Doepfer A-138M Matrix Mixer mxr-pedals An extremely high input impedance

An extremely high input impedance ensures loading on pick-ups is minimal and a Class A FET (field effect transistor) circuit powered from 48V is employed to give the valve-like gain stage

Doepfer A-138M Matrix Mixer mxr-pedals An extremely high input impedanceModule A 138m is a 4 x 4 matrix mixer with switches for unipolar bipolar mode for each column. Unipolar means that the controls work as attenuators. Bipolar means that the controls work as polarizers. In this mode the amplification is zero in the middle position of the corresponding control. Turning the knob counterclockwise from the center position the signal is subtracted from the output sum with increasing amount (i. e. negative). Turning the knob
