Noise Gate; Preamp Out Level - Alesis GT Reference Manual

Noise Gate

The display says:
Extreme compression and distortion settings, as well as hum and noise
picked up from your guitar pickups, can add undesirable noise. The
noise gate cuts off the signal when it dips below a certain threshold level,
as set by the noise gate parameter value. Set the threshold just above the
noise so that your playing exceeds the threshold and passes through the
gate, but residual noise that is present when you are not playing will not
exceed the threshold and will be blocked.
You can set the Quadraverb GT's noise gate threshold manually, or you
can enable the Auto Gate feature to set it for you. The auto gate estimates
a moderate gate level for you, depending on the amount of compression
and distortion you have chosen.
To set the noise gate manually, don't play your guitar. If you hear noise,
start with the value at Off and slowly increase value (up to 16) until the
noise goes away. With extremely noisy signals, you may have to
compromise a bit and have either a little bit of noise get through, or
have more of a noteÕs decay get cut off.

Preamp Out Level

The display says:
The Preamp Out Level is located in the Quadraverb GT's digital section,
post-effects return. It controls the level of all of the analog effects as they
are fed into the processor that generates all of the QuadraVerb GT's
digital effects. Proper adjustment of the Preamp Out Level allows you to
prevent overloading of this processor without sacrificing the input level
necessary to provide sufficient gain to drive the QuadraVerb GT's analog
section properly.
To set the Preamp Out Level, do the following:
