HM1986A: 4 Channel Bipolar Audio/CV Mixer w/ LED bar graph calibrated to 1 V/LED. Expander for Zorlon Cannon or Standalone

4-channel bipolar audio/CV mixer with LED bar graph calibrated to 1 Volt/LED. You can mix 4 inputs, optionally inverting each one, with a master offset control. The voltage value of the output is shown on the bar graph from a range of +/-5V shown on a 10-segment display.

This module can also be used to expand a model HM1986 Zorlon Cannon. An additional ribbon cable attaches behind the panel to the Zorlon. The mixer is then normalled to the 4 gate outputs for pseudorandom stepped sequences. Break any of the normals and inject your own signals into the sequence by patching into the inputs.

Specifications

• 4 inputs, 1 output
