Cwejman MMF-6 Multi Mode Filter

The Cwejman MMF-6 is a flexible multi-mode filter with six simultaneously available filter types at individual outputs. Besides the clear sound known from Cwejman the module also has "saturated" outputs for a nice nasty sound. Way cool!

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 MMF-6 is a multi mode filter with six outputs, first three from the left; "clean" low pass, band pass and high pass. Low- band- and high pass to the right are processed by three separate (for every output) saturation circuits with two modes; soft and hard.Additionally, the filter core has so called "symmetry" control for the resonance and cutoff frequency. It is possible to control cutoff so positive and negative going signals has different cutoff frequencies, from a subtle "edge" to very dramatical character of the audio signal (including frequency division effect). Now it's possible to imitate the famous Moog filter (it can not replace it, of course), OTA based filters and others. All this by modulating symmetry by one of outputs (pre-patched to "clean" low pass output) or an external signal. Now it is possible to mix clean and saturated audio signals in any combination.

Total frequency controllable range: 5Hz to 22kHz
Maximal input/output audio signal: 20 Volts p-p
Slope: 12dB/oct
Modes: Low- Band- High Pass

All Cwejman modules are protected against reversed polarity.
