Polarizing Mixer

A-138c

1. Introduction

Module A-138c is a four channel mixer, that allows to

add or subtract four incoming voltages to the output

signal.

In the middle position of the corresponding control

knob the amplification is zero, i.e. the signal will be

suppressed. Turning the knob counterclockwise the

signal is subtracted from the output sum with increasing

amount. Turning the knob clockwise the signal is ad-

ded to the output sum with increasing amount.

The output control works in the same way, i.e. the

resulting output signal can be additionally attenuated

and/or inverted.

The module is used in the first place to mix control

voltages (e.g. ADSR, LFO). It can be used to mix audio

signals too but there is no difference between adding

and subtracting audio signals unless they have a fixed

phase relationship (e.g. the outputs of a VCO, or the

input and output signal of a VCF). For audio signals

without phase correlation there is no difference between

addition and subtraction for the human ear.

Control In1 works as a DC offset generator (about

-5V...+5V) provided that no patch cord is plugged into

socket Input 1. If this feature is not required it can be

deactivated by removing a jumper on the pc board.

The voltage controlled version of a polarizer is the

module A-133.
