descriPtion
The Extron MVC 121 is a high performance Microphone Volume Control and Line Level
Mixer. Equipped with RS-232 control capability, the MVC 121 is easy to integrate into existing
A/V systems where control needs to be simple and centralized, including such environments
as small classrooms and meeting rooms. The MVC 121 is designed for intuitive operation
with two microphone/line level inputs and a third, line level-only input, each with its own
volume control. The mixer also provides 48V microphone phantom power to enable the use of
condenser microphones.
