AURELIUS – TRI VOICE CHORUS
This is not your run of the mill chorus pedal. This compact, beautifully cased wonder is a three-voice chorus with six programmable presets and expression control. Choose from Vibrato Mode, Chorus Mode, and Rotary Mode and manipulate their Width, Rate, and Balance to achieve your ideal sound. Shift seamlessly from one mode to another to cop a blend that is all your own. One simple tap of the Preset (“Save/Recall”) switch and you can summon up to six settings of your choosing at will.

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. And by popular demand, we’ve equipped this with an expression control so you can use any TRS expression pedal to manipulate the Width, Rate or Balance. Put it in Vibrato Mode and you’ll have a really subtle chorus with a seasick vibrato and alternate quickly between the two seamlessly. And that’s only one mode. The possibilities are endless.

THREE VOICES

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 the Balance 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 centre 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 modelled 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 colour 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 favourite 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.

Dimensions: 4.75 x 2.50 x 2.25 in. (121 x 64 x 57 mm) with knobs
Current Draw: 75 mA
Input Impedance: 500 kΩ
Output Impedance: 100 Ω

TRS expression pedal wiring:
Tip: Wiper
Ring: +3.3V
Sleeve: Ground
Flexi-Switch® Technology
This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.

For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Since the switching is relay based, it requires power to pass signal.

Power
This device takes a standard 9 volt DC power supply with a 2.1mm negative centre barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!

This product is covered by a limited lifetime manufacturer warranty.

Although we are not authorised to determine if any repair is covered under warranty, if the item was purchased through World of Music, then we are often the best people to facilitate the claim for you and will do so as timely as possible. Warranty does not apply to cosmetic damage or faults that are a result of user neglect. Although your mate is really handy with a soldering iron, any product modification or home repair will also result in a void warranty.

Quite often, something perceived as a fault is as simple as a faulty cable or power issue so we always suggest checking over Frequently Asked Questions on the manufacturer website first. It can be a helpful approach to getting to the bottom of a problem and save you a lot of time in getting your gear back up and running!

This item ships via courier; fully insured for your peace of mind. Orders require a signature on delivery and we suggest using an address where someone will be present for the speediest delivery time. For delivery attempts with no one present to sign, your order will be taken to the courier depot and a card will be left for you to organise redelivery.
