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,

ampli 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 o ,

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
