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

8MLC/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.
