The Cwejman FSH-1 Frequency Shifter offers you a wide-range of high-quality frequency shifting capabilities, while the module can be also used as a ring modulator. Lush and super clean tones come out of this module and modulating it is like a dream.


The main purpose with the Cwejman FSH-1 Frequency Shifter is to make frequency shift up and down for processed audio signal. Two signal sources are needed; the carrier and the audio. Both carrier and audio signals are splitted in two chains and are pre-processed to accomplish 90 degrees phase shift between splitted signals.

The carrier generator has two frequency ranges; LF (low frequency) and AUDIO and it's controlled by knobs COARSE, FINE and external CV signals (CARRIER CV). 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.

The carrier generators outputs are pure sine waveforms with 90 degrees delay between them. Outputs are patched to both ring modulators inputs. Two ring modulators (dual balanced multipliers) receives 0 and 90 degrees shifted carrier and audio signals . The outputs from the multipliers are combined in two ways; the frequency shift UP and DOWN.

The frequency shifted audio signal is a sum (UP) or difference (DOWN) of the carrier generators frequency (a pure sine waveform) and all audio signals frequencies (fundamentals and harmonics). The FSH-1 works in two modes; as frequency shifter and as dual ring modulator. A ring modulator is a classic audio effect device and due to the non-harmonic character of the output signal. It's very useful to create metallic timbres such as bells, sweeping whistles and percussive sounds and tremolo effects. The obvious effect (particularly in LF mode) is a stereo panning effect of audio signal.
