7.7.19 Fixed-Gain Mode in the I-Tech HD
Fixed-gain mode makes any I-Tech HD model have the same gain, regardless
of output power.
To do that, fixed-gain mode sets the Analog input Sensitivity to 0 dB gain,
then adjusts the Fixed gain compensation fader, and the Maximum
Analog input, to achieve 26 or 32 dB of gain (if the Maximum Analog Input
is set Low), or to achieve 32 or 38 dB of gain (if the Maximum Analog Input
is set High), no matter what model the amplifier is.
However, In fixed-gain mode, the input trims (Analog, AES, CobraNet) can
still be adjusted.
