SECTION 2 :BEFORE YOU BEGIN

The VERTEC® DP Series systems 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 ultraviolet (UV) light.

VERTEC® DP Series Compact Powered Line Array loudspeakers can be suspended with available array frames (P/N VT4887-AF,VT4887-SF) or they can be ground-stacked.These systems can generate considerable energy.When placed on a slippery surface such as polished wood or linoleum,a single 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 scaffold platform on which it is placed. While it is unlikely that a ground-stacked array will move when properly attached to its array frame, precautions should be taken to assure that the array assembly cannot fall from any surface on which it is placed.Hearing damage,prolonged exposure to excessive SPL VERTEC® DP 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 :VERTEC® DP SERIES TRANSDUCERS

2408H High Frequency Compression Driver

JBL’s 2408H features a lightweight neodymium magnet structure,annular polymer diaphragm and a 1”exit.Coupled to a proprietary waveguide engineered to be part of the system’s thermal-transfer mechanism,it is designed to deliver crystal-clear sound with superb dynamic range.The 2408H is an 8 Ohm device.Two are included in eachVT4887ADP system.

2168H-1 Low Frequency Loudspeaker

The 2168H-1 is an 8”transducer engineered with JBL’s patented Differential Drive® technology.These low frequency drivers dramatically reduce driver weight while greatly enhancing all critical performance parameters:frequency response,power output,and distortion.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.8 Ohm device.

For more information, see JBL Tech Note Vol. 1 Number 33, “Differential Drive Transducers”

2269G Ultra Long Excursion, Differential Drive® Low Frequency Drivers

Ultra Long Excursion 460mm (18”) transducer features 2000 watts continuous (AES),8000 watts peak power handling capacity.It’s the latest example of JBL’s patented Differential Drive® dual voice-coil loudspeaker technology,fi tted with dual neodymium magnets,JBL’s exclusiveVented Gap Cooling™,and an ultrarobust composite cone with a peak-to-peak maximum excursion of 89 mm (3.5”).

SECTION 5 :ENCLOSURE CARE AND MAINTENANCE

VERTEC DP Series enclosures are constructed of JBL PlyMax™,an exclusive hybrid engineered-wood technology designed to reduce enclosure weight while offering exceptional panel rigidity with the appropriate acoustical properties.The exterior of each enclosure is covered with JBL’s exclusive DuraFlex™ finish.

PAINTING JBL VERTEC DP SERIES SYSTEM PRODUCTS

Each JBL Professional VERTEC DP 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 wood enclosures (do not paint the JBL DrivePack®):

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 VERTEC® DP Series loudspeakers.
