Connecting the Speaker to the Rest of Your System

CONNECTING THE SPEAKER TO THE REST OF YOUR SYSTEM

INPUT/OUTPUT ASSIGNMENTS WITH PASSIVE CROSSOVER

The SDEC-3000 supports up to 7.1 input with up to 7.1 output. The input and output assignments are as described in the below chart. You must make the correct connections from the surround processor output to the amplifier input for the system to work correctly. Please refer to the connection diagram for more information.

The correct Synthesis Interconnect kit includes all the necessary connections for using the SDEC in the Synthesis sys- tem. Please be sure to order the S3000IC for use with SDEC-3000 and S4000IC for use with SDEC-4000. Retrofit kits are also available. Please contact JBL Synthesis Technical Support for more information at (888) 691-4171 (USA only).

CONNECTION NOTES

•Please follow the wiring diagram and the Input/Output Assignments chart for correct connections.

•You will need to use the Ethernet network port on the rear panel of the unit for the final calibration process. You can use a crossover network cable if you plan to connect directly to the SDEC-3000 from a computer. Alternatively, you can connect the SDEC-3000 through any standard Ethernet hub.

•When using the SDP-40 processor, make sure the subwoofer (in speaker setup) is set to Mono output and connect to the Subwoofer Left output. Do not use the LFE output.
