Gain Setup On Standard Vc Models; Gain Setup On Enhanced Vcx Models - Intelix 4001 VC User Manual

Intelix VC Series Mic/Line Mixer User Manual

4.2 Gain Setup on Standard VC Models

Preliminary steps:
1. Ensure the audio sources are connected to the channel inputs on the VC Series
mixer.
2. Ensure the VC Series mixer's output is connected to an external amplifier.
3. Set the input mic/line switches for the output channel and each input channel.
4. If condensor microphones are in use, enable the phantom power switch.
5. Set the front panel master volume knob to 7.
6. Set the front panel volume knob for the channel being setup to 7.
7. Set the external amplifier volumes to the desired acoustic levels.
8. If the channel has audible distortion at the above settings, reduce channel gain
with the input gain/trim control until the distortion is eliminated. Do not reduce
the front panel controls.

4.3 Gain Setup on Enhanced VCX Models

Preliminary steps:
1. Ensure the audio sources are connected to the channel inputs on the VC Series
mixer.
2. Ensure the VC Series mixer's output is connected to an external amplifier.
3. Set the input mic/line switches for the output channel and each input channel.
4. If condensor microphones are in use, enable the phantom power switch.
5. Set the front panel master volume knob to 0.
For each channel, please follow these additional steps:
1. Set the channel volume knob to 0.
2. While driving the channel input at its normal level, adjust the input gain/trim
control clockwise until the peak (red) LED for the channel illuminates. Then,
rotate the input gain/trim control counterclockwise until the red LED goes out
or just flickers during peaks. Note that the signal present (green) LED will stay
lit during this procedure.
3. Set the master output volume knob to 7.
4. Turn the channel volume knob to 7.
5. Adjust the front panel channel control knobs to the desired level, as indicated
on the bar graph (the bar graph should be just into the yellow range). The bar
graph monitors the overall output; however, if each channel is adjusted indi-
vidually, the graph will reflect only that channel. Typically, the knob should be
set between 5 and 8.
6. Adjust the external amplifier volume to the desired acoustic level.
7. There is no need to adjust the master output volume and amplifier settings for
each subsequent channel. Do, however, adjust the rear panel input gain/trim
control and front panel channel control knob as needed.
