the expander amplifier. This output is  
used to expand the system to twelve zones.  
These outputs transfer IR signals from the zones to your source  
components. They are routed odd and even so that when source  
1, 3, or 5 is selected at any of the keypads, the IR outputs 1, 3, and 5  
all flash IR commands. Similarly, when source 2, 4, or 6 is  
selected at any of the keypads, the IR outputs 2, 4, and 6 all flash.  
The “Sum” output always flashes IR commands regardless of the  
source selected.

INSTALLING YOUR E SERIES  
SYSTEM  
I. Installing and Terminating Cables  
The basic installation requires two different types of  
cables. The keypads communicate with the E6M  
amplifier through Cat-5 data cable (4 twisted-pair). This  
cable is terminated at both ends with RJ45 connectors.  
The wiring scheme is standard EIA/TIA 568A, which is  
a standard for computer networking (see Fig. 1). These  
cables are routed in walls, crawl spaces, or attics, and  
go from the location of each keypad to the location of  
the E-Z Port hub.

Pair 3  
It is important to use a high-quality crimptool to  
assure the best possible connections. Testing each  
termination with a Cat-5 cable tester is crucial before  
installing the keypads. Improperly wired cable can  
damage the E6M amplifier or the keypads.  
After stripping the insulation off a portion of  
the Cat-5, untwist the wires and fan them  
out in the correct color order from left to  
right. Each of the RJ-45 connectors is  
terminated in the following pin order again  
from left to right.  
The second type of cable used is AWG 16-2 or 16-4  
speaker cable (AWG 14-gage can be used as well).  
These are routed in the walls, crawl spaces, or attics,  
and go from the location of a speaker to the location of  
the E6M amplifier. These cables are terminated at the  
E6M using the supplied 4-pin terminal block connectors.  
Pin #  
1. Green Stripe  
2. Green  
3. Orange Stripe  
4. Blue  
Using more than one pair of 8-ohm speakers is not  
recommended. Doing so could overheat and damage  
the amplifier and will void the warranty.  
5. Blue Stripe  
6. Orange  
7. Brown Stripe  
8. Brown  
When routing the Cat-5 and speaker cables, be  
careful to avoid running them in parallel with any  
other cables, such as AC, low voltage lighting, or  
home automation.  
Note: Colors listed as “Stripe” are a white  
wire with a colored stripe. In other words,  
Orange Stripe is a white wire with orange  
stripes.  
Important Note: This unit generates large amounts  
of heat so please remember to allow for adequate  
ventilation. The top clearance must be at least 1  
inch (25mm).

II. Installing the E-Z Port Hub  
Fig. 2: E-Z Port Backside  
The location of the E-Z Port is mostly determined by where  
you locate the E6M amplifier. All Cat-5 cables should be  
terminated and routed to this location. Once this is done,  
installation of the E-Z Port is easy.  
Plug each of the keypad cables into one of fifteen available  
jacks on the back of the E-Z Port (Fig. 2). The jacks are  
numbered 1-15, although order is not important to the  
system’s operation.  
Once all the Cat-5 cables are plugged into the E-Z Port,  
it can then be easily mounted into any commercially  
available dual-gang J-box or mud ring.  
Cat-5 cables from keypads.  
III. Connecting the E6M to the E-Z Port  
Once you have installed the E-Z Port, connect it to the E6M  
using the supplied 10 ft. Cat-5 cable supplied with the package  
(Fig. 3).

Both RJ45 connectors are wired identically with the 568A wiring  
scheme, so either end is connected to the E-Z Port, with the  
opposite end connecting to the “Network Input” on the back of  
the E6M.

IV. Attaching Source Equipment to the E6M  
Fig. 4: Source Inputs  
Each piece of source equipment is connected to the E6M  
amplifier with RCA cables. These go from the RCA output  
on the back of the source equipment to the RCA source inputs  
on the back of the E6M (Fig. 4).  
INPUT SOURCES

Any unused inputs should be shorted-circuited with the  
supplied RCA shunts. This prevents any possibility of  
crosstalk between the sources.  
RCA Shunts are provided with the E6M  
and E6X packages and should be used  
to short-circuit any unused source inputs.  
V. Connecting the IR Emitters  
Fig. 5: IR Emitter Outputs  
IR commands are transferred from the E6M amplifier  
to the source equipment via mini IR mouse emitters.  
Four of these are supplied with your E Series system.  
The emitters are plugged into the “IR Emitter Outputs”  
(Fig. 5).

