DISCONNECT CABLES BEFORE MOVING THE SYSTEM To prevent short circuits or breakage of cables, always disconnect cables prior to moving system equipment.

When you power down, the amplifier should ALWAYS be turned off first to avoid the same problems. DO NOT operate at high volume levels or at a level that is uncomfortable. If you experience any discomfort or ringing in the ears, or suspect an hearing loss, you should consult an audiologist. CAUTION!
