[. . . ] If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits, as contact with them might be fatal. [. . . ] Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous voltage or other hazards. When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or that have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock or other hazards. Upon completion of any service or repairs to this product, ask the service technician to perform safety checks to determine that the product is in proper operating condition. The product should be mounted to a wall or ceiling only as recommended by the manufacturer. Figure A. Example of Antenna Grounding as per National Electrical Code ANSI/NFPA 70 1. 8. Note to CATV system installer: This reminder is provided to call the CATV system installer's attention to Article 820-22 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical. 3 SDEC3000. 4500. om. qxd 4/16/09 10:06 AM Page 4 INTRODUCTION AND FEATURES INTRODUCTION Congratulations on your purchase of this JBL Synthesis® SDEC Digital Equalizer!You have chosen a product that embodies the best of what JBL, Inc. , has discovered about the emotional power of audio reproduction in more than sixty years of preeminence in the field. This Digital Equalizer has been designed and crafted to provide the user with a high level of sonic performance. Special attention has been paid to minimize the number of components in the audio signal path, resulting in extremely low distortion, excellent transient response and wide dynamic range. Synthesis® products set new benchmarks in audio technology, and, when used as part of a complete JBL Synthesis system, will bring the ambience and acoustics of some of the world's greatest concert halls and theaters into your home. 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. 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. You should use them in pairs so that you either have two or four subwoofers. · You must connect the SDEC-4500P and the SDEC-4500X using the BlueLink connection, using an Ethernet network patch cable, Cat. · 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. [. . . ] 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. 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. METHOD TWO: WITH A COMPUTER While online and in Operate mode from within London ArchitectTM or when using the Java remote, select the appropriate speaker configuration as your installation requires. The software will automatically configure the outputs correctly. 8 SDEC3000. 4500. om. qxd 4/16/09 10:06 AM Page 9 INPUT/OUTPUT ASSIGNMENTS SDEC-4500 WITH BI-AMPLIFIED FRONT SPEAKERS This configuration requires the selection of bi-amplified operation, as noted on page 8.
