Question about Audio Players & Recorders
Hum is caused by shielded audio cable positioned too close to mains transformer. Open rear side panels and locate twin grey shielded cables from second amplifier board going to little printed circuit board screwed to the back of the plastic box that covers all I/O connectors. Just reroute this cable so it has more distance to the transformer and the hum will be gone!
