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. In the event that you do need to change the v[...]

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. A Condition under which this [...]

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. “FLA T” will provide greater accuracy of reproduced music, higher speech intelligibility and maximum overall leve[...]

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. 3 - LEVEL: Sound level adjustment. With the input in the “MIC” position the level can be adjus[...]

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 . 2 - POLARITY INVERT : Allows you to set the polarity of the subwoofer to either 0° (no change) or 180° (inverse pola[...]

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). 6 - POWER SWITCH: T urns the power on. Power “on” status is indicated with the ill[...]

20 PRX500 series systems have been designed to allow the connection of a variety of sources.

Low levels output from consumer products like MP3 and CD players, can also be accommodated. There are t[...]

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.

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 . From the master outputs of [...]

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. The mor[...]
