Trim Pot Insert

The Trim Pot Insert allows you to adjust the level of a signal in an insert location. The trim pot provides up to ±30dB of gain or attenuation and a phase inverter. The trim pot also has a built-in stereo peak meter after the control.

Gain/Attenuation

Phase Invert

Meters

You might use a trim pot to boost or attenuate a send or return from an external effect, or to drive an effect device. Certain effects such as the Compressor, Distortion, and Auto-Wah are very level dependent and like to see a good, strong input signal. If you are working with a weak signal, you can improve the performance of these effects inserting a trim pot and boosting the gain.

Trim pots can be used to boost the level of analog line level inputs, but it’s much better to boost the signal level before the A/D converters in order to get maximum resolution and signal-to-noise ratio from the converters.

The phase invert switch inverts the polarity of the signal. It is generally used to correct for balanced lines and mics that are wired backwards.

Test Tone/Signal Generator Insert

The test tone/signal generator insert is a handy troubleshooting aid which outputs a calibrated sine wave, white noise or pink noise. This tool, in combination with an insert meter, allows you to accurately measure the signal gain or attenuation of an internal or external device. The test tone can also be quite handy for tuning up musical instru- ments.

The sine wave oscillator frequency is variable from 20Hz-20kHz. The level is variable from off to +30dB.

White noise is a mixture of all frequencies in the audio spectrum at the same average level (analogous to white light in the visible spectrum).

Pink noise provides equal power distribution per octave. (White noise has more power in the higher octaves.) Pink noise and white noise are useful as wideband sound sources.
