Flying and Suspension, Are You New to Rigging?

FLYING AND SUSPENSION

JBL SRX700 series offers 4 models with suspendable capabilities: SRX715F, SRX722F, SRX725F and SRX738F. Before attempting to suspend your speakers, read and understand the following safety information.

IMPORTANT SAFETY WARNING!

The information in this section has been assembled from recognized engineering data and is intended for infor- mational purposes only. None of the information in this section should be used without first obtaining competent advice with respect to applicability to a given circumstance. None of the information presented herein is intended as a representation or warranty on the part of JBL. Anyone making use of this information assumes all liability arising from such use.

All information presented herein is based upon materials and practices common to North America and may not directly apply to other countries because of differing material dimensions, specifications, and/or local regulations. Users in other countries should consult with appropriate engineering and regulatory authorities for specific guidelines.

Correct use of all rigging hardware is required for secure system suspension. Careful calculations should always be performed to ensure that all components are used within their working load limits before the array is suspend- ed. Never exceed the maximum recommended load ratings.

Before suspending any speaker system always inspect all components (enclosure, rigging frames, pins, eye- bolts, track fittings, etc.) for cracks, deformations, corrosion, missing, loose or damaged parts that could reduce strength and safety of the array. Do not suspend the speaker until the proper corrective action has been taken. Use only load-rated hardware when suspending SRX700 suspendable versions.

Are You New to Rigging?

If you are new to rigging, you should do the following:

;Read and study JBL Technical Note Volume 1, Number 14: Basic Principles for Suspending Loudspeaker Systems (available at http://www.jblpro.com/pub/technote/tn_v1n14.pdf).

;Know the rules for safe rigging.

;Attend a safe rigging seminar, such as that presented by professionals like Rigging Seminars™ or by Chain Motor Hoist manufacturers like Columbus McKinnon Corp. (manufacturers of the C/M Lodestar).

;Meet and establish a relationship with a licensed mechanical or structural engineer. Get in the habit of asking them questions instead of guessing about their answers. Learn from what they tell you.

;Meet and discuss this aspect of your business with your Insurance Agent.

;Research and understand the codes, practices, and requirements in the venues where you intend to operate your sound system.

General Hardware Information

Any hardware used in an overhead suspension application must be load rated for the intended use. Generally, this type of hardware is available from rigging supply houses; industrial supply catalogs and specialized rigging distributors. Local hardware stores do not usually stock these products. Hardware that is intended for overhead suspension will comply with ASME B30.20 and will be manufactured under product traceability controls.

Compliant hardware will be referenced with a working load limit (WLL) and a traceability code.

Attachment to Structures

A licensed Professional Engineer must approve the placement and method of attachment to the structure prior to the installation of any overhead object. The following performance standards should be provided to the Professional Engineer for design purposes; Uniform Building Code as applicable, Municipal Building Code as applicable, and Seismic Code as applicable.

The installation of the hardware and method of attachment must be carried out in the manner specified by the Professional Engineer. Improper installation may result in damage, injury or death.

SRX700 specifications

The JBL SRX700 series is a line of professional loudspeakers that has been designed for a variety of applications, including live sound reinforcement, installations, and portable use. Known for its high-performance capabilities, the SRX700 series delivers exceptional audio quality and durability, catering to the needs of sound engineers and audio professionals alike.

One of the standout features of the JBL SRX700 series is its advanced transducer technology. Each speaker is equipped with JBL’s proprietary components, including high-performance woofers and compression drivers. This ensures that users experience a wide frequency response with minimal distortion, allowing for crisp highs and deep, powerful lows. The series is designed to deliver a maximum SPL (Sound Pressure Level) that is suitable for large venues, making it an ideal choice for concerts, festivals, and corporate events.

The SRX700 series incorporates JBL’s DuraFlex™ finish, which is a rugged, protective exterior designed to withstand the rigors of touring and installation. The cabinets are made from high-quality plywood, which contributes to the durability of the speakers while reducing unwanted resonance that can color the sound. Each model is also equipped with integrated rigging points, allowing for easy suspension in a variety of configurations.

Another key technology in the SRX700 series is the built-in digital signal processing (DSP). This feature enables users to fine-tune the audio performance through advanced algorithms, providing presets that enhance the acoustics depending on the venue and application. The DSP also includes EQ adjustments, time alignment, and crossover settings, ensuring optimal audio output that meets the specific needs of any sound system.

The series consists of various model options, including both active and passive configurations. The active models come with built-in amplifiers that precisely match the speakers’ specifications, ensuring efficient power management and performance consistency. The passive models allow more flexible integration with existing sound systems, making the SRX700 a versatile choice for diverse sound reinforcement applications.

In conclusion, the JBL SRX700 series combines advanced transducer technology, durable construction, and sophisticated digital signal processing to deliver high-quality audio performance. Its flexibility and reliability make it a popular choice among audio professionals looking to elevate their sound reinforcement capabilities. Whether used for live events or installed systems, the SRX700 series is engineered to meet the demands of even the most discerning listeners.
