Page 4: Introduction
Collide 4 is an expression of Hain- bach's extensive experience in exploring the deepest musical realms contained within vintage test equipment, and the Joranalogue philosophy of electronic in- strument design. Honouring its innovative dual-phase ar- chitecture, this new kind of musical gen- erator and processor has been chris- tened the ‘quadrature spectral com-... -

When not using external TZFM, this knob simply provides linear frequency control, with both the positive and negative fre- quency domains available. It is especially useful when Collide 4 is being used as a frequency shifter, making it easy to smoothly transition between down and up shifting though the zero point, simply by turning a single knob. - Page 14 When this switch is in the ‘X=Y’ setting, The diagram below shows the resulting the Hilbert network is bypassed, and the waveform when multiplying two sine monitor signal is applied unchanged to waves at different frequencies. both balanced modulators; X and Y are identical.
