1FW Polarizing VCA aka RingMod The Multiplier module is a Polarizing VCA (4-quadrant multiplier) based around the precision AD633 Analog Multiplier chip. The difference from a regular VCA is that negative voltages will invert the phase of the output so you can use it, for example, to modulate a saw into a ramp. The main input is multiplied by a summation of the Intial control along with two Modulation inputs with depth controls invert/mute switches. The Initial control goes from 0V to +5V with the switch set to +, giving an amplification range of 0 to +1, and from 0 to -5V with the switch set
