Earthquaker Devices Aurelius Tri-Voice Chorus
The Aurelius is not your run of the mill chorus pedal. This compact, beautifully cased wonder is a three voice chorus with six programmable presets and an expression control. Inspired by the 1970s CE-1 Chorus Ensemble pedal, this digital unit has been tirelessly tweaked and fine-tuned to give you an all-encompassing chorus and vibrato experience like nothing else.

Mode V: Vibrato

This mode is a familiar traditional chorus type effect that leans towards vibrato with a triangle LFO modulating a short delay line. When theBalance control is turned fully clockwise, the dry signal is removed and the effect becomes a pitch vibrato.

Width
Controls the amplitude of the LFO and determines how wide the pitch modulation will sweep.

Rate
Adjusts the speed of the LFO.

Balance
In Mode V, the Balance control adjusts the amount of pitch modulation that is blended in with the dry signal. When the Balance control is turned fully clockwise, the dry signal is removed and the effect becomes a pitch vibrato.

Mode C: Chorus

Mode C is a blend of chorus and flanger. It has more warmth and slower rates than Mode V and uses a sine wave LFO to modulate the delay line. The Width control plays a major role in this mode and determines which type of modulation is more prominent.

Width
Controls the amplitude of the LFO and determines how wide the pitch modulation will sweep. Higher Width settings have a more pronounced flanging effect. When the Width control is turned past the center point, feedback is gradually added and makes the flanging effect more prominent.

Rate
Controls the speed of the LFO.

Balance
In Mode C, the Balance control adjusts the level of the modulated signal. Turn clockwise for a more pronounced effect.

Mode R: Rotary Chorus

Mode R is a rotary chorus effect modeled after the sound of a Leslie speaker cabinet. This effect combines both amplitude and frequency modulation for a Doppler effect.

Width
Controls the amplitude of the LFO and determines how wide the pitch modulation will sweep. Lower settings accentuate the lower woofer frequencies and higher settings accentuate the upper horn frequencies.

Rate
Controls the speed of the LFO.

Balance
In Mode R, the Balance control adjusts the wet/dry balance of the signal. Turn clockwise for a more pronounced and pulsing sub frequency effect.

Global Features:

Operating Modes

Aurelius has two operating modes which are indicated by the color of the Save/Recall switch LED. In Live Mode, the pedal will operate exactly where the controls are set and any changes will have no effect on the presets unless saved. In Preset Mode, stored presets are selected using the Preset switch, and the physical settings of the controls will be ignored.

Presets

Aurelius has six available preset slots for you to save and recall your favorite settings. The settings for each of the three controls, the Mode switch and the expression jack assignment can be saved and recalled in any of the slots.

Expression Control

Use any TRS expression pedal to take control over the Width, Rate or Balance! Different EXP assignments can be saved in each preset. You can also use Control Voltage with the EXP jack. The CV range is 0 to 3.3v.
