The DAF-1 is an analog stereo filter with a flexible structure and professional sound quality.
Each channel of the DAF-1 has two individual high/lowpass filters, each with separate controls for the cutoff frequency and resonance. Both filters have a slope of 24dB per octave and can be combined in four modes:
Band: Both filters work together as one bandpass filter. In this case filter 1 is highpass and filter 2 is lowpass. Because of the separate cutoff and resonance controls, you can set the width of the bandpass range and adjust different resonance values for each cutoff frequency.
Notch: Both filters work together as one notch filter. In this mode, filter1 is lowpass and filter 2 is highpass. In notch mode you can adjust the width of the band-stop range.
Parallel: Both filters work as individual lowpass filters, (24dB per octave) parallel to each other.
Serial: Audio passes through one filter and then the other, serially. Bothwork as lowpass. That results in a doubled slope giving you a lowpass filter with 48dB per octave - completely analog and stereo!
The cutoff frequencies can be modulated by the internal LFO in four different ways.
For example, you can modulate the width of the bandpass range in bandpass mode, or the manually adjusted bandpass range through the frequency range.
The second modulation source is the CV / EF section. It works either as envelope follower, or with an external control voltage or volume pedal. There are also four different modulation modes.

Besides the stereo TRS inputs on the rear panel (L/MONO and R/STEREO), there is a high-impedance mono input (TRS) on the front. The rear panel is also equipped with a CV input and a footswitch jack for the bypass function, in addition to the output jacks. |
