Shakmat Modular Dual Dagger
Stereo dual filter with bandpass link and pan CV
6 HP Eurorack module
The Dual Dagger is a stereo dual filter module containing four analogue filters: two low-pass and two high-pass, each with a -24dB/octave slope. It offers independent cutoff control for each filter type, a shared assignable resonance, a Link mode that creates an 8th-order stereo bandpass filter, and pan CV inputs that offset cutoff frequencies between left and right channels for rich stereo treatment.
Features
- Four analogue filters: two low-pass and two high-pass, all -24dB/octave slope
- Independent LPF and HPF cutoff frequency control via potentiometers and CV inputs
- Shared resonance potentiometer assignable to low-pass, high-pass, or both via switches
- Link switch creates 8th-order stereo bandpass filter with CV over frequency and bandwidth
- Pan CV inputs offset cutoff frequencies between left and right channels for stereo effects
- Pan LP and Pan HP CV inputs allow independent panning of each filter type
- Back-panel jumper selects limited or extended resonance range (self-oscillation capable in Hi)
- High-pass filter self-oscillates as a sine wave VCO tracking V/Oct in Hi jumper position
- Positive Pan CV opens first channel and closes second; negative voltage reverses this
- Pan and Link can be combined for stereo bandpass panning effects
- Audio inputs accept -5V to +5V signals
- Built and designed in the EU, 6HP form factor
Controls & Jacks (15)
- Audio Input 1— Audio input for channel 1.
- Low-pass Frequency— Controls the cutoff frequency of both low-pass filters. When Link is engaged, controls the bandwidth of the bandpass filter.
- Audio Input 2— Audio input for channel 2.
- Resonance— Controls the resonance of the filters. The resonance potentiometer range can be set via a rear-panel jumper to either limited (Lo) or high (
- High-pass Frequency— Controls the cutoff frequency of both high-pass filters. When Link is engaged, controls the center frequency of the bandpass filter.
- Pan High-pass CV Input— Accepts CV to pan the high-pass cutoff frequency between the two channels. Positive voltage increases channel 1 and decreases channel 2; neg
- Audio Output 1— Filtered audio output for channel 1.
- Pan Low-pass CV Input— Accepts CV to pan the low-pass cutoff frequency between the two channels. Positive voltage increases channel 1 and decreases channel 2; nega
- Resonance CV Input— Accepts CV to modulate the resonance amount on whichever filter sections have their resonance switches engaged.
- Audio Output 2— Filtered audio output for channel 2.
- High-pass CV Input— Accepts CV to modulate the high-pass cutoff frequency. When Link is engaged, modulates the bandpass center frequency.
- Low-pass CV Input— Accepts CV to modulate the low-pass cutoff frequency. When Link is engaged, modulates the bandpass bandwidth.
- Link— Engages the Link function, turning the module into an 8th order stereo bandpass filter. When active, the low-pass filters follow the high-pa
- High-pass Resonance— Enables resonance control on the high-pass filters. When engaged along with low-pass resonance switch, affects both filter sections.
- Low-pass Resonance— Enables resonance control on the low-pass filters. When engaged along with high-pass resonance switch, affects both filter sections.
