A.The FR-7 / FR-3s / FR-7b's sound output is generated electronically and not acoustically. Therefore, when amplifying the sound, you don’t have to worry about acoustic feedback as you would when miking an acoustic accordion.
Just connect the FR-7 / FR-3s / FR-7b's line output jack directly to your PA system—no microphone is necessary. In addition to feedback elimination, the direct connection has the additional benefit of allowing the performer freedom of movement.
