Edge ed7800 Selling as faulty because the rear two channels have a lot of noise. Similar to a buzzing. Seems to be made better or worse by the bass boost switch. Could be a dirty switch or fault. Has been in storage for many years Didn't try in bridged. Front channels seem to work fine It might benefit from some contact cleaner inside the dials and switches. 4 X 80w RMS - peak is higher. Some of the feet need bending so that it sits flat. Will be well boxed