Outputs 1-6 are routed to the odd and even sources.  
In other words, if source 1, 3, or 5 is selected at the  
keypad, then emitters 1, 3, and 5 all flash, as does the  
“Sum” output. If source 2, 4, or 6 is selected, then  
emitters 2, 4, and 6 all flash, as does the “Sum” output.  
IR source routing allows you to have two identical  
sources and still have independent control of those two  
sources.  
The NV-VEC emitter flasher has an  
adhesive pad that attaches directly  
over the IR receiver window on the  
source equipment.  
If IR repeating is needed while the zone is turned  
“OFF,” only the 1, 3, 5, and “Sum” outputs are  
active.

VI. Connecting the E6M to the E6X  
Fig. 6: Audiolink and Datalink Connection  
Six additional zones can be added to the E6M. This is  
E6X Amplifier  
accomplished by adding the E6X expander unit. The  
connection is made by using the 37-pin “Audiolink” cable  
and the 26-pin “Datalink” cable supplied with the E6X  
package (Fig. 6).

The three addresses labeled ZN 1*, 2*, and 3* are  
set aside so that two keypads can be used in zones  
1, 2, and 3. For instance, zone 1 can have two keypads:  
one addressed 1-0-0-0 and one addressed 1-0-1-1  
(Fig. 9). This allows for a total of 15 keypads in a 12-

Switch 7 allows you to group multiple keypads so that  
when a source is changed on one grouped keypad,  
all other grouped keypads will also change. This is  
handy for open floor plans where you might not want  
different sources interfering with each other. Source  
grouping is active when switch 7 is in the up position  
(Fig. 11).

Once the DIP switches for each zone are set, they  
can be installed in most standard J-boxes (we  
recommend the Slater model # S1-18-W), but not  
all. The width of the keypad is 51mm or 2 inches. It  
is important to make sure that the keypads are  
compatible with the J-boxes being used in the  
installation.

IX. NV-RC1 REMOTE CONTROL  
All NUVO products come with the wireless remote. This  
Fig. 13: NV-RC1 Remote  
remote will control all functions of the NV-EKP keypad. To  
control the E Series, move the “Device Selector” switch on  
the upper right side of the RC1 to “Multi-room.” Now the  
numeric buttons will select the source (#1-#6), and the five  
buttons in the “Multi-room” section will correspond exactly to  
the EKP keypad.  
NV-RC1 Remote  
Learning Remote  
The RC1 can also be used to teach any learning remote  
control all of its internal commands (Fig. 13).  
Refer to the owner’s manual for your  
learning remote control to place that  
device in learn mode. Once you have  
chosen a page for storing the E Series’  
internal functions, i.e., source selection,  
volume, etc., you can then easily teach  
these functions to your learning remote  
and have complete wireless control of  
your NUVO system.  
X. Using the “Mute” and “Unit On” Pins  
Fig. 15: “Mute In” and “Unit On” Pins  
The “Mute” input can be used to mute the system by  
providing a dry closure to these pins (Fig. 14). In other  
words, any short-circuit across this input will temporarily  
mute the system. This can be useful for providing a mute  
when the phone, or doorbell ring. Most home automation  
devices can provide this type of output.

The “Mute ” is an external mute switch.  
This can be as simple as a 2-conductor  
wire from a relay closure on a home  
automation system or phone system to the  
E6M unit. This will short-circuit the input, and  
mute the system when the doorbell or phone  
is rung.  
The “Unit On” pins will provide a +12Vdc at 100mA output  
when any zone is “ON.” This can be used via a signal-  
sensing power strip to switch on other equipment when  
the E Series system is being used.

XI. MPU Diagnostic LEDs  
Fig. 15: Diagnostic LEDs  
The MPU Diagnostic LEDs serve several functions.  
One function is the “lowest assignable address.” This  
is an aid in sequentially assigning the appropriate  
address on each keypad. When the system is turned  
on, and none of the keypads have been addressed,  
the diagnostic LED 0 should flash every 0.8 seconds.  
This means the first DIP switch on the keypad should  
be set in the “down” position, and the other three should  
be in the “up” position. This sets that keypad for zone  
1.You will then see diagnostic LED 1 begin to flash.  
This is indicating the next available zone setting, which  
is the second DIP switch in the “down” position and  
the other three in the “up” position. The next available  
address would then be zone 3, which is the first two  
DIP switches in the “down” position and the third and  
fourth DIP switches in the “up” position, which is  
indicated by diagnostic LED 0 and LED 1 flashing  
simultaneously. As each keypad is set, the LEDs will  
continue to cycle to the next address, with the flashing  
LEDs indicating which of the four address DIP switches  
should be in the “down” position (Fig. 15).

