quadroPOL

Four voltage-controlled polarizers in 10 HP: each channel passes its input in phase or inverted, cut at the LEVEL knob's centre, and its CV IN moves that level, making a linear VCA or a ring modulator.

Key features

• LEVEL bipolar: in phase to the right, inverted to the left, silent at noon (dead zone)
• CV IN adds to LEVEL: linear VCA with an 80 dB range, ring modulation at audio rate
• With nothing in INPUT, LEVEL sets a DC from -5 to +5 V
• Unpatched outputs sum into the next channel (jumpers): 2-, 3- or 4-in-1 polarizing mixers
