Cwejman DMF-2 Dual Mode/Slope Filter


The DMF-2 module consists of two identical filters with two modes: lowpass and a quasi-bandpass which are available simultaneously at separate outputs. Each filter works selectively with different filter slopes and allows overdriven sound by saturation. By lots of in- and output combinations the module can be used as two independent filters or as a parallel dual filter.

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.)



Each filter features resonance up to self-oscillation. The lowpass is switchable between the classic 24dB and a 36dB slope, the bandpass is a combination of 6dB highpass and 24dB lowpass. The volume control sets the audio level at the input up to saturation which grade is shown by LEDs. Additionally to the each filter´s separate sockets there are in- and outputs which address both filters simulaneously or carry thir audio signal.


We currently do not accept pre-orders for Cwejman modules. For some products, there are waiting lists with pre-orders from the years 2013 to 2017, which are being processed as a matter of priority.
If you’d like to be informed as soon as this module is back in stock, please activate the availability notification via e-mail.
Please note: The number of Cwejman modules is always limited and much lower than the number of interested parties. Therefore, we recommend to order IMMEDIATELY and ONLINE if a Cwejman product becomes available. Enquiries via e-mail or telephone are usually not fast enough.
If the demand is higher than the supply, unfulfillable pre-orders will be deleted. In this case you’ll receive an e-mail. (Pre-orders on the waiting lists mentioned above are excluded from this policy.)
