Shakmat Dual Dagger Cheat Sheet

Type: Dual Stereo (4-pole) Filter / Stereo Bandpass
Size: 6HP | Depth: 29mm | Power: +12V: 65mA, -12V: 80mA
Audio Input Range: ±5V

Panel Controls & I/O Reference

Knobs/Potentiometers

• A. LPF: Low-pass filter cutoff (stereo)
• C. RES: Resonance (assignable: LPF, HPF, or both)
• F. HPF: High-pass filter cutoff (stereo)

Switches

• B. LINK: Links filters for stereo bandpass mode
• D. LPF Resonance Switch: Assigns resonance control to LPF
• E. HPF Resonance Switch: Assigns resonance control to HPF

CV Inputs (all DC coupled)

• PANLP: Offsets L/R LPF cutoff in opposite directions with voltage
• PANHP: Offsets L/R HPF cutoff in opposite directions with voltage

Audio Inputs & Outputs

Quick Start

Filtering Basics

• LPF/HPF knobs: Adjust stereo low/high-pass cutoffs.
• RES knob: Control filter resonance. Assign to LPF, HPF or both with toggle switches.
• LINK switch: Engaged = bandpass mode. HPF = band edge (start freq), LPF = bandwidth.

Voltage Control

• All primary functions (LPF, HPF, RES, PANLP, PANHP) are voltage controllable with ±5V.
• PAN inputs let you offset cutoff oppositely on L/R for powerful stereo effects.

Stereo Bandpass

• LINK on: HPF cutoff is lower band edge, LPF sets bandwidth. Resonance applied at band edges via switches.

Resonance Jumpers (on rear)

• "Lo": Safer (no self-oscillation)
• "Hi": Allows self-oscillation (VCO uses!)

Essential Patch Ideas

• Stereo Filtering/Animation: Standard stereo filtering and animated stereo panning via PAN inputs.
• Double Peaks: Mono in, both outs mixed = double peak filter. PAN controls separation between peaks.
• Sine VCO: One channel can self-oscillate as a sine VCO (in Hi jumper mode).
• Kick Drums: Envelope FM the cutoff for snappy drum sounds.
• Mid/Side Filtering: Combine with M/S modules (e.g. Shakmat SumDif) for creative stereo processing.
