The V721 is a conventional matrix amplifier for generating mono signals from stereo signals. The device has balanced and floating inputs and outputs. The entire audio chain employs symmetric circuitry, and the headroom level from input to output is +30dBu with no passage gain.
The V721 matrix amplifier simpler alternative to the V724 - 90° filters. The correction level is adjustable by a stepped switch with the calibrated values 0dB, 1.5dB, 3dB, 4.5dB and 6dB.
The matrix amplifier is implemented with two inputs and an output.
The V721 matrix amplifier is a standard V700 module and fits into standard mounting frames.
