  If your Marantz Tuner isn't producing any sound, there are a few things to check: * Ensure the INPUT SELECTOR on your amplifier is set to “TUNER”. * Verify that the volume on the amplifier isn't set to “MIN.”; adjust it accordingly. * Make sure the terminal for system connection is correctly connected.
