PRECAUTIONS

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-termexposure to intenseultra-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.

The PRX500 Series power amplifier

AC Power Requirements

Standard PRX500 series speaker systems are equipped with a multi-channeCrownClass-Dpower 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-muteto 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.

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.

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.

Introduction to the PRX500 series

PRX512M

PRX518S

PRX515

PRX525

PRX535

Thank you for choosing the JBL PRX500 series self-poweredPA loudspeakers. There are five models in the series, fourfull-rangesystems 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-dutyfoam 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 polypropyleneend-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.

2 - INPUT MIC / LINE: Allows the selection of different input sensitivities to permit the connection of many different sources, with or without the use of a mixer or external microphone preamplifier. See “Setting Input Sensitivity” on page 18.

3 - LEVEL: Sound level adjustment. With the input in the “MIC” position the level can be adjusted over a large range. In the “LINE” position most typical applications will require that the level control is set at 12 o’clock. (More details are outlined in “Setting the Input Sensitivity” and “Setting the Gain”).

6 - POWER SWITCH: Turns the power on. The illuminated logo in the front of the speaker serves also as a power “on” indicator.

7- LINE SELECT: Allows the user selection for different local voltage ratings.

8- AC LINE INPUT: Standard IEC AC mains input connector.

Indicators

4- SIGNAL: Signal indicator. The green LED illuminates when a signal is present.

5- LIMIT: Protection indicator. The red LED illuminates when the system overload protection is active.

Connectors

9- XLR: Female balanced XLR and 1/4 inch phone jack combo balanced input connector.

10-XLR : Male balanced XLR output connector. This connector provides afull-rangesignal which can be daisy

chained to another speaker.

Features

1 - XOVER IN / OUT: Pressing this button engages ahigh-passfilter at 110 Hz. This 4th order active filter allows a smooth transition between the subwoofer and a full range speaker connected to the output connector.

2 - POLARITY INVERT: Allows you to set the polarity of the subwoofer to either 0° (no change) or 180° (inverse polarity). The correct polarity setting will produce the best blend between the subwoofer and the fullrange speaker and the strongest perceived bass response at the listening position. This is especially useful when the subwoofer is placed at a different distance from the listening position than the fullrange speakers. If the bass response seems weak, try inverting the polarity.

3 - LEVEL: Sound level adjustment. The 12 o’clock position is a good starting point for most usages. Once thefull-rangesystem has been connected the level can be varied to match and deliver the desired balance (for details see Setting the Gain on page 21).

6- POWER SWITCH: Turns the power on. Power “on” status is indicated with the illumination of the logo on the grille.

7- LINE SELECT: Allows the user selection for different local voltage ratings.

8- AC LINE INPUT: Standard IEC AC mains input connector.

Indicators

4- SIGNAL: Signal indicator. The green LED illuminates when a signal is present at the input connector.

5- OVERLOAD: The red LED illuminates when the system overload protection is active. If the input signal is too

strong or the “LEVEL” control set too high, the red LED will illuminate constantly. Illumination of the “OVERLOAD” LED can be avoided by reducing the input level or turning down the “LEVEL” control to the point at which the red LED occasionally flickers.

Connectors

9 & 11 - XLR: 1/4 inch phone jack balanced input connector. (see Reference section page 26 for information).

10 & 12 - XLR: Male balanced output connector. This connector provides afull-rangeorhigh-passedsignal. dependent on the setting of the “XOVER” switch. In addition to connecting afull-rangesystem to the output, it’s also possible to daisy chain subwoofers together.

Note 3: A single subwoofer can be used with a stereo source. The integral differential circuits sums the low frequency information from the left and right channel to a mono signal, ready for reproduction by the subwoofer.

SETTING THE INPUT SENSITIVITY

PRX500 series systems have been designed to allow the connection of a variety of sources. This provides a great deal of versatility, especially with the PRX512M and PRX515, as a microphone or instrument can be connected directly to the input. Low levels output from consumer products like MP3 and CD players, can also be accommodated.

There are two user selectable gain or input sensitivity ranges: Mic and Line. For the majority of applications, the system will be receiving a signal from a mixer, equalizer of other professional grade product. In this case “Line” should be selected and the “LEVEL” adjusted to the 12 o’clock position indicated by the +4 dB region. The “LEVEL”control can then be trimmed to optimize the performance of the system (see Setting The Gain).

LINE

When a microphone, instrument or other consumer product is connected to the system, first ensure that the “LEVEL” control is at its minimum, anti-clockwise,OFF position. Then select the “Mic” input sensitivity and slowly increase the level. If the “overload” LED illuminates you should back the level down again. If the “overload” LED illuminates and the “LEVEL” control is barely cracked open then you should try selecting the “LINE” input sensitivity range.

MIC

WARNING: SELECTING THE “MIC” POSITION WITH THE LEVEL CONTROL IN ANY POSITION OTHER THAN THE “OFF” POSITION MAY RESULT IN EXTREMELY HIGH SPLs.
