4.8.19 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, fi xed-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 amplifi er is.

However, In fi xed-gain mode, the input trims (Analog, AES, CobraNet) can still be adjusted.
