To avoid introducing noise and static into the audio
channels, the MediaLink Controller (if used), the power
supply, the MLA-VC10, and the amplifier or mixer
should all share the same grounding source.
The 12VDC, 1 amp power supply kit (part #70-055-01)
is not included with the MLA-VC10.
Wiring the Amp/Mixer Control connector
The illustration below shows how to wire the 3.5 mm, 2-pole
captive screw connector for controlling the amplifier or mixer.

The actual maximum control voltage depends on the
Configuration DIP switch settings, but the maximum
power output will not be reached if the amplifier's
control port voltage measures more than 10VDC.

and the amplifier
Wiring the MLA’s Amp/Mixer Control connector
In some applications the amplifier’s front panel volume
control knob may be disabled when the MLA is attached
to the amplifier’s control port.
See the illustration on page 2-9 for power wiring instructions.
The Configuration DIP switches must also be set to select the
outgoing voltage. See pages 2-7 to 2-9.
