The Extron MVC 121 Plus is an audio mixer and volume controller that will mix up to two mono mic/line inputs (balanced/ unbalanced) with one stereo line level input (balanced/unbalanced). All audio input signals are converted from analog to digital prior to processing or routing. Each mic/line input and the line level input have their own gain control adjustment screws. The mixed variable output also features a volume control knob on the front panel.

NOTE: For full installation, configuration, and operation details, see the MVC 121 Plus User Guide, available at

Installing the MVC 121 Plus

1 MIC/LINE 2

1.Disconnect power from all equipment.

2.(Optional) Mount the unit to a rack or furniture.

3.Connect the audio inputs.

Connect up to two balanced or unbalanced mono mic/line level input devices to connector C above (see the 6-pole wiring diagram on the right). Alternatively, two 3-pole connectors may be used.

Balanced MIC Unbalanced MIC

A balanced or unbalanced stereo line level input may be connected to D above (see the 5-pole wiring diagram below).

For fixed stereo output, connect an output device to Fixed connector F (see the wiring diagram above).

5.Connect a control device. Connect a host device, such as a computer, to one of the following MVC ports to configure and control the MVC 121 plus via Simple Instruction Set (SIS™) commands.

RS-232 port (rear panel) — Connect a host device to the Tx, Rx, and

_ (ground) pins of this 6-pole captive screw connector (G). The default baud rate for this port is 38400 baud, 1 stop bit, no parity, 8 data bits, and no flow control (see the wiring diagram on the right).

Config port (front panel) — See Front Panel Features on the next page.

6.Digital input connector. Up to three configurable input ports (see H on the rear panel diagram above) allow connection to various devices including motion detectors, alarms, buttons, photo (light) sensors, and temperature sensors. This connector shares a common ground with the RS-232 connector (see the wiring diagram on the right).

Both the RS-232 and digital input connectors may be used simultaneously by using a 6-pin captive screw connector with two wires sharing the ground connector (see the diagram on the right).
