DESCRIPTION

The VCT range of remote audio volume controls offer high quality performance and style. Each unit features a 10-step attenuation plus OFF with non-stop selector giving a smooth variation in output level. Available in 25 watt and 80 watt versions, these volume controls offer excellent frequency response and efficiency.

The VCT25R and VCT80R versions include volume restoration and are suitable for either the three wire, amplifier derived volume restoration or the more common, 2 wire relay controlled volume restoration.

Volume restoration levels can be pre-set. When the restoration relay is activated the maximum volume can either be left at full volume or reduced by either -3dB or -6dB. This facility allows restored paging levels to be adjusted to suit the environment, in a noisy warehouse or a quiet office.
