Anti Feedback Function
Anti Feedback function
What is acoustic feedback?
This is an unpleasant oscillation (a whine, buzz, or howl) that occurs
when the output from a speaker is re-input to a microphone or pickup,
amplifi ed, and output again from the speaker.
This is more likely to occur when you point the microphone at a
speaker or raise the volume to a high level.
Sound continues
cycling, causing
feedback
Using the Anti Feedback function
What is the anti-feedback function?
This function suppresses the acoustic feedback that can occur
between a guitar or microphone and the amp. It does this by attenuat-
ing the sound in the frequency range at which feedback is occurring.
Feedback will be suppressed automatically when you use the
anti-feedback function.
1. Turn the [ANTI-FEEDBACK] switch ON.
The anti-feedback function will be applied to the
microphone or guitar connected to the GUITAR
CHANNEL and MIC/LINE CHANNEL inputs.
MEMO
In order to prevent feedback from occurring during your performance,
we recommend that you turn the anti-feedback function on before
you begin performing.
NOTE
The anti-feedback function will be reset when you turn the power off ,
then on again.
* If the anti-feedback function is not enough to suppress feedback,
take the following steps
• Change the direction of the guitar or microphone
• Move the guitar or microphone away from the speakers
• Lower the volume
