ARIES AR-329 PHASE/FLANGE MODULE

The AR-329 is a voltage controlled phaser. Usually people think of phasing as a special effect - swooshing, jet-sound, etc. Very few people have had a chance to use a phaser that isn't controlled by an internal oscillator, so fail to discover that a phaser can be uniquely effective timbral modifier. The AR-329 has a manual center frequency control to set the initial center frequency of its 4-or-5-peaked frequency response curve, and a manual centre resonance contreol which can bring this very stable device to the brink of self-oscillation (ringing) on the smalest input signal. Two input attenuators, one for ALL 4 audio signal inputs, and one for the first exponential control input complete the control complement. The control input sensitivities available make this an extraordinarily flexible unit. The first 2 control inputs are exponentially sensitive, one fixed 1v./oct. and the second attenuatable. These are used for the standard phasing effect where a sine or triangle is applied to control frequency. With the keyboard control voltage applied the AR-329 becomes a voltage-cotrolled formant filter producing four or five formant peaks whose relationship is fixed. Used this way, the 329 is a unique timbral modification. The linear input is primarily designed to be used with envelope follower outputs, and moves the phase frequency as the amplitude of the followed signal changes. The flange input has a reciprocal sensitivity whose response simulates the response of a swept flanger, which slews the swoosh up to infinity at an ever increasing rate. The EVEN mode has four formant peaks and produces a "fat" sound rich in high and low harmonics. The ODD mode has 5 formant peaks, and produces a thinner, reedy sound.
