POWER AMPLIFIERS From Fender Pro Audio Owner's Manual for SPL-M500 P/N 050253 REV B
Fender Musical Instruments 7975 North Hayden Road, Scottsdale, Arizona 85258 U.S.A. Fender knows the importance of sound reinforcement. From the simple box-top mixer to today's professional touring concert systems, the need to communicate, to make the connection between the performer and the audience is foremost in Fender's mind. Perhaps no other single piece of gear can make or break your band's sound. You see, your sound system is more than just a combination of dials, wires and speakers.

BASIC CONNECTIONS and WIRING Power and audio signal cables are the most common sources of sound system failure. Well made and carefully maintained cables are essential to the reliability of the entire system. If long speaker cables are required, make sure the wire is of sufficient size to transfer all of the available amplifier power to the speakers rather than absorbing power itself. As a rule of thumb, the larger the wire the better (larger wire has smaller "gauge numbers").
The SPL-M500 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 application. 8.