-INPUT- -OUTPUT-  
A steadily flashing LED indicates a  
properly functioning MPU. If all four  
LEDs are flashing twice every 0 .8  
seconds, there is a short-circuit that  
is most often a result of improperly  
wired Cat-5 cables. If all four LEDs  
flash three times every 0.8 seconds,  
there is a malfunction of the micro  
controller. If this should occur, please  
contact NUVO for proper warranty  
service.  
Important Note: Once a keypad has been addressed,  
it should be left hooked up to the system. This will  
keep the diagnostic LEDs accurately displaying  
the next available address.  
If the MPU’s bus transceiver is functioning properly,  
one or more of the Diagnostic LEDs will flash continually  
every 0.8 seconds. If the MPU’s bus transceiver sees  
a short-circuit on the bus, all four LEDs will flash ON  
twice every 0.8 seconds.  
If the MPU is not processing normally due to a  
malfunction of the micro controller, all four LEDs will  
flash ON three times every 0.8 seconds.

XII. Changing the Buttons on the NV-EKP  
Fig. 16: Changing Keypad Buttons  
The NV-EKP keypads come with 30 preprinted,  
interchangeable buttons. These have a variety of audio  
source labels for customizing the E Series system to match  
the audio components being used. Included in these are  
six genre buttons, such as Classical, Rock, Jazz, etc.  
These can be useful for components like CD changers or  
satellite receivers that can be set up for specific styles of  
music.  
Using a small  
screwdriver, release  
the tab holding the  
internal cover plate to  
the keypad, and  
remove it.

The keypads have a screwless cover plate that is easily  
removed with a small screwdriver. Under that plate is  
another smaller plate that holds the buttons in place. This  
is also easily removed with a small screwdriver. Once that  
is removed, the buttons can then be replaced either  
individually by tearing the perforation or as a complete  
strip of six buttons.

TUN 3  
The buttons have rubber tabs designed to  
fit into holes in the keypad’s PC board.  
Align the buttons you wish to use on the keypad and snap  
the internal cover plate back over them. Snap the cover  
plate back on, and the keypad is now ready to be installed  
in its location in the wall (Fig 16).  
XIII. NV-MI1 Mute Interface  
The NV-MI1 Mute Interface is an additional accessory that  
can be used to temporarily mute all zones whenever the  
phone rings or the doorbell chimes. No external power is  
needed for this purpose.

To mute the system when the doorbell chimes, simply run  
a pair of doorbell wires from the chime terminals to the  
connector on the MI1 labeled “DOORBELL A” or  
“DOORBELL B” (or both). Then connect a pair of wires  
from the “Mute Out” jack on the MIB-1 to the “Mute” pins  
on the back of the E6M amplifier (Fig. 17).

To mute the system when the phone rings, simply connect  
a standard four conductor telephone line cord (for two  
phone lines) into the “Telco In” jack, and then connect a  
pair of wires from the “Mute Out” jack on the MIB-1 to the  
“Mute In” pins on the back of the E6M amplifier (Fig. 17).  
E6M’s “Mute” input.  
Up to two phone lines from the home’s  
telephone service can be connected  
to the MI1 via typical four-conductor phone  
line with an RJ11 connector. Two doorbells  
can be connected to the MI1 from the  
doorbell chimes using two-conductor wire.  
The MI1 is not supplied with the E6M or the E6X  
packages.

Troubleshooting  
Symptom  
Probable Cause  
Remedy  
Check that you are using the  
568A wiring standard (See  
Section I. “Installing and  
Terminating Cables”).  
Improperly wired Cat-5 cable.  
When a keypad is plugged in,  
there is a loud “pop” through the  
speakers and the keypad does  
not work.  
Each keypad MUST have a  
unique address as set by DIP  
switches 1-4 (Section VIII.  
“Setting the NV-EKP Keypads”).  
There are 15 valid addresses  
available to any 12-zone system.  
Assigning identical addresses to  
more than one keypad usually  
causes this.  
My keypad is lit, but nothing  
happens when I press a button.  
Place the supplied RCA input  
shunts in any unused RCA  
source inputs (Section IV.  
“Attaching Source Equipment to  
the E6M”).  
This is a result of open source  
inputs on the back of the E6M.  
When there is a lull in the music,  
I can hear other sources playing  
in my speakers.  
The RC1 wireless remote will not  
operate the E6M.  
The RC1 is in “Tuner” mode or  
there are dead or improperly  
installed batteries.  
Make sure the “Device Selector”  
switch is in the “Multi-room”  
position and that the batteries  
are installed properly and are  
good.  
In certain zones the repeater  
does not seem to work properly.  
If the equipment that you are  
trying to control is in the zone in  
question and it is in the line of  
sight with your wireless remote,  
i.e., a rack with a glass door, then  
you are creating interference at  
the IR sensor of the source  
equipment.  
Verify that the rack equipment  
can be controlled through the  
keypad by blocking the IR sensor  
of the source equipment (but not  
the emitter) with your hand. If it  
works, then either move the  
keypad or block the sensor  
permanently.
