Oakley Sounds Equinoxe: Voltage Controlled Phaser Module

"This is our hugely popular version of the classic four stage OTA based phaser. Wonderfully lush and smooth, its similar in sound to the phaser used by Jean Michel Jarre on Oxygene and Equinoxe albums.

The unit includes a useful internal low frequency oscillator with accompanying bicolour LED. The centre frequency of the phase shifter can also be controlled by an external control voltage. Thus allowing envelope generators to be used to sweep the phaser to create filter type effects.

The PCB is laid out to accept four high quality Spectrol pots:

Frequency: this controls the frequency of the two notches created by the phase shift network.

Emphasis: this accentuates the feedback signal within the phaser to create a deeper effect.

Modulation: A simple attenuator to adjust the level of the internal LFO or incoming CV.

LFO rate: adjusts the speed of the LFO.

The internal LFO produces a triangle wave output which is also available from a front panel socket. This allows you to use the internal LFO for other modulation purposes. The LFO signal is automatically routed to the modulation depth pot when no jack is inserted in the CV input. The new issue board allows a choice of inverted or non-inverted waveforms. Thus two Equinoxe units can be used for stereo phase panning.

The unit is designed to work with standard MOTM/Oakley signal levels, although it could be easily converted to be driven from other sources including an electric guitar.

This unit is also made by us, in small format, as the RS400 Phaser for the Analogue Systems' Integrator modular."
