The PRX900 Series Subwoofers is covered by this manual is 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. The PRX900 Series Subwoofers 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 Series Subwoofers 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

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. PRX915/918XLF is a self-contained PA system, which includes a mixing board, amplifiers, and speakers.
GETTING ACQUAINTED WITH PRX900 SERIES SUBWOOFER
The powered mixer section of the PRX915/918XLF Series Subwoofers houses the mixing board and power amplifier. Here,
line level sources like powered speakers and external mixers can be connected.

• 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 Pass Thru outputs
built into this JBL speaker.
• 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 subwoofer use cases. 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

• Flat – a flat tuned subwoofer preset
• 80hz – adjusts the subwoofer crossover point to 80hz
• 100hz – adjusts the subwoofer crossover point to 100hz
• 120hz – adjusts the subwoofer crossover point to 120hz
• Cardioid – adjusts the tuning, delay and polarity of the subwoofer to optimize its usage in cardioid mode.
For more on this, please see the Cardioid section of the guide.
• Speaker Delay
• 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 Pass
Thru XLR to subwoofer will need to be slightly delayed to make up for its closer position to the audience.
• Time Alignment Basics:
EASYNAV LCD
Intro to the EasyNav LCD

17
• 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.
• The PRX915/918XLF offer 20ms of speaker delay on it’s input stage.
• Polarity – This inverts the polarity of the subwoofer. OFF indicates the woofer is in standard polarity. ON means the polarity
of the subwoofer is reversed.
Settings
• BT Control Pairing” enables Bluetooth control pairing for up to 30 seconds with the JBL Pro Connect app. This turns off
when a pairing has been made, or after 30 seconds. When pairing with the app, please initiate control pairing first. Select
the speaker in the “Add Speakers” menu. The speaker will send a 4-digit pin back to the LCD. Confirm this using the MAIN/
MENU knob.
• “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.
• BLE Firmware Version - this is the version of BLE firmware loaded on your speaker.
• “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.

RIGGING DISCLAIMER
Only experienced professionals should attempt to suspend the speakers.
For permanent installation applications utilizing the M10 suspension points, JBL Professional recommends the use of three (3) M10 x 1.5
thread pitch forged shoulder steel eyebolts with an 18-20mm threaded shaft, along with fender washers, rated for overhead suspension.
Users unfamiliar with safe rigging practices should not attempt to suspend loudspeakers.
Raise the speakers as high as possible.
For best results try to get the high frequency horn at least 2 to 4 feet above the heads of the audience. If the speakers are too low, the
people in the back of the audience will not receive the best quality sound.
Place the speakers between the microphones and the audience.
Feedback occurs when the microphones pick up sound from the speakers and “feed” the sound back through the sound system. If space is
limited, point the speakers away from the microphones to reduce feedback.
Locate the speakers away from turntables.
Low-frequency feedback occurs when the output of the speaker is picked up by the tone arm of the turntable and is re-amplified. A heavy,
solid turntable base and shock mounting can also reduce this type of feedback in DJ applications.
Use more speakers in large or highly reverberant spaces.
Spreading speakers throughout these spaces will produce much better sound than trying to compensate with loudness level or equalization.
For very long distances, the use of another set of speakers with time delay is recommended.
Stand speakers upright for PA - Tilt the speakers back on the side for stage monitoring. Upright stance provides even coverage over a wide
area. EON speakers are also designed with two slanted positions for stage monitoring applications.

JBL Pro Connect
The JBL Pro Connect app is a Bluetooth Low Energy control application used to remotely control the features within the PRX900 Series
Subwoofer. The app is a free download on iOS and Android.
It is recommended that all users download the app and ensure their unit is operating on the latest firmware for the best
experience.
Firmware Update
If a firmware update fails on the PRX900 Series Subwoofers, please unplug the speaker, wait 1s before plugging back in and trying again.
