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. The PRX900 system can generate considerable energ y. 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.
HEARING DAMAGE, PROLONGED EXPOSURE TO EXCESSIVE SPL
The PRX900 system is 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 85 dB.
CARE & CLEANING
PRX900 systems may be cleaned with a dry cloth. Do not allow moisture into any of the openings in the system. Ensure that the system is unplugged from the AC outlet before cleaning.

OVERVIEW

P.A. BASICS
A mixing board is actually a very simple device that takes the audio input signals (from the input channels) and “mixes” them to the outputs. The mixing board controls will typically enable the user to blend the input channel signal levels, affect their tone, and adjust each channel’s reverb level. The signal is then fed from the mixing board to the amplifiers and onto the speakers. The PRX900 is a self-contained PA system, which includes a mixing board, amplifiers, and speakers.
GETTING ACQUAINTED WITH PRX900
The powered mixer section of the PRX900 system houses the mixing board and power amplifier. Here, all of the microphones, musical instruments, and external sound sources (such as MP3 players and CD players) can be connected.

Intro to the EasyNav LCD
Main Menu

  • Pressing the Main/Menu rotary at any time will take you to the PRX900’s main menu. Here, users can access the main menu functions of the PRX900.
  • Gain adds preamp gain to the system to support microphone usage. PRX900’s fader runs standard in LINE LEVEL, but accessing the GAIN menu can allow users to plug a microphone in directly.
    • Press The Channel knob to access the Gain menu for that channel.
    • Once in the gain menu, turn the main knob to adjust the gain to your desired levels.
  • dbx DriveRack Output – DriveRack is a line of hardware products produced by Harman’s dbx brand. These rack mount signal processors provide detailed control for final processing and crossovers before feeding the mix to one or more speakers. This DriveRack functionality embedded into PRX900 is designed to optimize the combination of speaker and Mix Output built into this JBL speaker.
    • AFS by dbx, or automatic feedback suppression, is a combination of processing that can enable the user to add up to 3 dB more total gain to their output before getting audio feedback back in through the mix inputs. AFS does this using a combination of auto sensing and very tight width parametric EQs before the output master EQ.
      • Stage setup best practices are always recommended for best results to avoid feedback, in combination with the AFS processing system. Microphones have less chance of contributing feedback if they follow the following position standards on stage:
        • Microphones should be behind the front plane of the speakers.
        • Microphones should be least two meters to the left or right of the speakers.
  • “AFS by dbx” On/Off selection toggles the AFS processor on or off.
    • “Reset Filters” will reset all filters, prompting the filters to reset and start over in their discovery of potential feedback frequency risks.
    • The Output EQ is a package of filter adjustments on the main mix before the audio feeds to the amp and speaker. It includes a collection of easy to select preset curves for common speech and music styles. Each preset can also be loaded into the Custom preset for detailed user adjustable of output parametric EQ’s. The user has adjustments for individual band level, frequency, and width (“Q”).
      • “Output EQ” On/Off enables or bypasses the current settings in the output EQ processor.
      • “Presets” enables rotation of the Main/Menu knob to view and select from the Output EQ presets.
      • Scroll the menu to “Presets” and press the MAIN/MENU knob.
    • Rotate the MAIN/MENU knob to view the available presets.
    • Click the MAIN/MENU knob to load the currently listed preset.
      • Users can load the Custom preset, then double click the MAIN/MENU knob to open the Master EQ editing page. Inside this graph display page you may rotate the MAIN/MENU knob to a specific parametric EQ number and click the MAIN/MENU knob again to select to edit the gain (plus or minus in dB), filter frequency, or “Q” (i.e. adjust the filter width.)
  • Users can load any preset as a starting point, then scroll down and adjust any setting to load the current curve as the Custom preset for further editing. A confirmation dialog will appear, warning the user that doing this will remove the current Custom preset settings and load it with the currently viewed settings.
  • The Limiter provides a “brick wall” limiter on the master mix, after the Master EQ in the signal chain. Limiters reduce the loudest parts of the mix dynamic range. Limiters can be used either for protection when playing very loud source material, or to creatively sculpt down the loudest dynamics of the master mix. Carefully turn up the Makeup Gain to compensate for low threshold limiter results.
    • “Reset” is an action command to reset the Output Limiter to the factory default setting.
    • “Presets” are available to recall limiter settings for common creative situations or trouble shooting.
    • If the user selects any of the lower three settings to edit, the preset automatically loads the lower three settings to the Limiter “Custom” preset for further user editing.
    • “Threshold” enables the user to set the threshold level, limiting the maximum mix level to amp and speakers. All dynamic range above that level will be limited down to the maximum Threshold setting.
    • “OverEasy” an Enabling “OverEasy” smooths the transition before the signal reaches the Threshold level to provide a smooth limiting audio result. “OverEasy” is often selected on rock ballads or speaking panels. Turning off OverEasy is often desired on harder rock or DJ style of music program.
    • “Makeup Gain” can be used to raise a limited mix to pre-limiter levels. Warning: Using limiter “Makeup Gain” on already loud mixes may exceed desired mix gain levels. This setting is best used only by skilled audio professionals. Small movements are best when adjusting limiters.
  • Bass Boost – The Bass Boost functionality adds 3db of bass at 80hz to the system. · Bass Boost On/Off enables or disables bass boost functionality.
  • Mix Out XLR output can be set to assist in feeding the mix to additional speakers. This section includes presets and settings based on the type of speaker the Mix Out will be feeding and how it is positioned in comparison to this speaker and the audience.
    • “Mix Out” On/Off” enables or disables the Mix Out XLR output feed.
    • “Presets” enables selection of three types of speakers combinations using the Mix Out XLR output:
      • “Full Range” is designed for feeding another full range speaker.
      • “Sub” preset automatically configures settings for isolating low frequencies and feeding them to Mix Out XLR out for a subwoofer speaker. Selecting “Sub” automatically sets the internal amp/speaker feed to HPF (“high pass filter”) only signal at above 80Hz and the Mix Out XLR output to only pass the mix signal below 80Hz.
      • “Custom” allows the user to set the settings manually.
    • “HPF on this Speaker” can be used to remove signal below a selected frequency to the built-in amp/speaker.
    • “LFP on Mix Out”can be used to set the low pass filter on the Mix Out XLR output feed.
  •  Time Align
    • Signal delays are used when multiple speakers are in use but speakers are at different distances from the audience.
    • Examples:
      • A subwoofer in front of the stage, while this full range speaker in on the stage. In this configuration, the Mix Out XLR to subwoofer will need to be slightly delayed to make up for its closer position to the audience.
      • The Mix Out XLR out is feeding an additional full range speaker placed half way back in the audience, to give additional listening distance. In this case, delay the back fill speaker in the audience to compensate correct time alignment.
  • Time Alignment Basics:
    • To compensate for different distances’, determine the speaker farthest from the audience and delay other speakers with the same signal to “time align” with the speaker farthest away from the audience.
    • Sound travels through air at average humidity and room temperature at about 1.1 feet per ms. Measure the difference in distance of each speaker feeding the audience. Feed the speaker farthest from the audience with no time alignment delay. Set delays for the other closer speakers based on their distance ahead of the farthest back speaker. Measure the distance difference and enter 1 ms per 1.1 feet that each speaker is ahead of the farthest back speaker in your configuration. Time alignment is not perfect as not all audience positions measure the same speaker distance differences.
    • “Delay Mix Out” places audio signal delay on the Mix Out feature of the PRX900 Series. You can place up to 20ms of signal delay adjustable in 100 microsecond intervals.
    • “Delay This Speaker” adds up to 180ms of signal delay to the power output section of the speaker, adjustable in 100 microsecond intervals..

