Cwejman FSH-1 Frequency Shifter


The FSH-1 module is a voltage controlled frequency shifter in studio quality. Unlike to other product on the market there is no bleedthrough of the internal oscillator and no audible noise! The signals can be up- and down-shifted; alternatively the module can be used as a high-quality ring modulator.



The carrier frequency of the oscillator can be switched into LFO mode and reaches from .01Hz to14kHz!
Two audio signals can be connected, of which the first one´s level can be adjusted. There´s also a coarse and fine tune control for the VCO and frequency modulation inputs. Generally all Cwejman modules are shielded from interferences and contain lots of calibration possibilities on the backside, see picture.


Audio: 2x In, 3x Out (downshifted signal, upshifted signal, mix of both)
CV inputs: 1x Mix, 2x Carrier Frequency
