To save these settings, move the Play/Edit switch back to Play or
move the Image Select knob to another position. Note that when
you switch to Play, you freeze the tone settings for the last selected
Sound Image(s). When you return to Edit, your Bass, Mid and Treble
settings for the Sound Image(s) will not change until you move the
respective sliders.
Phase and Anti-Feedback
These controls work hand in hand to suppress acoustic feedback.
When set properly, you can play your instrument as loud as you like,
feedback-free.
Phase (global)
This switch inverts the phase at the Onboard Aura's output and acts
on both the pickup and the selected Acoustic Sound Image. Push the
Phase switch in and out several times until you find the position that
sounds best and subdues feedback.
Relative Phase (Pickup Phase)
To change the character of your blended sound, you may wish
to invert the phase of the pickup relative to the Sound Image(s).
There is no "best" position for relative phase, and where you set
it is a matter of personal taste.
1.
Center the Blend slider and switch to Edit.
2.
Push the Tuner button to toggle between positive pickup polarity
(above pitch arrow in tuner) and negative pickup polarity (below
pitch arrow in tuner) until you find the setting that sounds best.
3.
To exit this parameter, move the Play/Edit switch to Play.
You may program a different relative pickup phase setting for each of
the six Sound Images. Select a different Sound Image and repeat the
above procedure.
