single mixer

The 3x1 Mixer 9B functions similarity to the Dual Mixer 27B except that it is a single mixer. A few new features have been added to extend the functionality of this simple module.

Polarity toggle switch selects the mode for the input level control knobs. In Uni-polar mode knobs work as simple 0-10
level controls. This is best for audio signals where full attenuation is desired.
Bi-polar mode changes the controls to be both inverting and non-inverting with zero in the mid position. This mode is ideal for processing control voltages as it allows easy selection of polarity.
