Formula Sound AVC-2D Automatic Volume Control

Formula Sound


The Formula Sound AVC-2D is an automatic volume controller with 3 different modes of operation.

The AVC-2D controls the sound level of a system to a set maximum, if the incoming signal is below the set threshold the AVC-2D has no effect. If the average programme level exceeds the set threshold the AVC-2D will reduce its gain to hold the output level at the set maximum.

When attenuating the audio signal the distortion from the AVC-2D is less than 0.01% so the quality of the audio is not compromised.

The audio signal processing is entirely analogue, control of the audio level is digital using a PIC controller. This combination gives the best control of audio levels and retains sound quality.

Warranty: 12 Months
