INPUT/OUTPUT ASSIGNMENTS

SDEC-4000

The SDEC-4000 comprises two units. Both the SDEC-4000P and SDEC-4000X are required for the digital equalizer to function properly in the Synthesis system. Please be sure to connect both units correctly according to the Input/Output Assignments chart.

The correct Synthesis Interconnect kit includes all the necessary connections for using the SDEC in the Synthesis System. 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).

The SDEC-4000 is capable of processing up to 12 inputs and up to 20 outputs. Depending on the type and number of outputs will determine which connections you should use to connect the SDEC to the rest of your system. Please refer to the connection diagram for more information.

CONNECTION NOTES

•The SDEC-4000 can process two outputs for the front left, center and right channels to output to an amplifier for a Bi-amplified system. There are discrete outputs for a single high-frequency horn speaker (SAM1HF) and low-frequency (SAM2LF) speakers. These outputs can only be used with speakers designed to be used with an external crossover. Do not use the SDEC Digital Equalizer for any speakers other than the recommended Synthesis speaker packages.

•There are two pairs of outputs for side speakers. If you are only using one pair of side speakers you may leave the second pair of outputs with no connection. If you are using a second pair of side speakers, you should connect the pair closest to the front speakers to output 1 and the pair closest to the rear speakers to output 2.

•There are up to four subwoofer outputs. You should use them in pairs so that you either have two or four subwoofers. All Synthesis systems are designed for at least two subwoofers.

•You must connect the SDEC-4000P and the SDEC-4000X using the CobraNet connection, using an Ethernet network crossover cable, Cat. 5e minimum.

•The two units must be connected to an Ethernet network hub for the final calibration process. Both units need to be connected to the same hub or router, and an open port needs to be accessible for the calibration computer.

•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.
