• VCA-1A Voltage Controlled Attenuator

The VCA-1A is ideal for both commercial public address amplifiers and professional stereo amplifiers, allowing remote control of the volume levels via a remote 2 core cable link.

Comprising of a two channel control box and two volume control plates, the main unit is positioned between the amplifier and pre-amplifier/mixer, increasing or decreasing the signal between the units.

The system can be configured to operate as:
• Mono (1 channel in use)
• Stereo A (2 independent channels in use)
• Stereo B (1 plate controlling both channels
simultaneously)

Applications include bars, retail sites, classrooms and industrial sites.
