SECTION 2 : BEFORE YOU BEGIN
The VRX 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 VRX 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. Make sure the selected AC line voltage is correct.
STAND MOUNTING SAFETY PRECAUTIONS
Some VRX 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 two VRX932LAP 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
VRX 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 3 : INTRODUCTION TO THE VRX932LAP
The VRX932LAP is a powered, two-way, full-range line array speaker system. It is intended for small to mid size venues. The JBL DrivePack DPC-2 amplifier module provides the power and the integrated DSP based input module system optimization and EQ. Since each VRX932LAP has a vertical coverage of 15, line arrays up to 5 x 15 = 75 vertical included angle can be attained. Each cabinet houses 3 HF drivers mounted at equal distance on a waveguide. When combining multiple cabinets, (creating a continuous arc) the distance between the drivers to the adjacent cabinets remains the same creating a constant curvature line source. Furthermore the coverage can be optimized by means of the Array Configuration Selector (ACS), an amplitude shading feature (see page 19 and 20). Built-in rigging hardware, a dual angle pole mount socket and an array frame provide a variety of suspension options.

SECTION 5 : JBL DRIVEPACK TECHNOLOGY
INTRODUCTION TO THE JBL DRIVEPACK DPC-2 INTEGRATED AUDIO SYSTEM
JBL DrivePack equipped loudspeakers are a family of fully integrated audio systems, coupling industry-leading loudspeaker technology to a combination of comprehensive digital signal processing and advanced amplifier technology, perfectly matched to the enclosures to deliver superb audio quality and powerful performance. Designed in cooperation with Crown International, the DCP-2 features Dual Bridged Technology. Each discrete amplifier channel is linked to one voice coil of the Differential Drive loudspeaker. Electrical power transfer to the transducer is optimized for maximum system performance. The DrivePack includes onboard DSP functionality and displays lighted system status indicators during operation.
DRIVEPACK SIGNAL-PROCESSING & AMPLIFICATION UNIT
The DrivePack electronics unit is intended to be used when mounted to a speaker enclosure of 5/8" minimum thickness of wood or composite material and with load impedances of 2 to 4 Ohms for low and mid frequency channels, and 4 to 16 Ohms for the high frequency channel.

OPERATING INSTRUCTIONS

All that is required to get your DP compatible loudspeaker system up and running is to verify that the main panel voltage select switch setting is appropriate for the power in your area, connect an AC power source to the AC Power panel via the Neutrik twist-lock PowerCon inlet connector, and connect a full range line level audio signal to the Input panel via the AUDIO IN XLR connector. The JBL DPC-2 is equipped with a manual select 115V/230V Power Supply and can operate anywhere in the world that has an available 100-120VAC or 200-240VAC power source. Upon initial power-up of the DrivePack, the AC soft-start process will begin and the Blue Power LED illuminates when boot-up is completed.
AMPLIFIER PROTECTION FEATURES THERMAL MANAGEMENT:
JBL DrivePack systems are cooled by Passive Convection. No fans are used in any part of the thermal management system. To maintain efficient cooling it is a good practice to assure open space around the DrivePack units. In the event of excessive exposure to direct sunlight in very hot ambient conditions, it is possible that the unit may overheat and will automatically shut down to protect itself. When its internal temperature has returned to within its operating range it will turn back on. To prevent overheating: ensure adequate cooling and avoid direct exposure of the amplifier panel to direct sunlight by shading it.

OPERATING TEMPERATURE:

The system will remain touchable during quiescent operation and will not provide a burn hazard during any operating condition.

Page 13

AC POWER REQUIREMENTS
JBL DrivePack DPC-2 systems are equipped with a DPC-2 multi-channel Dual-Bridged Technology power amplifier and loudspeaker specific DSP electronics. The system requires appropriate AC power. CAUTION: In compliance with safety agency criteria and proper system operation, it is critical that the system installer observe all electrical safety practices at all times and provide proper earth grounding for all AC Power connections.

AC POWER CORD KIT

120VAC North America NEMA 5-15 Edison type AC plug to PowerCon connector and 240V Europe CEE 7/7 Schuko type AC plug to PowerCon connector cord sets are provided with this JBL DrivePack product. One spare gray Neutrik (P/N NAC3FCB) PowerCon connector is included in the AC Power Cord Set for your convenience to create a pass-through AC power cable. To create a light-duty pass-through cable the system installer may choose to simply cut off the AC plug from one of the provided AC cord sets and replace it with the provided Gray PowerCon AC Outlet connector. Follow the wiring convention indicated in Table 1. NOTE: Tighten set screws to 2.5Nm (1.8lb-ft) torque to prevent opening by hand. CAUTION: In compliance with safety agency criteria and proper system operation, it is critical that the system installer observe all electrical safety practices at all times and provide proper earth grounding for all AC Power connections.
USER-FABRICATED AC POWER DISTRIBUTION
System owners may choose to fabricate or purchase a custom AC Power cable infrastructure optimized for their specific JBL DrivePack system configuration.

