The TSD-ML22VCA is a true 2-input, 2-output VCA with enhanced features including a high-quality microphone preamp. VCAs inserted before amplification provide a much more efficient solution than transformer-based attenuators for volume adjustment in high-power musical 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 facilities.

The TSD-ML22VCA also provides two high-quality, low-noise microphone preamplifiers, enabling simplification of designs requiring remote microphone level adjustment. Switchable phantom power is provided to power condenser microphones, and a 12 dB/octave high-pass filter at 125 Hz is available on each microphone input to minimize bass rumble and low-frequency feedback in the system, ensuring focus and clarity of the voice spectrum.

The unit requires a power supply sold separately to operate properly; multiple TSDs can be powered with one power supply depending on current requirements. This unit has a 70mA power requirement, so any of the available TSD power supplies can be used with the unit. For multiple TSD applications, use the TSD Energy Calculator to determine the appropriate power supply needed.
