General information
A Synthesis One installation incorporates a total of four
power amplifiers; two S800's and two S650A's. Eight of
the ten channels on the S650A's are to be used for
driving the HI frequency and LO frequency inputs on the
left, center, and right speakers, as well as the two side
ambient speakers. Please refer to the connection chart on
the following page; you will find that there are two spare
output channels on the S650A. If desired, these channels
can be connected to the rear outputs on the surround
processor for additional rear ambient speakers. They can
also be used to drive additional speakers in other areas.
The S800's are operated in bridged mode; each drives
one subwoofer. Verify that the subwoofers are connected
ONLY to the red terminals of the amp.
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.
A Synthesis Two or Three installation incorporates a total
of two power amplifiers, one S800 and one S7150 or one
S650A. All channels on the S650 or S7150 are to be used
for driving the left, center, right, and ambient speakers, with
the S800 running in stereo mode to drive the subwoofers.
Use the simplified connection diagrams on the following
pages to help you understand how to connect the S800
amplifier to a JBL Synthesis System. These diagrams are
intended to show the signal flow through the system. For
more detail in making these connections, please refer to
the JBL Synthesis Certified Dealer Installation Manual.
Connect DIN and audio cables between system
components, as shown on the following pages. Make
sure that on all power amplifiers the power switches are
in the depressed (ON) position and that the Auto On/
Manual On switches are in the Auto On position.
Operated in this mode, all of the components will turn on
with one touch of the power button on the surround
processor's remote control.
