Fender Musical Instruments 7975 North Hayden Road, Scottsdale, Arizona 85258 U.S.A. A Message from the Chairman At Fender, we know the importance of sound reinforcement. From the simple box-top powered mixer to today’s touring concert systems, the need to communicate to make the connection between the performer and the audience is foremost in our mind. Perhaps no other piece of gear can make or break your message or your band’s sound than your sound reinforcement gear.

SPEAKER WIRING AND CONNECTIONS Parallel or series are the two basic ways which multiple speakers can be connected to a single power amplifier. When speakers are connected in parallel, their combined impedance decreases. For speakers wired in series the opposite is true, their combined impedance increases. Thus, when speakers are wired in series, higher impedance speakers in the series draw more power from the amplifier than do speakers in the series with lower impedances.
Mk III SERIES SPEAKER CONNECTIONS SETUP SUGGESTIONS In normal operation (using the passive internal crossover), the 1/4" jacks and the Speakon ™ Connectors are wired in parallel allowing any one of the connectors to be used as an input and any other as an output. This allows "daisy chaining" of multiple loudspeakers, eliminating the need for several long, cumbersome runs of speaker cable.
BI-AMP OPERATION UNPOWERED MIXER For versatility and increased headroom, some users may choose to use an active electronic crossover / processor, such as the Fender PCN-2 or PCN-4, with the system. The electronic crossover takes the place of the internal crossover of the speaker system. The "Normal / Bi-Amp" switch on the back of the cabinet must be set to the "Bi-Amp" position.
