Wiring The Volume Control Module (Mlc 64 Rs Vc D Only); Connecting Power To The Mlc - Medialink MLC 62 IR D User Manual

Wiring the Volume Control Module (MLC 64 RS VC D Only)

Connect the remote volume control port of an Extron amplifier to the 3-pole captive screw
connector on the rear panel of the MLC 64 volume control module, as shown in figure 26.
No software configuration is required for this module.
NOTES:
• Choose an Extron amplifier that is capable of remote volume control and muting.
Not all Extron amplifiers have remote volume control ports. The MPA 401 or
MPA 152 Plus are examples of the type of amplifier to use.
• Use shielded cable for audio connections to avoid inducing noise.
1. Wire a 3-pole captive screw connector (provided) to an audio cable as shown below:

2. Plug the wired connector into the 3-pole captive screw connector on the rear panel of
the MLC 64 volume control module.
3. Connect the other end of the audio cable to an Extron amplifier that is capable of
remote volume control (such as the XPA 1002).
