5. Speaker Terminals Connect the speakers to these terminals, following the normal convention: Wire the �+� side of the speaker to the red terminal, and the ��� side to the black terminal. Wire the speakers with the proper polarity; reversing any speaker�s connections will not damage either the speaker or the amplifier, but will result in poor low-frequency performance and imprecise imaging. WARNING: Terminals marked with the flash symbol are hazardous when live. External wiring connected to those terminals requires installation by trained personnel, and the use of ready-made lead cords. NOTE: The minimum load impedance that this amplifier can handle safely is 8 ohms per channel. Using lower impedance loads can damage the unit and will void your warranty!
6. External Fuses AC mains fuses are located on the back panel of the amplifier. These fuses will not blow unless the amplifier is asked to produce more power than its design allows for a prolonged period or to prevent excessive current draw, which could damage internal components during a fault condition. The amplifier has been designed to operate under virtually all conditions. Even momentary short-circuiting of the output (speaker) connections will not ordinarily damage the output circuitry (although it will activate internal protection circuitry and cause one or more of the front-panel LED indicators to be extinguished until the circuit resets automatically). Fuse Replacement To remove the fuse, turn off the Power switch and disconnect the power plug from the AC mains. Unscrew the fuse holder cap and remove the fuse; install the new fuse and secure the holder cap; and reconnect the AC mains. If after replacing the fuse the unit is inoperative, service is required; contact your JBL Synthesis dealer. WARNING: Always unplug the amplifier from the AC mains before removing any fuse. IMPORTANT: Never install a fuse that has a higher rating than that specified on the back panel of the amplifier or in the owner�s manual.
