SECTION 2 : BEFORE YOU BEGIN

The VERTEC®DP Series systems covered by this manual are not intended for xed 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 nished surfaces may be degraded by long-term exposure to intense ultra-

violet (UV) light.

VERTEC® DP Series Midsize Powered Line Array loudspeakers can be suspended with available

array frames (P/N VT4888-AF, VT4888-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) sufcient 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.

2431H High Frequency Compression Driver

JBL’s 2431H features a lightweight neodymium magnet structure, 3”

diaphragm and 1.5” 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 2431H is an

8 Ohm device. Two are included in each VT4888DP system.

2106HPL Midrange Loudspeaker

The low distortion, high output design of the VERTEC mid-range driver

ensures superb  delity and articulation in the critical midrange

frequencies. The VT4888DP’s four 2106HPL 138 mm (5.5 in) with 50

mm (2 in) dia. voice coils employ JBL’s exclusive Differential Drive®

cone transducer technology for lower weight and higher output. The

highly ef cient cooling characteristics of the mid-range drivers ensure

lower operating temperatures, greatly improved power compression

characteristics and lower harmonic distortion. 8 Ohm device.

2262H Low Frequency Loudspeaker

The 2262H is a 12” 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”

2266H Long Excursion, Differential Drive®

Low Frequency Driver

Long Excursion 381mm (15”) transducer features 1200 watts continuous

(AES), 4800 watts peak power handling capacity. It’s the latest example

of JBL’s patented Differential Drive® Neodymium Magnet, dual voice-coil

loudspeaker technology, high peak to peak excursion capabilities, and

JBL’s exclusive Vented Gap Cooling™.

8 Ohm device.
