PRECAUTIONS The PRX800 Series speakers covered by this manual are not intended for use in 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.
SUSPENSION OF LOUDSPEAKER SYSTEMS Are You New to Rigging? If you are new to rigging, you should do the following: • Read and study JBL Technical Note Volume 1, Number 14: Basic Principles for Suspending Loudspeaker Systems (available at http://www.jblpro.com/catalog/support/getfile.aspx?docid=296&doctype=3). • Know the rules for safe rigging.

THE PRX800 SERIES POWER AMPLIFIER AC Power Requirements Standard PRX800 Series speaker systems are equipped with a multi-channel Class-D power amplifier and loudspeaker-specific DSP electronics and require appropriate AC power. Before plugging a PRX800 speaker into an outlet, ensure that it is able to provide the appropriate AC power as required by the speaker. A robust AC supply is necessary for maximum performance.
INTRODUCTION TO THE PRX800 SERIES PRX812 PRX815 PRX815XLF PRX818XLF PRX825 PRX835 Thank you for choosing the JBL PRX800 Series self-powered PA loudspeakers. The PRX800 Series represent an evolutionary step in the efficient use of amplifier power, rugged durability and enhanced versatility in a selfpowered loudspeaker with WI-FI application configuration and control.
Powered Speaker Systems A Closed System Architecture… There is much confusion these days in the world of powered speakers, especially when it comes to defining “performance”. What constitutes “exceptional performance”? Is it wattage ratings, driver dimensions, cabinet dimensions, sound pressure levels, tone? It can get very confusing when you’re confronted with a barrage of specifications from manufacturers all claiming to have the “best performance”.

Features 1. POLARITY LED – This light indicates whether the polarity is set to Normal or Inverse Polarity. When the light is ON, speaker polarity is inverted. 2. POLARITY Button – This push button allows you to choose between 0° (Normal) or 180° (Inverse Polarity). The correct polarity setting will produce the best blend between the subwoofer and the full-range speaker and the strongest perceived bass response at the listening position. If the bass response seems weak, try inverting the polarity.
WI-FI SETUP To connect to the PRX800 speakers via WI-FI, perform the following: 1. Download the app from www.jblpro.com then install it. 2. Power on all PRX800 speakers in your setup. 3. The application will display a welcome screen — select “SET UP A NEW SYSTEM”. 4. Enter the name of the band and the name of the venue. 5. Select NEXT. 6. Go to the back of each speaker and set it to Access Point mode by pressing and holding the CONNECT button for 2 seconds — the CONNECT LED will begin flashing slowly. 7.
FACTORY RESETS The following Factory Resets will reset settings back to their factory default state. This can be useful when you wish to reconfigure a speaker from scratch. WARNING: Performing the following reset procedures will result in the loss of settings and cannot be undone! Factory Hard Reset The Factory Hard Reset resets all DSP and network settings back to their factory default state. To perform the Factory Hard Reset: 1. Turn the speaker power off. 2.
TROUBLESHOOTING Symptom Likely Cause Speaker not connected to active AC power. No sound. No sound, speaker is connected to working AC power but won’t come on. No sound. Speaker comes on. No sound with microphone connected directly to the MIC input. Verify that speaker is connected and that circuit is on. Switch on power and verify that illuminated logo is on. • Re-seat the power cable at both ends. • Substitute a known-good power cable. Blown fuse. Signal source (mixer, instrument, etc.
Symptom Likely Cause What to do Improper A/C grounding, ground loops. • “Telescope” the audio ground by using an XLR/F to XLR/M adapter on one end. • Re-route audio cable away from AC power and lighting cables. Excessively long unbalanced cable run. • Use the balanced outputs (if available) of your mixer or source equipment to drive your PRX800 speakers. • Use a “DI” (direct injection) box to convert your unbalanced equipment output to a balanced output. Improper system gain structure.
