22.4 FLOOR AGC
Floor AGC acts both on the digital and analogue inputs
and set the compensation speed of the input signal level
variation when its level ranges between Gate and Floor
thresholds. In this range the original sound levels are mostly
preserved and the processor interventions (as indicated by the low Agc values) are reduced to a minimum.
The Floor AGC speed value is expressed in dB/sec (the number of dB amplified or attenuated in 1 sec) and can be
varied from 0 (Off state) to +6.0 dB/sec with 0.2 dB/sec step.
You can find a Recommended Setting Table
on the current page of this manual.
22.5 WORK AGC
Work AGC acts both on the digital and analogue inputs and set the compensation speed of the input channel signal level
variation when its level ranges between the Floor
and the maximum admitted Level (0 dB by default * ).
In this range the processor interventions are frequent (as indicated by the high Agc values), in order to keep an optimal
and uniform output sound level.
The Work AGC speed value is expressed in dB/sec (the number of dB amplified or attenuated in 1 sec) and can be
varied from 0 (Off state) to +6.0 dB/sec with 0.2 dB/sec step.
You can find a Recommended Setting Table
on the current page of this manual.
22.6 MAX GAIN
The MaxG parameter (Maximum Gain) set the maximum amplification value which can be reached by the AGC system.
The parameter can be varied from 0 to + 12 dB in 0.5 dB steps.
You can find a Recommended Setting Table on the last page of this manual.
