Channel 1 has a bi-polar attenuator for gain adjustment/inversion. The gain can of this channel can be voltage controlled. As this VCA is a four-quadrant multiplier, you can use this whole section as a ring modulator.
Channel 2 has also a bipolar attenautor.
Channel 3 has no controls and is trimmed to unity gain.
The delay time between receiving trigger and firing the envelope can be set with the potentiometer on the top right. The envelope's function can be switched from attack/decay to attack/release with the button. Use +/- of the Zoom module and press the button to assign the envelope either to modulation depth of channel 1's VCA or to the gain of channel 2.
With the optional Zoom expander module you can use all potentiometers (i.e. the parameter controls and the CV attenuators) of the Mungo modules with coarse, normal or very fine resolution. That is great for fine tuning frequencies or delay times. No matter how many Mungo modules you own, you need just one Zoom module.
