About the MLA-VC10
In conjuction with a MediaLink ® Controller (MLC), 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 0 VDC to 10 VDC variable voltage remote
control port for volume control.
When used with an MLC, the MLA-VC10 can share the MLC's
12 VDC power supply. It can also be installed with an external
12 VDC power supply and a third party RS-232 control device.
Refer to the appropriate user's manual for information on how
to wire control connections to the controller, amplifier or mixer.
N
The MLA-VC10 provides a control voltage (supply
voltage) of between 0 and 10 VDC. The MLA-VC10 can
contol amplifiers that use a higher control voltage but the
amplifier's maximum volume will not be reached.
This manual describes how to measure the amplifier's control
voltage and special requirements for wiring the MLA-VC10 to
specific amplifiers.
Figure 1-1 shows a typical application of the MLA-VC10.
