Once installed (connected between the mixer and the amplifier), the AVC2 is extremely easy to use. In normal operation, with the volume level below the threshold, the AVC2 has no effect.
If the average level exceeds the threshold then the output is reduced in small steps, which are clearly indicated on the front panel. The more the volume is increased, the more the AVC2 attenuates.
Ideally, the Automatic Volume Control should be mounted where its LED display can be seen by the operator. It should be installed in the signal chain, either between the mixer or preamp and the amplifiers, or between the mixer/preamp and the electronic crossover.
Connection is via XLR connectors - for inputs left and right, outputs left and right, and for auxiliary connections.
The unit is factory configured to operate at an average nominal line level of 0Vu (+4dBu) and in most cases will not need any adjustment.
The output level can be adjusted by a dial accessible through a small hole between the input and output terminal blocks. A black plastic snap rivet is provided to cover the hole after the initial set up. Further adjustments are possible and these are covered in detail in the User Manual.
