AVC-2 Automatic Volume Control

The AVC-2D is an enhanced version of the AVC2 automatic volume control system, offering full control of music levels without compromising the audio quality.

The AVC2D 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 AVC2D has no effect. If the average programme 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 AVC2D is to fade between these steps and is almost undetectable in use. The more one tries to increase the volume, the more the AVC2D 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 AVC2D 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 AVC2D is being over driven. Reducing the input level will gently release the attenuation provided by the AVC2D.

Product Features

There is no reduction in the dynamic range of the system under normal operating conditions
The AVC2 has no external controls for the operator to worry about which also means that tampering is minimised. A bar graph meter informs he operator how much level the unit is holding.
An anti-tamper relay is fitted which can be connected to an external switch to improve system security.
The unit has provision to connect to an external time switch (not supplied) to switch between two output levels.
An external remote warning indicator may be connected to warn the operator that the operating level is 3dB away from the threshold at which the AVC2 will start to control level.
