4.0 INTERCONNECTIONS IN SYNTHESIS SYSTEMS
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.
