12.2.2.2. Input gain
Selecting «Input gain» from the «Input settings» menu opens the
corresponding subscreen.
An additional preamplifier stage (gain pot) is provided for each
input channel, either analog or digital.
This allows either analog or digital audio sources to be directly
connected to the respective amplifier input channels and presets
their upstream gain ranging from –57.5 dB to +6 dB in steps of
0.5 dB.
By factory default the input gain is set to 0 dB.
At the bottom of the screen two buttons are located providing the
following functions:
Input
gain
Master On/Off switch.
The on/off status is indicated by a change in color of
the button from grey to blue or vice versa.
Clear All gain settings are reset to factory default (0 dB)
while the function remains activated.
12.2.2.3. Fallback
The Fallback function enables the definition of primary (Regular)
and secondary (Fallback) signal paths for analog and digital input
signals with two different modes (Manual or Auto). This ensures
that any secondary or emergency signal fed to the Fallback inputs
is transmitted when required.
For this purpose, the input section is split in two logical groups:
▪
Regular signals only on input connector pair 1/2.
▪ Fallback signals only on input connector pair 3/4.
Note: The Fallback and Override functions can be used
simultaneously. However, please note that in this case input 3
is no longer available as fallback input.
