MVC 121 Plus • Setup Guide

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 , available at MVC 121 Plus User Guide

www.extron.com.

Installing the MVC 121 Plus

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 above (see the 6-pole wiring diagram on the right). Alternatively, c

two 3-pole connectors may be used.

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

4. Connect the audio output.

• For variable balanced or unbalanced stereo output controlled

by the front panel knob of the MVC 121 Plus, connect an

amplier to the Variable connector e, above (see the wiring

diagram on the right).

• For xed 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 congure 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 ow 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 congurable 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).

7. Reset button. The recessed reset button (see i on the rear panel diagram

on the previous page) is used to access various modes of resets. The green

power LED on the front panel indicates the reset mode that was used.

8. Connect power to the MVC by connecting the included 12 VDC external

power supply to the rear panel power connector (see a on the rear panel

diagram). The wiring diagram is shown on the right.

9. Install the software. Conguration and control is done via both hardware

encoders and software. The control software, DSP Congurator, is available

at www.extron.com Software and Manual Download from the Website (see

below). The control software help le contains operation descriptions.

Front Panel Features (see the front panel diagram at right)

a — This power indicator lights green when the MVC 121 Plus Power/Reset LED

is operational. The LED also blinks per mode reset.

b — Connect a PC to the USB Mini-B connector for Conﬁguration (Conﬁg) port

conguring the MVC using the DSP Congurator Software. The MVC 121 Plus

USB driver must be installed prior to using this port.

c — Rotating the encoder screw clockwise increases the gain setting. Rotating the encoder screw Mic 1 input gain control

counterclockwise decreases the gain. This adjustment controls the single gain point in the mix matrix that mixes mono mic 1

levels to the stereo output bus.

d — Rotating the encoder screw clockwise increases the gain setting. Rotating the encoder screw Mic 2 input gain control

counterclockwise decreases the gain setting. This adjustment controls the single gain point in the mix matrix that mixes

mono mic 2 levels to the stereo output bus.

e — Rotating the encoder screw clockwise increases the gain setting. Rotating the encoder Line level input 3 gain control

screw counterclockwise decreases the gain setting. This adjustment controls the single gain point in the mix matrix that

mixes line level input 3 to the stereo output bus.

f — As the mix-point gain or output volume increases or decreases, the LED indicator bar lights LED ladder indicator bar

from the bottom to the top to indicate the current mix-point or volume level. As the volume is increased or decreased within

a volume range, the top lit LED ashes once. If the knob is turned past maximum volume, all 8 LEDs ash for as long as the

knob continues to be turned. After 3 seconds of inactivity, the knob controls the variable volume output.

g Volume level adjust knob — Rotating the adjustment knob clockwise increases the output volume. Rotating the knob

counterclockwise decreases the volume.
