  If your Lexicon Controller has no output, ensure that a signal is coming into the MC-1. You can check the Status menu by pressing and holding Record/Zone 2 on the remote, then pressing OSD ON. Increase the VOLUME using the remote control and check the Front/Back and Left/Right BALANCE. Also, check the MC-1 MUTE controls to make sure they are not engaged. Verify that the amplifiers being fed by the MC-1 are operational, and check all other equipment settings and connections.
