Resonant Equalizer (EQ)
The RESONANT EQUALIZER (EQ) is a unique ten-band filter designed specifically for electronic sound synthesis and processing. Except for the top and bottom frequency bands, all other bands are spaced at an interval of a major seventh. This non-standard spacing avoids the very common effect of an accentuated resonance in one key, as will be the effect from graphic equalizers with octave or third-octave spacing between bands. Spacing by octaves will reinforce a regular overtone structure for one musical key, thereby producing regularly spaced formants accenting a particular tonality. The Resonant Equalizer's band spacing are much more interesting, producing formant peaks and valleys that are similar to those in acoustic instrument sounds.
There are three equalized outputs, two which mix the alternate filter bands, and one which is a mix of all filter bands. The upper (↑ COMB) lets pass the outputs of frequency bands at 61 Hz, 218 Hz, 777 Hz, 2.8KHz, and 11KHz. The lower (↓ COMB) mixes the other bands (29 Hz, 115 Hz, 411 Hz, 1.5KHz, 5.2KHz).
This equalizer is different from other equalizers in that the bands can be set to be resonant. When the knobs are in the middle position, the response at the main EQ Output is flat. When the knobs are positioned between the 9 and 3 o'clock position, up to 12 db of boost or cut is set at the band. If the knob is set beyond the 3 o'clock position, the band will become resonant, simulating the natural resonance of acoustic instrument formant structures. Below the 9 o'clock position, increased band rejection is achieved.
Dual Phase Shifter (2PHA)
[NOTE: the following description is for the single PHA module, which differs somewhat from the 2PHA.]
The VC Phaser (PHA) is perhaps the lowest noise and lowest distortion phase shifter available today. As an aid to recreating some of the subtle properties of phase delay in acoustic sounds, three separate outputs are provided with 360 degree, 720 degree, and 1080 degree of voltage controllable phase shift. A MIX output combines the 1080 degree phase shift with the input signal to produce the multiple notch filter effect that is usually associated with phase shifters. The VC Phaser's log-conforming characteristics and the manual and voltage controls enable ultra-smooth, precisely centered sweeps of phase shift for both spatial effects and timbral modification. For high-density systems. a 2'' DUAL PHASER (2PHA) is available.
Dual Audio Mixer w/ phase switch (2-3x1) (MIX2)
The Serge Dual Audio Mixer (MIX2) contains two independent mixers for audio signals. [Each section has three inputs with level control knobs]. [The top section is a three-in/one-out manual mixer with a phase switch on input 3]. [The bottom] section is a four-in/one-out manual mixer [with an additional] unity gain (non-attenuated) input. The main output of one section can be connected to the unity gain input of the other section to create larger mixing units. This module can be used as two audio mixers with three variable inputs, or as one mixer with six variable inputs. Used in combination with other mixers and VCA modules, various mixing functions can be patched.
The CROSS-FADER (XFAD) is an equal-power cross fade unit. The module has two signal inputs. As one signal increases in level at the output under manual or voltage control, the other signal decreases in level at the output. This effect is used to accurately fade one sound in while fading another out. Cross-fading with voltage control permits a smooth transformation between two different timbres. If a sound and its reverberated image (available with the Wilson Analog Delay) are sent through the cross-fader, the reverb mix can be voltage controlled. This effect can be used to modify the spatial characteristics of a sound event, from immediate presence to distant ambience. In addition to the cross-fade function, a VCA controls the output amplitude.
