Audio Out(put) connectors — Connect an audio output device to either
connector for balanced or unbalanced stereo audio output. A device such as a
tape recorder can be connected to the Fixed output while a power amplifier
can be connected to the Variable output. Wire each captive screw connector as

CAUTION
Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative
(-) terminal will damage the audio output circuits.
The Fixed connector outputs audio at a fixed level and is unaffected by
changes made via the front panel Volume/Adjust knob. The Variable
connector outputs audio that can be attenuated by turning the Volume knob.
Control connections

MLC/IR port — Connect a cable between this port and an optional Extron
MLC 206 MediaLink Controller or an optional IR Link IR signal repeater.
• The MLC provides remote control of input switching and volume.
• The IR Link accepts modulated IR signals from a remote control so the
remote control can be used for selecting the switcher’s inputs.
Extron Comm-Link cable is recommended for this connection. If you use
Comm-Link cable, the switcher and controller can be up to 250 feet (76.2 m)
apart. Wire the captive screw connector for connection to either an IR Link or
an MLC 206 as shown below.
