Doepfer A-168-1 PWM Generator


The A-168-1 PWM Generator derives pulse signals with variable width from triangle, saw or sine waveforms. - The perfect expansion for VCOs and LFOs, which don't offer these kind of options themselves. Alternatively, it is possible to process other material with rising and falling edge, for instance control voltages generated by an envelope. The pulse width can be adjusted manually plus there is a CV input. Results are emitted by a normal and an inverted output.



The A-168-1 PWM Generator comes equipped with one signal input and two outputs. The latter are divided into a normal and an inverted version. LEDs visualize the module's work. The pulse width can be adjusted manually via the PW potentiometer. Additionally, there is a PWM CV input plus attenuator. The A-168-1 can be calibrated via two trim potentiometers. It is meant to be the constant partner for one signal source. Besides waveforms emitted by a VCO or LFO, the module can also process other audio material respectively control voltages with rising and falling edge. However, it is not possible to use square or pulse waves as source signals.
