Care And Cleaning

PRX500 series systems may be cleaned with a dry cloth. Do not get moisture into any of the openings in the system. Ensure that the system is unplugged from the AC outlet before cleaning. In the event the DuraFlex finish is damaged a touch up kit can be obtained from JBL Professional (part number 363972-001).

THIS APPARATUS CONTAINS POTENTIALLY LETHAL VOLTAGES. TO PREVENT ELECTRIC SHOCK OR HAZARD, DO NOT REMOVE CHASSIS, INPUT MODULE OR AC INPUT COVERS. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

IMPORTANT SAFETY INSTRUCTIONS

The PRX500 series speakers covered by this manual are not intended for fixed installation and 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 speakers 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. PRX500 series speakers 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 PRX500 series models include a 36 mm receptacle cup to allow 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 and topple the speakers 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 PRX500 series speaker 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

PRX500 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.

• Increase the separation between the equipment and reliever.

• Connect the equipment into an outlet on a circuit different from that to which the reliever is connected.

• Consult the dealer or an experienced radio / TV technician for help.

Changing Voltage

Your PRX500 series speaker will typically be set at the factory to accommodate the power mains voltage in your area. Before you set up your PRX500 series speaker for the first time it is a good idea to verify that the setting of the selector is appropriate for the power in your area. In the event that you do need to change the voltage:

• Make sure that the speaker is powered off and the AC is disconnected from the speaker.

• Directly above the male IEC connector on the speaker is a voltage selector. Just slide the switch to the appropriate setting.

• Set the voltage selector switch to the 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 AC (IEC 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.

CLASS 2 WIRING

AC Power Requirements

Standard PRX500 series speaker systems are equipped with a multi-channe Crown Class-D power amplifier and loudspeaker specific DSP electronics and require appropriate AC power. Before plugging a PRX500 speaker into an outlet ensure that it is able to provide the appropriate AC power as set on the speaker.

A robust AC supply is necessary for maximum performance. If the supply is too weak the bass performance may be affected and if it sags (drops) too much the system may self-mute to protect itself. As soon as the appropriate AC supply is restored it will continue to operate. Plugging multiple systems into the same outlet and long extension cord runs may affect the AC supply to the systems.

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.

Powering Up

The main power switch is located on the input panel on the back of the enclosure. Always ensure that the speaker system is the last thing you power up, and the first thing to turn off when operating your complete PA system. If speaker systems are daisy chained together always turn off the last system in the chain first. Power “on” is indicated by the illumination of the logo on the front of the enclosure.

Operating Temperature

The design of the Crown amplifier is such that it is very energy efficient and as a result does not get really hot. In the rare event that it does get too hot it will automatically shut down to protect itself. When its temperature has returned to within its operating range it will turn back on. A Condition under which this may occur is when the system is operated in very high ambient temperatures and the heat sink on the rear of the enclosure is in direct sunlight. Always ensure adequate cooling and appropriate shade.

Thank you for choosing the JBL PRX500 series self-powered PA loudspeakers. There are five models in the series, four full-range systems and one subwoofer. All are powered by integrated digital power amplifiers developed by Crown, the most trusted name in professional sound reinforcement power amplification. In addition to Crown power amplifiers, the systems are equipped with sophisticated DSP for EQ, crossover, system control and protection. Engineered and manufactured by JBL Professional with precision and care, your PRX500 series speaker will provide you with many years of flawless performance. To ensure you are always receiving optimum performance we encourage you to review this user’s guide completely before hooking up your new system.

In addition to the high performance light weight Crown amplifier, PRX500 series utilizes the latest in JBL transducer technology. New 400 watt neodymium Differential Drive

transducers not only provide high sound pressure levels with minimum distortion and power compression, but they are also incredibly light. Combined together in highly engineered enclosures, PRX500 series speaker systems deliver the highest performance to weight ratio in the class – portable PA that’s actually portable.

All PRX500 systems are built road tough; covered with JBL’s DuraFlex™, one of the most durable finishes ever created for a speaker and protected by heavy-duty foam backed steel grilles. The foam backing not only looks excellent but it stops direct liquid intrusion and it does not affect the acoustics. The larger systems have an extra layer of protection from the road in the form of tough polypropylene end-caps. These are independent of the acoustic enclosure so in the event of really tough knocks the speaker’s performance will not suffer.

Single Box On A Pole Coverage

The PRX512M features a dual angle pole socket this provides flexibility in aiming the speaker. As a guide line, the speaker should be positioned so that the audience cannot see the top or bottom panels of the speaker. The PRX515 and PRX535 also feature a pole mount of the ‘single’ socket variety. When using stands or poles, be sure to observe the precautions as stated in the “Precautions” section of the manual.
