HOw TO BEGIN:

A Project Documentation Worksheet is included as part of this Install Guide.
Documenting the project as you install it will greatly speed programming and
ultimately enhance your experience. Save the Project Documentation Worksheet
for future reference.

Determine the best location for the MRC-6430 and all audio source equipment
(Media Streamer, Satellite, MP3 Player, etc).

Please follow key pad / touch panel wiring instructions included
with those products.

Run speaker wiring (maximum 14 gauge) from each speaker location
back to the MRC-6430.

Be sure to label all wires for easy documentation.

Turn off the Main Power switch to the MRC-6430 before making connections.

1. mOUNT IN CABINET OR RACk

Mount the MRC-6430 in a cabinet by setting it on a sturdy shelf. As with any
electronic device the MRC-6430 generates heat at all times, but considerably
more when all zones are playing. Ensure clear positive airow within the cabinet
by utilizing fans. Locating the MRC-6430 in a completely enclosed cabinet is
not recommended due to heat build up.

Use the included rack mount ears and hardware to mount into a standard
equipment rack. Use only the included screws to attach the ears to the
MRC-6430. Ensure adequate ventilation for the MRC-6430 by placing at least
one blank rack space above and below. If the rack is completely closed use
positive ventilation to dissipate heat build up.

2. CONNECT TO NETwORk

With a category 5 (or higher) cable make a connection between the Ethernet
port on the MRC-6430 and an open Ethernet port on the local area network.
The MRC-6430 is defaulted for DHCP addressing. Static addressing is required
when using a Niles HR200 and is set using the Auriel

TM

software wizard

(see section 10).

Note the MAC ID in the Project Documentation Worksheet (extra sheet).

3. CONNECT AUdIO SOURCES

B – LOOp OUTpUTS 1 THRU 6 CONNECTION

Two MRC-6430’s may be used in a single system. This allows for 6 sources and
up to 12 zones. The sources from chassis one are shared with chassis two by
connecting the LOOP OUT from chassis one to the matching source
AUDIO INPUT on chassis two.

4. CONNECT dOORBELL INTERFACE (OpTIONAL)

Connect the AUDIO OUTPUT of the Niles DBI-2 Doorbell Interface
to the PAGE AUDIO IN using an RCA male to male cable. If you are using
an MRC-6430 Extender chassis, connect the PAGE LOOP OUT to the
PAGE AUDIO IN on the Extender chassis.

5. CONNECT ANd mOUNT IR EmITTERS

Connect the 3.5mm plug of each IR emitter into the designated port on the
MRC-6430. The IR ports, labeled 1-6, are independently routed and may be
used for any system device. Make sure to use the included System Worksheet
to note which IR port is being used for each device. When using an additional
MRC-6430 chassis to add zones 7 thru 12, the six IR outputs on the 2nd
chassis are available as additional unique IR outputs.

Unit

When controlling media room system additional IR outputs may be necessary.
IR outputs may be connected to a Niles IR Main System Unit (MSU-140,
MSU-250, MSU-480) to expand IR outputs.

6. CONNECT SpEAkERS

SpEAkER CONNECTIONS 1 – 4

CAUTION! ALL SPEAKER WIRE CONNECTIONS MUST BE MADE WITH THE RECEIVER POWER OFF.

There are four sets of removable
speaker wire terminals, one for each
zone. The terminals accept speaker
wires up to 14 AWG in size.

Each terminal has four screw-down
connections for speaker wire:

one positive (+) and one negative (-)
for each speaker. Unscrew the connection,
insert the appropriate bare speaker wire,

Correct wiring
from left to right:
L+, L-, R-, R+

then tighten rmly.

If a speaker output is unterminated, the amplier for that output is disabled by
the power-on diagnostics. Should a speaker be connected later, the amplier
for that output will be enabled during the next power-on sequence.

7. ZONE pRE-Amp OUTpUTS

A – CONNECTING ZONE pRE-Amp OUTpUTS 1 THRU 6

Each zone of the MRC-6430 has a corresponding Zone Preamp Output to
send signals to auxiliary ampliers for powering more than 1 pair of speakers
in a zone, powering speakers in zones 5 and 6, or adding additional power
to a pair of speakers in a given zone.
