The TSD-ML22VCA is a 2 input, 2 output true VCA with enhanced features including a high quality microphone pre amplifier. VCA's inserted prior to amplification provide a far more efficient solution than transformer-based attenuators for volume adjustment in high power music applications. The dual channel design can provide level control for two separate discrete zones or stereo sources and is perfect for use in sports bars, restaurants, hotels or other installations.

The TSD-ML22VCA also provides two high quality, low noise mic pre-amps, which allow simplification of designs that require remote microphone level adjustment. Switchable phantom power is provided for powering condenser microphones and a 12dB/octave @ 125Hz high pass filter is available on each mic input to minimize bass rumble and low frequency feedback in the system ensuring focus and clarity for the voice spectrum.

Unit requires power supply that is sold separately for proper function, multiple TSDs can be powered with one power supply based on current requirements.  Click here to use the TSD Power Calculator to find the correct power supply for your application.
