SECTION 2 : BEFORE YOU BEGIN
The VP Series loudspeakers covered by this manual are not intended for fixed installation in outdoor or high moisture environments. Moisture can damage the speaker cone and surround and cause corrosion of electrical contacts and metal parts. Avoid exposing the speakers to direct moisture. Keep loudspeakers out of extended or intense direct sunlight. The driver suspension will prematurely dry out and finished surfaces may be degraded by long-term exposure to intense ultra-violet (UV) light.
The VP Series loudspeakers can generate considerable energy. When placed on a slippery surface such as polished wood or linoleum, the speaker may move due to its acoustical energy output. Precautions should be taken to assure that the speaker does not fall off a stage or table on which it is placed.
Stand mounting safety precautions
Some VP Series models can be used with an optional stand mount accessory allowing mounting on tripod stands or on a pole over subwoofers. When using stands or poles, be sure to observe the following precautions:
Check the stand or pole specification to be certain the device is designed to support the
weight of the speaker. Observe all safety precautions specified by the manufacturer.
Always verify that the stand (or subwoofer / pole) is placed on a flat, level, and stable surface
and be sure to fully extend the legs of tripod type stands. Position the stand so that the legs do not present a trip hazard.
Route cables so that performers, production crew, and audience will not trip over them and
pull the speaker over.
Inspect the stand (or pole and associated hardware) before each use and do not use
equipment with worn, damaged, or missing parts.
Do not attempt to place more than one VP Series loudspeaker on a stand or pole.  Always be cautious in windy, outdoor conditions. It may be necessary to place additional
weight (i.e. sandbags) on the base of the stand to improve stability. Avoid attaching banners or similar items to any part of a speaker system. Such attachments could act as a sail and topple the system.
Unless you are confident that you can handle the weight of the speaker, ask another person
to help you get it onto the tripod stand or pole.
Hearing damage, prolonged exposure to excessive SPL
VP Series loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause permanent hearing damage to performers, production crew and audience members. Caution should be taken to avoid prolonged exposure to SPL in excess of 90 dB.

Section 4. VP SERIES TRANSDUCERS
2452H-SL High Frequency Compression Driver
JBL’s new 2452H-SL features a lightweight neodymium magnet structure, 4” damped laminate diaphragm and a 1.5” exit. It is designed to deliver crystal-clear sound with superb dynamic range. The 2452H-SL is an 8 Ohm device.
CMCD™ Cone Midrange Compression Drivers (VP7315/64 only)
CMCD technology is more than a simple displacement plug. In addition to providing increased output and lower distortion, this true cone-based compression driver design extends bandwidth (both up and down in frequency) to cover the entire vocal range seamlessly, allowing for better waveguide pattern control by reducing the projection aperture. In addition it improves phase coherency of the midrange signal for clearer, more intelligible audio quality. 8 Ohm device.
For more information, see JBL Tech Note Vol. 1 Number 30, “CMCD Technology”.
Differential Drive® Low Frequency Drivers
JBL’s patented Differential Drive low frequency drivers dramatically reduces driver weight while greatly enhancing all critical performance parameters: frequency response, power output, and distortion. The Differential Drive technology features a unique design with heat sinks integrated into the cast aluminum frame for a highly improved performance to weight ratio. The dual voice coil design places the neodymium magnets inside the voice coil assembly, completing the magnetic circuit without the heavy surrounding steel structure of conventional drivers.

SECTION 5 : ENCLOSURE CARE AND MAINTENANCE
VP Series enclosures are constructed of 5/8-in. multi-ply exterior grade Baltic birch. Each enclosure model is inter­nally braced. The exterior is covered with JBL’s exclusive DuraFlex™ finish.
PAINTING JBL VP SERIES SYSTEM PRODUCTS
Each JBL Professional VP Series system model is readily paintable. The DuraFlex finish provides a lightly textured surface that any household or industrial paint readily adheres to. The result is a speaker enclosure that is able to blend unobtrusively into the decor of any stage set or environment.
Instructions for painting:
1. Prepare the enclosure surface by cleaning and wiping off dust and film with a damp cloth. It may be necessary to use a mild household cleaner to remove grease. Avoid using a cloth that will deteriorate over the textured surface.
2. Apply as many coats of paint as is required. Application can be by rolling, brushing or spraying. Care must be
taken when painting the grille. Avoid any paint or type of application that will clog the open cells in the foam of the front grille. Depending on the type of paint, it may not be wise to spray the grille.
3. For painting systems that are installed in environmentally-hostile locations, it is recommended that an automotive
paint should be used for maximum protection.
Note: for systems that will be transported on a regular basis, oil-based paints or Krylon-type spray paints will give better long-term results than water-based Latex type paints.

SECTION 6 : RIGGING AND SUSPENSION
Safety Precautions
Before attempting to suspend your speakers, read and understand the following safety information.
IMPORTANT RIGGING SAFETY WARNING!
The information in this section has been assembled from recognized engineering data and is intended for informational 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 hardware is required for secure system suspension. Careful calculations should always be performed to ensure that all components are used within their rated workload before the array is suspended. Never exceed maximum recommended load ratings.
Before suspending any speaker system always inspect all components (enclosure, rigging frames, pins, 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 load­rated hardware when suspending VP Series loudspeakers.
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.
Attachment to Structures
A licensed Professional Engineer must approve placement and method of attachment to structures prior to 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, Seismic Code as applicable. Installation of 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.
Rigging Hardware Inspection & Maintenance
Suspension systems are comprised of mechanical devices and, as such, they require regular inspection and routine maintenance to insure proper function ability.
