Wiring for remote control
Options for remote control include the Extron VC 50, VCM 100 AAP, VCM 100 MAAP, VCM 200 series, and MLA VC10 Plus. For information about part numbers, see www.extron.com. Third party 10k potentiometer volume controllers can also be connected to this port.
Figure 4 and the instructions below, show the wiring for the VCM 100 MAAP. Wiring other remote control connectors is similar.

Figure 4. Remote Control Wiring
•Pin 1 is 10 VDC reference voltage.
•Pin 2 (Vol/Mute) can be used as a variable voltage input between 0 and 10 VDC, with 0 V giving full attenuation and 10 V giving maximum volume. It can also be used for remote control muting. Sound is muted while the mute pin is shorted to ground.
•Pin 3 is ground.
NOTE: All nominal levels are at ± 10%.
