OPERATION AND
CONTROLS
3.1 S800
1. Power Switch
Pushing this button is all that is required to turn on the
S800 if it is not part of a Synthesis system and the
Manual On/Auto On switch (rear panel) is in the
Manual On position. If the amplifier is used as part of
a JBL Synthesis System, and the Manual On/Auto
On switch is in the Auto On position, the amplifier
will turn on when the surround processor is activated.
The front panel pushbutton power switch is left in the
ON (in) position..
2. Standby Indicator (red)
This indicator, immediately above the front panel power
switch, will glow red when the amplifier is in the
"standby" mode, whether operating as part of a
Synthesis system or not. When the S800 is in the
"operate" mode, this light will shut off and the blue
"operate" mode indicators will light.
3. Power Indicators (blue)
These indicators will light up when the power amplifier
is in the "operate" mode. Each monitors the operation
of one channel, and will extinguish if that channel’s
protective circuit is activated.
4. Input Jacks (Ch.1 and Ch.2) (see page 11)
If you are using the S800 as a stereo power amplifier,
connect the signal output(s) from the system equalizer
or surround processor to these jacks and set the
Stereo/Mono switch to the Stereo position. If you
are using the S800 in the bridged mode, connect the
subwoofer signal output from the equalizer to the Ch.1
jack only, and put the Stereo/Mono switch in the
Mono position.
5. Stereo/Mono Switch
See paragraph 4 above
6. Speaker Terminals (see page 11)
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. The
terminals for Channel 1 are on the left; those for Channel
2 on the right side as you face the rear panel. Use all four
terminals when using the amplifier in the stereo mode of
operation. 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.
In mono mode, connect the speaker to the center red
terminals only; no connection is made to the
