QUATRO features four voltage-controlled amplifiers, each with a variable response curve control,  CV input attenuators and independent GAIN controls. As its outputs are daisy-chained, QUATRO can also be used as a mixer.

Its separate CV and GAIN controls allow for maximum versatility for shaping your sound; with no CV input and the GAIN knob turned fully CW, a gain of 1.33 can be achieved (+2.5dB), while backing it off to 3 o'clock gives unity gain (0db) in linear mode.

Given a CV input of +10V and with the GAIN knob turned fully CW, the maximum possible gain in linear operation is 3.125 (+10dB) and 750 (+57.5dB) in exponential operation, capable of bringing low-level signals up to modular level and/or clipping the **** out of them.

Its buffered daisy-chained OUTs allow for adjacent groups of 2, 3, or all 4 channels to be mixed together without signal loss.
