Formula Sound AVC2
The AVC2 performs as an intelligent volume control and in operation is very simple.
If the average operating level is kept below the internally set threshold, the AVC2 has no effect.
If the average programmer level exceeds the threshold the unit will reduce its output level.
The level is reduced in discreet steps indicated by the l.e.d. bar graph meter on the front panel of the unit.
The action of the AVC2 is to fade between these steps and is almost undetectable in use.
The more one tries to increase the volume, the more the AVC2 will decrease it so that the system will barely change in perceived level.
If driven to maximum attenuation, the output level will be reduced by more than the increase in input level.
The mixer or pre amp feeding the AVC2 will probably be clipping, but the system will actually be at a lower than normal level.
A clip indicator is provided to show when the input stage of the AVC2 is being over driven.
Reducing the input level will gently release the attenuation provided by the AVC2.
