ELLIPSE AURA™ (for factory installed systems)

Quick Start
Before you begin, set the controls as illustrated:
2

3
1. Plug In • Connect the Ellipse Aura to your amplifier or PA with a 1/4-inch instrument cable.
2. Select a Sound Image • Raise the Volume and use the Sound Image switch to browse through the
four Images until you find one you prefer.
3. Blend in the pickup • Move the Blend slider to the left to mix in some pickup signal with the
Sound Image.
4. Phase • Push the Phase switch in and out until you find the position that sounds most pleasing.
If feedback occurs, change the position of the switch.
5. Anti-Feedback • Start with the Volume off. Move the Anti-Feedback switch to the On position (left).
Push and hold the measure button for several seconds. Raise the volume until feedback begins.
The filter will latch onto the feedback and eliminate it after a few seconds.

Power
Plug in the guitar, and the Ellipse Aura switches on. To conserve the battery, remove the instrument
cable from the guitar when the system is not used.
When you plug in, the Battery LED flashes once to indicate power up. We observe this convention
(in place of a steadily lit pilot lamp) to extend the useful battery life.

Battery Replacement
When the Battery LED lights steadily, it is time to change the battery. To replace the battery, remove the
fabric bag inside the guitar. We recommend a lithium type for extended battery life. You can expect up
to 80 hours from a lithium battery and 33 hours from an alkaline battery.
If you ship your guitar, we recommend you remove the battery. Although unlikely, it is possible for the
battery to jar loose during shipment and damage your instrument.

Controls
The controls are arranged in two distinct levels. Once your fingers are familiar with the layout, you will
be able to easily adjust the controls, even when you can’t see them.

7
1. Blend
Use the Blend slider to adjust the balance between the pickup and the Sound Image. You’ll attain
amore microphone-like sound by favoring the Sound Image. Note that it is often practical to
blend in a higher percentage of the pickup in live situations, especially when you desire more
focused amplified tone.
2. Phase
Use the Phase switch to improve bass response at low volume and suppress feedback at high
volume. Push the Phase switch in and out, and leave it in the position most pleasing to your ear.
If feedback occurs, push the switch again.
3. Volume
For the cleanest noise-free sound, set the volume as high as possible without causing your
amp or mixer to distort.

4. Anti-Feedback
The Ellipse Aura is equipped with an automatic search-and-destroy notch filter. Toengage the
feature, turn the Volume down and move the Anti-Feedback switch left (on position). Hold the
measurebutton for a few seconds. The BatteryLED will begin to flash. Turn up the volume, then
either dampen the strings while tapping the body or play the troublesome note until feedback
begins. The filter will latch onto the feedback, eliminate it after a few seconds and hold the setting
in memory until you push the Measure button again. If you plan to record with the Ellipse Aura,
we recommend you turnoffthe Anti-Feedback to fill out the natural low-end response of the guitar.

5. Sound Image Switch
Your Ellipse Aura is factory loaded with four Sound Images created especially for this instrument.
Each Sound Image corresponds to a different microphone type and distance. Contact the guitar
manufacturer to identify the microphone associated with each Sound Image.
6. Voicing Switch
This switch selects how the pickup is voiced. Move the Voicing Switch to the left for bass boost
and to the right for a flat response. Choose the setting that works for your instrument and your
performance requirements. Here are some guidelines.
•The boosted bass voicing (switch to left) complements solo guitarists and singers who
accompany themselves, especially with smaller instruments.
• The flat voicing (switch to right) cuts through the mix if you play in a band. It does a
good job controlling boominess and low frequency feedback onstage, especially with
full-size guitars.

Input Trim
Adjust this set-and-forget control so you can play strongly without distortion and play quietly without hiss.
To set the Input Trim:
1. Move the Sound Image switch left to #1.
2. Hold down the Measure switch as you plug in the guitar.
3. Use a miniature jeweler’s screwdriver to gently raise or lower the Input Trim so the LED flashes
occasionally with hard playing.
4. Toexit the setup, unplug the guitar. Input Trim
