8. IN/OUT DIN Jacks
If you are using the amplifier as part of a JBL Synthesis System, it is necessary to use these jacks to interconnect to other system components, so that control signals (power on/off and music/cinema mode switching) can be transmitted from one unit to the next, starting at the surround processor, through the equalizer and amplifiers, and ending at the speakers. Follow the connection diagrams on the following pages corresponding to the appropriate Synthesis system for detailed information regarding these connections. Make connections to these jacks only as shown in the diagrams. If these jacks are used in any other manner, e.g., to control electric screens, the unit can be damaged and the warranty will be void. For specific electrical information on these jacks, contact JBL Synthesis Customer Service at (800)
Do not plug anything into these jacks if you are not using the S7150 with a JBL Synthesis System.
