A-125 Voltage Controlled Phase Shifter

Module A-125 (VC Phaser) is a voltage controlled phase shifter.

 

  • Phase shifting can be controlled either manually or by voltage control. Other parameters which can be controlled are resonance (governing the depth of the comb filtering, and tonal color) and mix (the amount of the original signal which is added to the phase-shifted signal).

    The A-125 is used to generate the typical phaser sound ("jet sound"). Due to the voltage control feature not only the usual LFO-controlled phasings but even ADSR-, random-, sequencer- or S / H-controlled phasings are possible.

Sound examples

In the first examples an LFO is used to modulate the phase shift. At the beginning the original audio signal can be heard (Mix control = CCW). Then the mix, after that the CV and then the Resonance control is turned up.

In the next example an ADSR is used for phase modulation. The modulation depth and the resonance are changed manually
