About the MLA-VC10 (part #60-502-01)

Along with an RS-232 host device, the Extron MediaLink™ Accessory Volume Control 10 (MLA-VC10) can be used to remotely control the volume output of an audio mixer or amplifier that has a 0VDC to 10VDC variable voltage remote control port for volume control.

The MLA-VC10 can be installed with an Extron MediaLink Controller (MLC) and the MLC’s 12VDC power supply, or the MLA-VC10 can be installed with an external 12VDC power supply and a third party RS-232 control device.

Refer to the appropriate controller’s, amplifier’s, or mixer’s user’s manual for information on how to wire control connections.

The MLA-VC10 provides a control voltage (supply voltage) of between 0VDC and 10VDC. The MLA-VC10 can control amplifiers that use a higher control voltage. However, if the MLA-VC10 is used with devices that use a control port voltage above 10VDC, the maximum volume will not be reached.

The illustration below shows a typical application.
