Pad Switches (Input channels 1–4)

Pad Switches (Input channels 1–4)

Input channels 1 through 4 feature 26 dB Pad switches that attenu- ate the input signal by 26 dB.

This allows the input preamp to work with hot, high-level signals, such as those from a snare drum microphone.

TRIM Controls

You can adjust the gain of the input channel preamps on input chan- nels 1 through 4 by using the Trim controls. Your goal is to optimize the input signal level to achieve the best signal-to-noise ratio.

Keep a close eye on the level meters while adjusting the Trim controls. In general, set the levels as high as possible without peaking (actually, it’s okay if the level occasionally peaks a little). If you set the level too high, the signal may distort and or clip. If it’s set too low, the output signal may sound thin or noisy.

VM200 uses “boxed” values when Pad switch is depressed.

The Trim controls have an input sensitivity of –16 dB to –60 dB, which is appropriate for many microphones. However, you can press one of the Pad switches for channels 1–4 to reduce the input sensitiv- ity for that channel to the range of +10 to –34 dB. This works well for “hot” microphone signals.

The Trim controls on input channels 5–8 have a gain range of –10 dB to –50 dB. This works well with line-level signals.

Note: Trim control settings are not stored in Scene Memory.
