Cancel feedback button
In case of a feedback tap the “CANCEL FEEDBACK” button and the troublesome frequency is instantly notched
out of the mix, thus eliminating feedback without sacrificing tone quality. This feature set individuals notch filters
(up to 10) for multiple feedback frequencies.
1. Press this button while a feedback occurs. Available filter storage locations are: “10”. When a filter is stored
the button will flash one time red. If no filter is stored no flash will occur.
2. Reached the maximum filters storage available, the next press of the button will cause the button to blink
four times.
3. To reset all the filters stored, keep the cancel feedback button pressed for at least 2 sec. The button will turn
off.
Tip 1:
A good practice to be “feedback safe” while performing is to follow these steps:
- while setting the sound for the gig just raise the iRig Acoustic Stage channel volume (slowly) up to when the
system starts to feedback. Then, while the feedback is starting to sound as a steady note, press the CANCEL
FEEDBACK button. The feedback will disappear.
- you can then increase the volume even further and “cancel” another feedback frequency that may appear.
- put the volume level down back to the normal level you will use for the gig.
Tip 2:
When playing onstage acoustic instruments it may happen that some low notes start resonating too much with
the monitor speakers or with the PA system when played.
This is particularly annoying while playing.
iRig Acoustic Stage allows you to solve this problem this way:
- play the “critical” note and while the note is resonating press the CANCEL FEEDBACK button.
This will attenuate the note to make it level with the others and no longer a critical spot.
