8 Changing Voltage Y our 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.
9 Operating T emperature 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.
10 Thank you for choosing the JBL PRX500 series self-powered P A 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.

16 Features 1 - EQ BOOST / FLA T : When set in the “FLA T” position, frequency response is linear and unaltered.When “Boost” is selected, internal equalization is applied to enhance low frequency and high frequency response.
17 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.
18 Features 1 - XOVER IN / OUT : Pressing this button engages a high-pass filter at 1 10 Hz. This 4th order active filter allows a smooth transition between the subwoofer and a full range speaker connected to the output connector .
19 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).
20 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.
21 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.
22 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 .
23 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 .
24 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.
