Precautions AVOID EXCESSIVE HEAT, HUMIDITY, DUST AND VIBRATION When choosing a location for your speakers, avoid the following: • Direct sunlight, high temperatures (such as near heat- ers), or excessively low temperatures. • High humidity. • Areas subject to excessive dust accumulation and vibra- tion. • Non-level or unstable surfaces. HOW TO POWER UP YOUR SOUND SYSTEM To avoid damage to your speakers and other parts of your system, when you turn on your system, ALWAYS turn the power amp on last! This will avoid loud, damaging pops that will annoy your audience, and blow your speakers. When you power down, the amplifier should ALWAYS be turned off first to avoid the same problems. MAKE SURE THE POWER IS OFF BEFORE MAKING OR REMOVING CONNECTIONS Always turn the power switches of system components OFF prior to connecting or disconnecting cables. Failure to do so may result in damage to speakers as well as to connected equipment. DISCONNECT CABLES BEFORE MOVING THE SYSTEM To prevent short circuits or breakage of cables, always disconnect cables prior to moving system equipment. MATCH CONNECTOR POLARITY When using two or more speaker systems, be sure match the polarity (+/-) of the speaker system connectors to those at the amplifier. If the polarities do not match, the sounds produced by the speakers will interfere with each other, making it impossible to achieve a well-balanced sound field. KEEP THIS OWNER'S MANUAL IN A SAFE PLACE FOR FUTURE REFERENCE To protect your speakers When choosing a power amplifier to use with your speakers, make sure that its power output matches the speakers' power capacity (refer to the Specifications on page 5). Even if the amplifier's power output is lower than the speakers' PGM (program) power capacity, the speakers may be damaged when clipping of a high input signal occurs. The following may cause damage to speakers: • Feedback caused when using a microphone. • Continuous high sound pressure level produced by electronic instruments. • Continuous high-power output distorted signals. • Popping noises caused by turning on equipment, or by connecting or disconnecting system components while the amplifier is turned on. ʵʵ
