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.

We currently do not accept pre-orders for Cwejman products. If you are interested in this module, please use the availability notification. The number of Cwejman circuits is limited. Therefore, we recommend you to order online IMMEDIATELY when a module becomes available. Enquiries via e-mail or telephone are usually not fast enough. (More detailed information can be found on the product page.)

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.
