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-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.

The PRX500 Series power amplifier

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.

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-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.

1 - EQ BOOST / FLAT: When set in the “FLAT” position, frequency response is linear and unaltered.When “Boost” is selected, internal equalization is applied to enhance low frequency and high frequency response. “FLAT” will provide greater accuracy of reproduced music, higher speech intelligibility and maximum overall level. “BOOST” is particularly useful at lower levels to enhance prerecorded music. The feature provides flexibility without the need to use an external equalizer. The chart

(at right) shows the effect of the “BOOST” setting.

MAIN/MONITOR (PRX512M ONLY): On the PRX512M: Switching between “MAIN” and “MONITOR” optimizes the system for use as either a main full-range system, or a stage monitor.

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.

Features

1 - XOVER IN / OUT: Pressing this button engages a high-pass filter 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.

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 a full-range or high-passed signal. dependent on the setting of the “XOVER” switch. In addition to connecting a full-range system 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.

20

The following levels should be used as a reference if you know the maximum output in dBu of the source connected to the system’s input. For each position stated below there is an input signal level in dBu that is required to deliver absolute maximum output of the system.

LINE
Level Position	Input Level Required To Deliver Maximum Output
Full “on”	+10 dBu
			+17
3 o’clock	+12 dBu
		+28	+12
12 o’clock	+17 dBu
9 o’clock	+28 dBu	0	+10
MIC
Level Position	Input Level Required To Deliver Maximum Output
Full “on”	-25 dBu
			-18
3 o’clock	-23 dBu
		-7	-23
12 o’clock	-18 dBu
9 o’clock	-7 dBu	0	-25

SETTING THE GAIN

Only a properly setup system will guarantee maximum performance with a minimum of distortion and feedback. (This is as true for self powered systems as it is for passive systems). An easy to rule to follow is:” Everything should clip at once.”

Following these simple steps will ensure you are getting the optimum performance out of your complete system.

1.Once the source has been connected to the input of your mixer, adjust the input sensitivity (or trim) so that the highest input levels are set to just before clip (or when the input LED just starts to flicker).

2.Position the channel fader for that input to 0 dB.

3.Position the Master output fader to 0 dB.

4.With the “Mic/Line” button set to “Line” (because the system is receiving a line level signal, or commonly called a +4 dB signal), set the “Level” control to the 12 o’clock position, and adjust until the “overload” LED just begins to flicker.

APPLICATION EXAMPLES

Basic Sound Reinforcement System

This is a very basic sound system. PRX500 series speakers allow the direct connection of sound sources, without the need for extra mixer or pre-amplifier. The XLR or 1/4 inch input jack provides versatility and cabling options and the mic/line input sensitivity selector switch optimizes the speaker gain for the input source. Additional speakers may be connected (daisy chained together) in mono mode.

Music Playback Reinforcement With Subwoofer (PRX512M Pole Mounted On A PRX518S)

This is a very powerful, but flexible combination. The subwoofer provides the extra low frequency extension and also serves as the base for the pole mount. The compact 12 inch satellite system, PRX512M is a perfect match to the subwoofer.

From the master outputs of your mixer route the wires to the subwoofer first and select the x-over in (high-pass) option. Route the cable form the subwoofer output connector to the top. Reduce the volume of subwoofers. Adjust the volume for the top to desired levels and match the subwoofer volume to achieve desired results. This will provide a well balanced LF performance for the system.

Live Performance Or Music Playback Reinforcement System With Stage Monitors (PRX535 And PRX512M)

This is an ideal system when wide coverage and good directivity is required, specifically in highly reverberant rooms. The horn loaded PRX535 3-way system will control the propagation of the sound much better than a conventional 2-way system. The more directional or controlled the sound is the more independent the system becomes from the room acoustics present, resulting in a much clearer sound. The PRX535’s full low end is an additional advantage when no subs are used. The PRX512M’s are set to the “monitor” EQ setting.

Large Live Performance Or Music Playback Reinforcement System With Stage Monitor (4 x PRX518S, 4 x PRX525 And 2 x PRX512M)

For larger crowds in and outdoors, a flexible system like this will deliver excellent results. The dual 15 inch PRX525 delivers mighty bottom end and crisp highs. The combination of extra PRX518S subwoofers gives it a even more thunderous low end. The PRX525’s can be arrayed as pair of two’s each side for a wider coverage and some extra SPL (extremely useful in outdoor applications).

REFERENCE

Balanced vs. Unbalanced Lines

Your PRX500 series can accept either type of input. There are two basic types of audio system interconnections for audio signals: Balanced and Unbalanced.

Balanced Lines

In audio, a balanced line is a three-conductor system in which the two signal wires carry an equal, but opposite voltage with respect to the ground wire. The ground wire acts only as a shield and does not carry any audio signal current. Outside interference (such as RFI - Radio Frequency Interference) is either shielded from the internal signal conductor, or if it gets into the cable is cancelled out by the opposite signals at the receiving end. Balanced connections are preferred for any longer cable runs.

Unbalanced Lines

Unbalanced cable is a two-wire system where the shield (ground wire) acts as one of the current carrying signal conductors. The center conductor enclosed by the shield is commonly known as the “hot” conductor. Unbalanced audio cables do not reject noise as well as balanced lines. Unbalanced lines are typical in home hi-fi type systems and on the outputs of electronic musical instruments. These work well if the distance between the components is short, the signal level is relatively high and all of the electronics used in the system are plugged into the same AC service.
