BHWR rectifier


Bipolar Half-Wave Rectifier

The abbreviation BHWR stands for bipolar half-wave rectifier. It is a passive dual module offering a new wave shaping concept, routing options and new sounds.
In simple words the BHWR splits a signal into its positive and negative half-wave or it combines due to its bi-polarity the half-waves of two different signals into a new one.

Standard use:
The BHWR splits a bipolar waveform, injected at the ± socket into their positive (+ socket) and negative (- socket) half-wave. Now you can process the both waves separately: filter them, distort, waveshape, run them thru different wave multipliers, as you like. Afterwards you can mix them for instance.

Reverse use:
In this case you can input two different signals from which the BHWR picks one positive and one negative half wave and generates a new bi-polar wave at the ± socket. For technical reasons the + socket is responsible for the negative half wave and the - socket for the positive one.
The two input signals can be at the same frequency (e.g. two wave forms form the same VCO), but also don't have to! Experiment with synchronized VCOs or two totally different frequencies.

These merchants probably sell this module. Huh?
