Tangle Quartet

A quad linear VCA and mixer in 8 HP: four DC coupled inputs, each through its own 2164 VCA to its own output, and a Mix output summing the channels whose output is not patched. Each Level input is attenuated by its knob and normalled to +5 V, so with no control signal the knobs make it a manual mixer.

Key features

• Four clean, bleed free linear VCAs (2164), DC coupled for audio and CV
• Level CV inputs with attenuation knobs, normalled to +5 V
• An LED per channel showing its control level
• Individual outputs and a Mix of the unpatched ones
