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.
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.
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.

USA AC LINE INPUT Equipped with Differential Drive® Transducer Technology U.S. PATENT 5,748,760 Other U.S.
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.

3 - LEVEL: Sound level adjustment. The 12 o’clock position is a good starting point for most usages. Once the full-range system 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.
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.
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.
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.
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.
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.
CABLES AND CONNECTORS XLR/F to XLR/M Microphone Cable The standard cable for interconnection of microphone and line level signal in professional audio systems. • Microphone to mixer • Microphone to PRX500 direct input • Professional audio mixer to PRX500 • Daisy chaining PRX500 speakers TRS (balanced) 1/4 inch phone jack to XLR/M For connecting balanced devices with 1/4 inch phone and maybe used interchangeably.
TROUBLESHOOTING Symptom Likely Cause No sound. Speaker not connected to active AC power. Verify that speaker is connected and that the circuit is on. Switch on power and verify that illuminated logo is on. Speaker power Cable is faulty or improperly Connected. • Re-seat the power cable at both ends. • Substitute a known-good power cable. Blown fuse. • Replace the fuse with the specified value. • Take your speaker to a competent servicer.
Noise or hiss heard at output Noisy Source Device Disconnect the devices that are connected to your speaker one at a time. If the noise goes away, the problem is with the source or the connecting cable. Hum or Buzz that increases or decreases when the mixer level controls are moved. Improper A/C ground or faulty equipment connect to mixer input Disconnect or mute channels one at a time to isolate the problem. Refer to the owner’s manual of the faulty equipment for troubleshooting help.
