A-138m 4x4 Matrix Mixer - 20HP


The A-138m Matrix Mixer is a new way to combine and route signals. It has four inputs with volume controls for four separate outputs. Each output can be switched from Unipolar to Bipolar, for use with unipolar CV as well as bipolar audio signals. In Unipolar mode, the knobs work as attenuators, while in bipolar mode, they work as polarizers. With internal jumpers on the printed circuit board, one can adjust whether or not the top four controls work as DC offset generators when nothing is patched into the first input. Great for complex routing or various sub mixing/FX sending.
