black terminals. Wire the "+" terminal of the speaker to the left red terminal, and the "-" terminal of the speaker to the right red terminal.

In bridged mode, speakers connect only to the "hot" (red) amplifier output connectors, and neither can be connected to ground under any circumstances, as damage to the S800 will result.

NOTE: The minimum load impedance that this amplifier can handle safely is two ohms per channel in stereo operation, and four ohms in mono. Using lower impedance loads can damage the unit and will void your warranty!

Use the following chart as a guide to the appropriate gage of wire to use for different amplifier-speaker distances:

Wire Run Length	Rec. Ga.

Up to 20'	16
Up to 50'	14
Up to 100'	12

7. Circuit Breaker/Main Power Switch

The main power switch, located on the rear panel of the S800, is also a circuit breaker. Putting this switch in

the ON position allows the amplifier to enter the "standby" and "operate" modes as controlled by the front panel POWER switch and Manual On/Auto On switches. Should the amplifier be asked to produce more power than its design allows for a prolonged period, or should the S800 draw an amount of current from the AC power source that could damage internal components, the handle of this switch will move to a center position. Reduce the audio level and wait a minute for the circuit breaker to reset, then move it to the OFF, then the ON position. If the handle returns to the center ("tripped") position, service is required; contact your JBL Synthesis dealer.

The S800 was designed to operate reliably under virtu- ally all conditions. Even momentary short circuiting of the output (speaker) connections will not ordinarily damage the output circuitry (although this will activate internal protective circuitry and cause one or more of the front-panel blue LED indicators to extinguish until the circuit resets.)

There are no user-serviceable parts in the S800; there are no fuses accessible from outside the unit. Internal fuses have been incorporated in the S800 to protect it from short circuits and other faults, but these should only be replaced by a qualified technician. In case of one or more inoperative channels, call your dealer to make service arrangements
