CAUTION: NEVER use coiled cords for speaker hookup, even in an emergency.
Coiled guitar-type cords usually have higher internal resis- tance than the speakers themselves. This is due to the light-gauge wire used to keep the coil cords flexible. These cords will prevent most of the power from reaching the speakers. In high power operation, a coil cord can melt causing a fire hazard and possible damage to the amplifier. As a general rule, both straight and coiled gui- tar-type connecting cords make poor speaker cables.
The SPL-6000 can produce enough power output to dam- age electronic equipment connected to its output. Besides being capable of destroying speakers, under certain circum- stances shock and /or fire hazards are possible. High power amplifiers should always be properly applied and used with care in clean and dry environment.
If you have mounted all your sound equipment in a rack or portable case, you can ensure that everything stays calibrat- ed by marking the settings of the necessary controls. Small pointers made from masking tape are visible in dim light and can be removed with alcohol or rubber cement thinner with- out damage to the paint on most front panels including those of the Fender amplifiers. Be sure to check the finish in an inconspicuous place to determine the suitability of any cleanser.
Assuming you are NOT turning all the equipment on at once with a switched power receptacle "strip", be sure to turn on the power amplifier last. This will prevent turn-on "thumps" from the mixer or other pieces of gear that could possibly damage speakers. The reverse logic should also be applied -- turn OFF the amplifier FIRST -- when shut- ting down the system.
The SPL-6000 is timed to turn on the speaker outputs after the amplifier's power supply is fully charged up, thus preventing any turn-on noise. Timing of the amplifier's turn-on circuit is usually sufficient to accommodate all the turn-on anomalies from other pieces of gear in a system, making it acceptable to use a single switched power string in a permanent or semi-permanent system.
CAUTION: The SPL-6000 can draw a lot of AC power. Be sure the AC power source for your AC distribution system has adequate current capability.
In multiple amplifier installations, we recommend sequen- tial turn-on (either manually or via timed relays) to avoid a sudden major drain on the AC line.
You should keep in mind that the severe reduction of power line voltages affects the amount of power you can get FROM the amplifier. If you need to run long AC extension cords, make sure their conductors are as large as practical (small gauge number). Just as smaller diam- eter wire causes speaker lines loss, smaller power lines cause loss. The effect of small AC lines is one of the intermittent clipping under severe conditions.
