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) 336-4JBL.

Do not plug anything into these jacks if you are not using the S7150 with a JBL Synthesis System.

9. Speaker Mode Control Connectors

The front left and front right speakers are switched between Music and Cinema modes by signals present at both the DIN connectors (as described in the previous paragraph) AND the 2-conductor connectors shown at (9).

CONTROLS

The installer may find it preferable to use 2-conductor wire (18 gage recommended) rather than long multi- conductor DIN cables for the mode-switching connection between the S7150 and these two speakers. Adapters supplied with the S7150 are used at the speaker end of the wire to allow connection to the speakers' DIN input connectors. Proper polarity must be observed as shown in the wiring diagrams; reverse the connections at one end of the wire if the speaker(s) do not switch modes (from horn (Cinema) to tweeter (Music)).

Note that 5-conductor DIN cables MUST be used between all other components to allow correct power and mode switching and that the same warning as in

(8)applies here; do not attempt to use these jacks to control anything other than the mode-switching function of Synthesis speakers, as this may damage the S7150 and will void the warranty.

10. AC Inlet

Your S7150 is shipped with an IEC-type removable power cord that mates with the AC inlet on the rear panel. To ensure proper operation, use the supplied power cord. This amplifier is NOT a multi-voltage unit; using a power cord with a different connection to the AC wall receptacle will void the warranty.
