way, if Zone B is in another room, a Remote Control
can be used to adjust the MX180.
If using an external IR receiver for Zone A in the
same room as the MX180, you may wish to disable
the front IR sensor, which also controls Zone A,
to avoid timing issues of receiving the remotes
commands from two Inputs. The front IR can be
turned on/o in the Setup Menu:
SETUP>System conguration>General setup

Digital Inputs
There are 8 digital Inputs in the MX180
• 4 Optical
• 1 Balanced XLR (AES/EBU)
• 3 Coaxial
These Inputs are labeled 1 through 8 on the rear of
the MX180. A Digital Optical Audio Cable Toslink
Cable would be used for Inputs 1 through 4. Input
5 accepts a Balanced XLR (AES/EBU) cable and
Inputs 6 through 8 accept Digital Audio Coaxial
Cable which use a male RCA type connector.
These Inputs are named SPDIF 1 through 8. All
names can be customized in the setup program.
Unused Inputs can be deleted (and later restored).
Analog Audio Inputs
The MX180 can accept Input from seven analog
audio sources:
• There are four pairs of RCA jacks numbered
1 through 4 above the AUDIO Inputs title on the
rear of the MX180. The left male RCA jack of
a stereo pair should plug into the top jack and
the right male RCA jack should plug in below it.
In the SETUP menu and Input selection, these
Inputs are called “Analog 1 through 4.”
• There are two pairs of XLR balanced
connections labeled “BAL IN 1” and “BAL IN
2”. The left and right pairs are next to each other
and will accept male XLR cables. Looking at
the back, left is on the left and labeled “L”, the
other is labeled “R”.
• The eight RCA jacks above the title “MULTI
CHANNEL IN” accept eight channel audio
and are called “8 Channel Analog” in the Input
menu. The channels are:
• LF (Left Front)
• C (Center)
• RF (Right Front)
• LS (Left Surround)
• RS (Right Surround)
• LRS (Left Rear Surround)
• RRS (Right Rear Surround)
• LFE (Low Frequency Eects)
All the Input names can be customized in the
SETUP program, as well as deleted and restored.
Phono Input
A gold-plated stereo pair of RCA jacks and a gold-
plated ground post are for connecting a turntable
with a moving magnet cartridge to the precision
phono preamp section of the MX180. Turning the
ground post counterclockwise will loosen the post
and reveal a hole in the post for inserting the ground
wire. Turn clockwise to secure the ground wire.
AC Power
This connection is essential. Plug the female end of
the supplied AC Power Cord into the AC connector
located in the rear right corner of the MX180. Plug
the male end of the AC Power Cord into a grounded
and functioning AC outlet.
Power Switch
The Power Switch controls the overall power to the
MX180. With the switch in the “0” position, the
standby button, or the Remote Control power button
will not turn the unit on. With the Power Switch
in the “|” position, the MX180 is in standby mode
and can be powered on and o via the front standby
switch and Remote Control.
Balanced Audio Outputs
There are 16 male balanced XLR connections on the
back of the MX180 to accommodate a wide variety
of speaker congurations. Connect balanced XLR
cables to the corresponding powered speakers or
ampliers. Here are the possible connections:
LF (Left Front)
RF (Right Front)
LS (Left Surround)
RS (Right Surround)
