Using an Amplifier and Volume Controller with the MLC
The MLC can attenuate but not amplify audio volume, so you can add an
amplifier (such as an Extron mini power amp [MPA]) to the system and an Extron
MLA-VC10 volume controller. The MLA-VC10 provides a variable control voltage
(supply voltage) of between 0 VDC and 10 VDC to remotely control the amplifier’s
volume output.
The following picture shows a typical MLC 104 Plus Series system featuring an
amplifier and volume controller.
