Four-channel mixer module which can add signals (positive amplification) or subtract (negative amplification) them from the output signal.
Additionally there´s a polarizer at the output which controls the output signal.
The module is intended for adding/subtracting control voltages, but interesting, discreet effects can be achieved with audio signals shifted in phase.
3U Eurorack module, 8HP wide, 35mm deep. Current draw 20mA
