8.2.2.2 Input Gain

The pre-amplification of the selected input is set, using the two ANALOG GAIN and DIGITAL GAIN
controllers.
Analog Gain
Digital Gain
To match the analog and digital pre-amplification with your input signal, monitor the processor input
level, using the upper
switched to Input; otherwise change it to Input, using the appropriate
Note: Both gain controllers are active for analog input signals (refer to
Please note that the correct setting of the analog and digital pre-amplification is crucial for an optimum
signal quality in the case of analog sources.
If the Analog Gain controller is set too high and the level is subsequently attenuated with Digital Gain,
you may hear a distorted signal because of the overdriven analog input although the level display
show no overdriving.
Conversely, you may obtain a noisy input signal if Analog Gain is set very low and the required gain is
subsequently made with the Digital Gain controller. As a thumb rule, the Digital Gain controller should
be left in its position 0 dB, and Analog Gain should be used to set a well modulated input signal. It is
not until then that Digital Gain can be used to make possible required adjustments.
The position of the input module in the first place of the signal path is not variable.

Analog Gain controls the gain of the analog microphone amplifier before an
A/D conversion. The settable control range is 0 to +54 dB in 6 dB increments.
A setting of 0 dB corresponds to the level set for the analog inputs in the
Levels range of the VIPcon configuration software. For low-level microphone
signals higher values are normally required for analog gain (>30 dB), while
signals with a line level often do not require an analog pre-amplification (0 dB).
This parameter has naturally no influence on digital input signals.
Digital Gain controls the input gain on digital level. The control range is -20 to
+20 dBFS in 1 dB increments. Control is performed in the digital section of the
processor. Therefore, this parameter affects both analog and digital input
signals.
