Question about Harman Multimedia HK 3390 Receiver
Never troubleshoot anything with the volume cranked up. The moment you find the mispositioned control you'll damage your speakers. If something isn't audible at half volume there's a problem.
Are the speakers activated?
Check that MUTE is not turned ON.
Make sure you don't have any Tape functions selected without a corresponding device attached and functional.
