How to Use the ANTI-FEEDBACK
“Anti-feedback” is a function that suppresses feedback that
occurs between the guitar and the amp. Feedback is
suppressed by cutting the volume in frequencies at which it
occurs.
The AD-8’s anti-feedback function automatically detects the
frequencies at which feedback occurs, and automatically
attenuates the sounds at the detected frequencies, so feedback
is rapidly and accurately suppressed.
Before Using the Anti-Feedback
• First, adjust the AD-8’s output level, the distance between
the guitar and the amp and between the guitar and the
speakers, the direction the guitar is facing, and other
factors making it harder for feedback to occur.
• When using the anti-feedback feature, you can suppress
feedback at one point.
• If the feedback cannot be successfully suppressed using
the anti-feedback feature, you'll need to go back and
readjust your setup.

The ANTI-FEEDBACK indicator flashes, and the
frequencies at which feedback occurs are automatically
detected.
* Refrain from producing sound while the frequency at which
feedback occurred is being detected automatically.
Once detection is completed, the indicator stops flashing
and remains lit, and sounds at the detected frequencies as
well as at frequencies one octave higher are cut.
* Anti-feedback is not applied when there is no input, or if no
feedback is detected at any frequency.

indicator is lit, the anti-feedback is cancelled, and detection of
frequencies with feedback begins again.

* The anti-feedback settings are not stored when in MANUAL
mode.
If you perform the Write operation while the ANTI-FEEDBACK
indicator is lit, the AD-8 stores the tone with the anti-feedback
applied.
Anti-feedback is always off (the ANTI-FEEDBACK indicator
is off) when the power is turned on.
