The Dual Dagger by Shakmat Modular is a lowpass/highpass filter for true stereo sound processing. The module has a total of four filters, which are divided into two lowpass and two highpass filters for the left and right channel. Since the first input is normalized to the second, mono signals can also be used at the input. The lowpass/highpass pairs can be distributed in the panorama via control voltage. The two cutoff parameters can be controlled separately, resonance can be applied to one or both filter pairs. There is a CV input for each of the three controls. The two sections can be linked together, turning the module into a 48db stereo bandpass filter where frequency, bandwidth and resonance can be controlled. Those who prefer working with stereo signals will be able to elicit exciting sounds from this module.
