Motion MTR allow you to mix, attenuate and invert signals while having clear visual feedback of their levels.
Each channel can function as:

• Audio level control with VU meter
• CV attenuator with voltage meter
• CV inverter with voltage meter

Each input is normalled to 10v, so you can use each of them to generate fixed voltages.

Also, the outputs of channels 1, 2 and 3 are summed into Out 4 to be used as a mixer.

Patch it wildly to make it work as an attenuverter with offset, as a mixer, a VU meter or a combination of them all!
