Doepfer - A-152

Module A152 is a very useful switching and T/H module. It combines a voltage addressed 1-to-8 multiplexer and 8 fold T/H that can be used as an analog shift register too. The active in/output is displayed by a LED. The digital output of the currently addressed step outputs "high". The remaining digital outputs are low. Instead of voltage control even clock/reset controlled addressing of the active step is possible. The rising edge of each clock signal causes an advance to the next state. The rising edge of the reset signal resets to step 1. Basis principles: The sum of the voltages coming from the manual Address control and the CV input define the currently addressed step of the 3 sub-devices. If the module is controlled by clock and reset the control voltage has to remain unchanged as the CV control has priority over the clock/reset control (e.g. simply turn the CV control fully counterclockwise and do not touch the Address control knob). Sub-device #1 is the bidirectional 8-fold mult
