The MX-4S is a voltage controlled stereo mixer
with four independent inputs. All parameters such as input gain, panning and
output gain (both left and right channels output level are ganged) are
controlled manually by knobs or associated CV inputs.
The mixer accept both DC and audio signals so it can be used for audio signals and control signals.
The LED bars displays the outgoing signals strength. The performances of the mixer such as low distortion and low noise, are superior thanks to "the state of the art" voltage controlled devices.
