Introduction
About the MLA-VC10
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.
