Formula Sound AVC-4 Digital Noise Level Controller Signal Attenuator, 4-Channel

The Formula Sound AVC-4 Digital Noise Level Controller Signal Attenuator is an analogue, stereo automatic volume controller, which means the dynamics of the sound remain the same, whereas compressors alter the sound. The AVC-4 is 2 AVC2’s in a single 1ru case.
Increasingly it is a condition of licensing that sound levels in a venue are controlled to a specified maximum level, the AVC 4 will perform this task. The AVC 4 will control the level of 2 stereo channels to a maximum set level (each stereo channel is set independently, and may have different levels). Essentially it is a dual version of the AVC 2.