Line Voltage Selection: DrivePack DPC-2 amplifier models feature a user-configurable dual-voltage international power supply and is easily set to the appropriate local AC Power Mains voltage supply. A 2-way slide switch is provided to select 100-120VAC or 200-240VAC operation, 50/60Hz. Before you set up your VRX900 Powered series speaker for the first time, verify that the line voltage selector setting is appropriate for the AC Mains supply voltage in your area. Applying 230 VAC to the DPC-2 with the unit set to 115V can cause serious damage.
CHANGING THE AC MAINS SUPPLY VOLTAGE SETTING
Make sure that the speaker is powered off and the AC power cable is disconnected from the speaker. Locate the voltage selector switch next to the blue PowerCon connector on the main control panel. Slide the voltage selector switch to 115V for (100-120V~) or 230V for (220-240V~) range setting as required for your area. After having reconfirmed that the correct voltage is selected, reconnect the blue AC Line Input PowerCon connector and power the unit up. DO NOT UNDER ANY CIRCUMSTANCES OPERATE THE UNIT WITH THE WRONG VOLTAGE SELECTED. DOING SO MAY RESULT IN SERIOUS DAMAGE TO YOUR SPEAKER SYSTEM WHICH WILL NOT BE COVERED BY WARRANTY. Line Voltage Tolerance: The amp will operate normally (with expected de-rating in power output during low line conditions) over a range of 100-120VAC +/-10% or 200-240VAC +/-10% AC input voltage. The amp will shut down for voltages below nominal line and self protect for over-voltage beyond 15% nominal line. CAUTION: Continuous voltages 10% beyond high line at either 120VAC or 240VAC operation ranges can disrupt performance of the JBL DrivePack! To avoid activation of amplifier low line/ high line protection which will interrupt audio performance, the system operator should maintain AC supply voltages within the rated voltage windows.

Page 15

VRX932LAP INPUT PANEL
The VRX932LAP input panel features analog audio inputs and sophisticated onboard digital signal processing technology. Precision Bandpass limiting, pre-equalization filters and automatic self-protection functions ensure maximum performance. JBL engineers have calibrated the DSP speaker management and limiter parameters to ensure smooth phase response and transfer function.

CONTROLS

1.& 2. HF OUTPUT LEVEL (ACS) Push-button DSP preset selection switches for Amplitude Shading (ACS) and for adjusting tonal balance for different system configurations. When set in the -3dB position, the High Frequency level is reduced by -3dB from nominal. This selection is recommended if only a single speaker is employed. See the ACS section (page 19 & 20) for more information. 3. ATTENUATION Detented rotary input sensitivity control attenuates level in 0.5 dB steps. The Input Sensitivity is +4 dBu nominal (+20 dBu clip) with the control fully counter clockwise, and -10 dBV nominal (+4 dBu clip) with the control fully clockwise. (Note: Professional mixing boards with XLR outputs should use the fully counterclockwise position as start ing point. Whereas semi-professional equipment with 1/4 inch jacks, RCA connectors and unbalanced sources should start at the middle position - watch for clipping (peak LED)! 4. RESET Press to reset line voltage circuit breaker. 5. LINE SELECT Two-position slide switch, set to 115V position for (100-120V~) or 230V position for (220-240V~) operation.

SINGLE VRX932LAP

A single VRX932LAP may be used on a tripod stand (JBL SS2-BK) or on a pole (JBL SS4-BK) over its companion subwoofer the VRX918SP. The use of a subwoofer is recommended for applications requiring more low-frequency power and extension. Usually, the Array Configuration Selector (ACS) switches on the input panel should be set to the Short Throw (-3 dB) position when a single speaker is used. The VRX932LAP includes a dual angle 36 mm pole mount socket. By selecting the appropriate pole socket and adjusting the height of the tripod or pole, optimum coverage may be achieved. Ideally, the audience should not be able to see either the bottom or the top surfaces of the speaker. This will ensure that all listeners are within the included coverage angle of the loudspeaker. The rear pole-socket will position the speaker with the baffle 2.5 to the floor while the forward socket will position the speaker with the baffle angled down by 15. System illustration shows the available JBL SS2-BK tripod stand.

Page 22

DUAL VRX932LAP
Unlike most conventional speakers, the VRX932LAP is designed so that a pair of speakers may be safely mounted onto a pole or tripod stand. For most applications, the forward socket of the dual angle pole socket will be used. This will tilt the lower of the two speakers at a 15 down-angle (providing coverage of the near listeners) while the upper speaker will face straight out (covering the more distant areas). Ideally, the listeners should not be able to see either the bottom or the top surfaces of the two-speaker array. Usually, the Array Configuration Selector (ACS) switches on the lower speaker's input panel should be set to the Short Throw (-3 dB) position while the upper speaker will be set to either Short Throw (-3 dB) or Mid Throw (0 dB). Place the speakers on the pole or tripod one at a time. Be sure to lock the two speakers together using the integral rigging hardware (see below). System illustration shows available JBL SS4-BK speaker pole and SRX718S subwoofers. Do not stack more than two VRX932LAP speakers on a pole.
LOCKING (2) VRX932LAP LOUDSPEAKERS TOGETHER

MAXIMUM ARRAY SIZE
There are three variations of the VRX array frame. The VRX-AF supersedes the VRX932LA-AF. The VRX-SMAF is solely intended for use with the VRX928LA and VRX915S. Before suspending a VRX array, determine which version of the array frame you have and consult the table below to determine the maximum number of speakers that may be safely suspended. The subwoofers must always be at the top of the array. NOTE: For combination of passive and powered speaker systems use the table for powered speakers (VRX932LAP and VRX918SP).

VRX-AF ARRAY FRAME

The following table defines the maximum number of speakers that may be suspended using the VRX-AF frame. A minimum design factor of 7:1 is maintained for all speaker configurations at or below those indicated in the table. Maximum number of VRX918SP in array Maximum number of VRX932LAP in array 4 0
