BEFORE YOU BEGIN Welcome to the family of discerning sound equipment users who have selected JBL Professional loudspeakers. This Users Guide contains important information that will help you get the most from your JBL speakers so please take a few moments to read it and be sure to keep it in a safe place for future reference.
PRODUCT RANGE The SR-X Series consists of 11 popular configurations including subwoofers, front-of-house systems, and stage monitors. SR-X models include these features: • Metalized polyester capacitors are used throughout (instead of cheaper electrolytics) for higher power handling and lower distortion. • "Dual-mode" crossovers can be easily switched from full-range to bi-amplified operation. A tamper-resistant, internal mode selector provides a visible, external indication of the selected mode.
Two-Way Systems SR4722X 12" two-way compact speaker: A great choice for applications where compact size, ease of transport, and speaker stand "mountability" are required. For speech and many music uses, the SR4722X works great by itself. When more bass is needed, team it up with an SR-X Series sub-woofer. A pole-mount socket (35 mm) is provided for stand mounting. SR4725X 15" two-way compact speaker: The 15" two-way system is a favorite for general music and speech applications.
Three-Way Systems SR4732X Dual 12" three-way system: Take the SR4731X, add the high-frequency sizzle of a 2404 UHF driver and you get the ultimate speaker system for very high-level music playback in medium to short throw applications. In combination with the SR4719X subwoofer, this is an unbeatable system for DJ and dance club applications. SR4735X 15" three-way system: For long-throw applications in which the power and additional control of a horn-loaded cone MF driver is desired, choose the SR4735X.

CABLE AND CONNECTIONS Each connector panel incorporates two Neutrik® Speakon® connectors. The second connector facilitates the ability to "loop through" to other SR-X speakers in the system. The diagrams below detail the cable-side connections. Passive Systems & Subs (Parallel Mode) 2+ +1 2- -1 11+ Bi-Amp Systems & Subs (Discrete Mode) 2+ +2 -2 2- +1 -1 11+ Wire Gauges Selection of the appropriate wire gauge is important to system operation.
INPUT PANEL Internal Network Mode Selector All SR-X models are fitted with the internal network mode selector. The ability to select the mode of operation provides the sound system user flexibility in the system configuration, and also permits the system to be upgraded at a later date. By simply removing the input panel and changing the position of a heavy duty connector, the system can be configured as either a bi-amp or a passive system.
INPUT CONFIGURATIONS This section describes the different configurations of Input Connector Panel mode selections. The wiring connections from the Input Panel to the transducers change when the mode selector is moved. Please Note: Each line in the diagrams below represents a pair of wires. (E.g. both +1 and -1 connecting wires.
CROSSOVERS AND CONTROLLERS SR-X series loudspeakers may be operated in bi-amplified mode. In this mode, all crossover components are bypassed (except in the case of the three-way SR4732X and SR4735X) and the voice-coils of the drivers are connected directly to the power amplifier outputs. When operated in this manner, an external, electronic crossover is required. Such crossovers may be cards or modules that can be installed in the power amplifiers or may be separate processors.
SYSTEM CONFIGURATIONS There are many different possible configurations of systems within the JBL SR-X Series. This section shows a selection of key system configurations that will provide a basis for setting up any system, it includes: dbx® DriveRack™ PA controllers, Crown® amplifiers and wiring connections. It is very important that you are familiar with the previous sections of this Users Guide and also the dbx® DriveRack™ PA and Crown® amplifiers.
