High Gain Function - Rocktron CHAMELEON User Manual

The HIGH GAIN function is only accessible in configurations which display "H-GAIN" in the configuration title.
The preamp stage in these configurations is set up to provide high gain levels for maximum sustain and distortion.
The PARAMETER SELECT control will allow you to access these High Gain parameters:
GAIN
The GAIN parameter determines the gain value in the distortion stage.
VARlAC ADJUST The VARIAC ADJUST parameter adjusts the level at which the preamp stage in the
Chameleon begins to distort. A Variac is a voltage attenuating device that plugs into an
AC wall outlet and adjusts the voltage level to any device which is plugged into it. For
years, many guitarists have plugged their amplifier heads into a Variac and reduced the
voltage coming into the amplifier from the AC wall outlet. This allows the amplifier tubes
to reach saturation at a lower input level and increases the gain produced. The VARIAC
ADJUST parameter operates in a similar manner as a conventional Variac - where
lowering the parameter value lowers the level at which saturation will take place.
BASS LVL
The post BASS LEVEL parameter adjusts the amount of low frequency information at the
output of each preset. This parameter is also accessible from the "Post EQ (Expert)"
function. (In the Post EQ function, the center frequency and bandwidth of this EQ section
are also
adjustable.)
MID LVL
The post MID LEVEL parameter adjusts the amount of mid frequency information at the
output of each preset. This parameter is also accessible from the "Post EQ (Expert)"
function. (In the Post EQ function, the center frequency and bandwidth of this EQ section
are also adjustable.)
TREBLE LVL
The post TREBLE LEVEL parameter adjusts the amount of high frequency information at
the output of each preset. This parameter is also accessible from the "Post EQ (Expert)"
function. (In the Post EQ function, the center frequency and bandwidth of this EQ section
are also adjustable.)
PRESENCE LVL
The post PRESENCE LEVEL parameter also adjusts the amount of high frequency
information at the output of each preset. This parameter is also accessible from the "Post
EQ (Expert)" function. (In the Post EQ configuration, the center frequency and bandwidth
of this EQ section are also adjustable.
