Voltage controlled eight stage OTA phaser
The Oakley Deep Equinoxe is an upgrade of the four stage OTA phaser, the Oakley Equinoxe. Both modules are named after Jean Michel Jarre's album Equinoxe as it exemplifies this wonderfully lush and smooth effect. To the Deep Equinoxe an additional pair of double stages is added, to give a total of six and eight stages respectively. This deepens the effect creating a very rich and animated sound.
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. Four front panel pots control the module:
The number of stages can be selected by either two two position toggle switches or a single three position toggle switch.
The internal LFO produces a triangle wave output which is also available from a front panel socket, LFO OUT. 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 IN socket. The module features an on board jumper to select whether the LFO OUT signal is inverted or non inverted compared to the modulating signal.
These merchants probably sell this module. Huh?