Settings

  • “BT Control Pairing” enables Bluetooth control pairing for up to 30 seconds with the JBL Pro Control app. This turns off when a pairing has been made, or after 30 seconds.
  • The PRX900 loudspeaker will confirm a secure pin with the app. Please ensure you confirm this to secure BLE control pairing.
  • “LCD Contrast” allows the user to adjust the LCD contrast between 0 and 100%.
  • “Firmware Version” shows the current firmware version loaded onto the speaker.
  • “Factory Reset” resets all settings in the speaker to factory default, including Bluetooth communication pairing.
  • “System lock” locks out all hardware operation from the speaker.
    • To initiate system lock, press and hold the POWER button and the BACK button until all LEDs flash and a LOCK icon appears in the top left corner of the LCD. OR Navigate to the System Lock field in the settings menu, and select CONFIRM.
    • To disable system lock, press and Hold the POWER button and the BACK button until all the LEDs flash the lock icon disappears from the top left corner. OR Remove AC power and reboot the system.

Other purchasers should contact the local JBL distributor for warranty information.); and B.) The original dated bill of sale is presented whenever warranty service is required.
What Does The JBL Warranty Cover?
Except as specified below, your JBL Warranty covers all defects in material and workmanship. The following are not covered: Damage caused by accident, misuse, abuse, product modification or neglect; damage occurring during shipment; damage resulting from failure to follow instructions contained in your Instruction Manual; damage resulting from the performance of repairs by someone not authorized by JBL; claims based upon any misrepresentations by the seller; any JBL product on which the serial number has been defaced, modified or removed.
