TheĀ Atlas Sound TSD-ML22VCA 2×2 Mic/Line Preamplifier and VCAĀ is a 2 input, 2 output true VCA with features including a microphone preamplifier. VCA’s inserted prior to amplification provides an efficient solution compared to 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 can be used in sports bars, restaurants, hotels or other installations.

The TSD-ML22VCA provides two mic pre-amps, which allows 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. The unit requires a power supply (not included) for operation.
