Troubleshooting TROUBLESHOOTING 1. NO ECHO FROM THE CENTER SPEAKER 5. MICROPHONE VOLUME IS TOO LOW CAUSE: CENTER ECHO is turned off. CAUSE: The mic master volume limiter is set too low. REMEDY: Turn on CENTER ECHO. REMEDY: Adjust to a higher “Max Mic Master Volume.” We design this system in such a way that the echo from the main speakers is independent with that of the center monitor speaker (which helps the singer monitor his/her own singing).

The signal amplifier will stabilize your video quality. If you have a HDTV (Plasma, or LCD) video we recommend you directly connect your source to the video display.
