INPUT/OUTPUT ASSIGNMENTS

SDEC-4500

The SDEC-4500 comprises two units. Both the SDEC-4500P and SDEC-4500X 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 on page 9.

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 or S3000XLRIC for use with SDEC-3000 and S4000IC or S4500XLRIC for use with SDEC-4500. Retrofit kits are also available. Please contact JBL Synthesis Technical Support for more information at 516.594.0300 (USA only).

The SDEC-4500 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-4500 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 three pairs of outputs for side speakers. If you are only using one pair of side speakers, then you may leave the second or third pair of outputs with no connection. If you are using a second or third pair of side speakers, then you should connect the pair closest to the front speakers to Output 1, the pair in the middle of the room to Output 2, and the pair closest to the rear speakers to Output 3.

•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-4500P and the SDEC-4500X using the BlueLink connection, using an Ethernet network patch 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-40HD processor, make sure the subwoofer (in speaker setup) is set to Mono output and con- nect to the Subwoofer Left output.

SELECTING FULL-RANGE OR BI-AMPED CONFIGURATION

There are two ways to select between bi-amped or full-range LCR operation.

Please note: Only Method One can be done on the control ports (without a computer). Method Two requires a computer running the appropriate configuration software. Please contact JBL Synthesis Technical Support for more information.

METHOD ONE: WITHOUT A COMPUTER

Full Range: With the SDEC powered up and running, connect Control Input 1 to “C” (common) on the back of

the unit for full range. This is a temporary contact and should not be left in place.

METHOD TWO: WITH A COMPUTER

Bi-Amped:With the SDEC powered up and running, connect Control Input 2 to “C” for bi-amped. This is

a temporary connection and should not be

left in place.

While online and in Operate mode from within London Architect™ or when using the Java remote, select the appropriate speaker configuration as your installation requires. The software will automatically configure the outputs correctly.
