Panel Descriptions

VMIX Front Panel

1. Input Volume Controls

Each of the 8 inputs is controlled by an independent volume control.

2. Signal / Clip Indicators

A single two-color LED located above each channel’s volume control indicates the audio activity of that
channel’s input. Green indicates signal present at the input; red indicates clipping of the input signal.

3.Treble Control

Controls the amount of cut or boost of treble frequencies above 10 kHz.

4. LED Output Meter

An 11-segment LED output level meter monitors the output level of the mixer.

5. Master Volume Control

Controls overall level of mixed input signals.

6. Power Indicator

An LED indicates AC power status.

7. Bass Control

Controls the amount of cut or boost of bass frequencies below 100 Hz.

8. Peak Hold Switch

This switch determines whether the LED Output Meter temporarily holds the peak output level for signals
above “0” on the meter.

9. Power Switch

Controls AC power to the mixer.
