From the 1982 catalog: 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.
Note that the raw 360 degree, 720 degree, and 1080 degree do not provide the classic phasing sound. They must be mixed with the incoming signal for this to occur. The MIX output does this onboard with the 1080 degree output. The two MIX mixers provided on the PCB are to allow you to experiment with mixing the signals, both straight and inverted (these mixers are inverting mixers), as well as experimenting with feedback by mixing the signal to be processed with the phase shifted outputs before feeding it into the input of the phaser itself. Feedback experiments require the use of AC coupled mixers such as these to prevent any op-amp offset cascading and driving the unit into distortion.
