Welcome Welcome to the family of discerning sound equipment users who have selected JBL Professional loudspeakers. This User’s 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. Thanks from all of us at JBL Professional.
Before You Begin Important information Before using your SR-X Series speaker system, please review the following for important information on safety and protection of your investment in quality loudspeakers. Rigging / suspending SR-X products SR-X Series speakers are designed for portable applications in which the speakers will be stacked directly on the floor, stage, speaker stands (SR4702X, SR4722X only), other speakers, or a solid, stable platform.
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.
Product Range 2-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.
Product Range 3-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.
Recommended Power The following table shows the recommended amplifier power for SR-X models. For applications in which the ability to reproduce brief, high-power transients is important, an amplifier capable of up to twice the power listed below may be used.
Cable & 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.
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 & Controllers DSC260 Digital System Controller SR-X Series loudspeaker systems may be operated in an optional bi-amplified mode. When used in this optional mode, an external, low-level crossover network is required. JBL Professional offers the DSC260 Digital System Controller for these applications. In addition to the crossover functions, the DSC260 provides signal (time/phase) alignment, equalization, and limiting.
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: DSC controllers, amplifiers and wiring connections. It is very important that you are familiar with the previous sections of this User’s Guide and also the DSC260 system controller.

SR-X/F Flying Versions Suspension or flying speaker systems requires training and expertise. Improper rigging of a flying speaker may result in injury, death, equipment damage, and legal liability. This User Guide is intended to provide a skilled system rigger with resources needed to get the most from the SR-X/F speaker system. This User Guide will not provide the novice with the skills and training needed to safely fly a speaker system.
