5. Speaker Terminals
Connect the speakers to these terminals, following the nor-
mal 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 protec-
tion 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 discon-
nect 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.
