Introduction
The MX160 offers additional Zone A Left Front
Channel and Right Front Channel Balanced Outputs.
These Auxiliary Outputs (1 thru 4) may be used for
additional subwoofer outputs or for using the MX160
built-in electronic crossover circuitry. In this guide,
the example will illustrate connections along with
Setup Mode Settings for using the MX160 Electronic
Crossover Circuitry.
Almost all Loudspeakers incorporate acoustic
drivers and a passive crossover network. The passive
crossover network channels the various audio frequen-
cies to the appropriate acoustic driver taking into
account the amplitude and phases of the audio signals
the Loudspeaker reproduces. When an electronic
crossover circuitry in the MX160 is used together with
multiple Power Amplifiers and Loudspeakers, it is
very important to maintain the correct amplitude and
phases of the audio signals for accurate sound repro-
duction. Refer to pages 20 thru 22 and the MX160-
Menu-3 separate folded sheet to set the "Custom"
Crossover and Gain Settings.
Connecting the MX160 when using the
Electronic Crossover
The following connection instructions and illustra-
tion on the next page are a supplement to the MX160
Zone A Output Connection instructions on page 11
of the Owner's Manual and the separate folded sheet
"Mc2B" Diagram. It is an example of a typical Home
Theater System. Your system may vary from this,
however the actual components would be connected in
a similar manner. For additional information refer to
"Connector and Cable Information" on page 5 of the
MX160 Owner's Manual.
Power Control Connections:
1. Connect a Control Cable from the MX160 POW-
40
ER CTRL (Power Control) OUT A Jack to the
Power Control In on Zone A Power Amplifier
One.
2. Connect a Control Cable from Zone A Power Am-
plifier One Power Control Out to Zone A Power
Amplifier Two Power Control In Jack.
Perform additional Power Control Connections start-
ing with step 3 on page 11 of the MX160 Owner's
Manual.
Analog Audio Connections:
3. Connect Balanced Audio Cables from the MX160
Zone A - L (Left Front Channel) and R (Right
Front Channel) to Zone A Power Amplifier One
(High Frequencies) Inputs 1 and 3 respectively.
Note: Unbalanced Audio Connections may be used
in place of the Balanced Connections.
4. Connect Balanced Audio Cables from the MX160
Zone A - AUX 1 (Left Front Channel) and AUX
2 (Right Front Channel) to Zone A Power Ampli-
fier Two (Low Frequencies) Inputs Left and Right
respectively.
Perform additional Analog Audio Connections for
the remaining channels, HDMI Connections and AC
Power Cords by refering to steps (6 thru 11) on page
11 of the MX160 Owner's Manual.
