Speaker Zones
You can group speakers in one area into speaker zones. You
can then control the audio level of the zones individually. For
example, you might want the audio quieter in the cabin and
louder on deck.
Zones 1 and 2 are powered by the on-board, Class D amplifier.
To use the four line outputs and the four subwoofer outputs, you
must connect external amplifiers.
You can set the balance, volume limit, subwoofer level, and
name for each of the available zones. Up to two pairs of
speakers can be connected per zone in parallel to increase the
amplifier output.
Subwoofer Amplifier Connection Considerations
This stereo supports output to a powered subwoofer from all
zone outputs.
The subwoofer port on the stereo outputs a mono line-level
signal. The port output audio level is linked to the zone.
• You should connect the connectors to the included splitter.
• You need a splitter for each zone. One splitter is included.
Speaker Amplifier Connection Considerations
In addition to the two stereo speaker zones available through
the wiring harness, this stereo can be connected to a separate
amplifier and speakers through the ZONE 3 connection
(optional).
• The blue wire from the wiring harness must be connected to
the amplifier to provide a signal to turn on the amplifier with
the stereo. If it is necessary to extend this blue signal wire,
use 22 AWG (0.33 mm
2
) wire.
• The audio output is a stereo line-level output over standard
RCA cable.
Common Connections to the Stereo
You can connect a variety of additional media inputs and
outputs to the stereo, depending on the stereo model and the
devices to which you are connecting.
The connectors are color coded to assist you in making the
correct connections. For example, if your TV has RCA line out
ports, you can connect an RCA cable to the AUX IN 1 or AUX IN
2 connector on the stereo. This table lists some possible ways to
connect devices to the stereo.
NOTE:
Not all connectors are available on all stereo models.

Audio Return Channel
The Audio Return Channel (ARC) enables you to play the audio
from a television with hdmi technology over the stereo system
speakers.
ARC eliminates the need to connect a separate audio cable
from the television to the stereo. Typically, in televisions without
ARC, to play the audio from the television over the stereo
system speakers, you would need a separate cable. With ARC,
the hdmi cable sends the television audio to the stereo.
The hdmi version 1.4 cables support ARC. When planning your
stereo installation, check whether your devices support ARC.
Most devices that support ARC have an ARC label on the hdmi
connector that supports ARC.
NOTE:
The Fusion MS-AV750 supports ARC.
