PRODUCT FEATURES
All-New Acoustic Designs
From cone to cabinet, the PRX912 has been built from the ground up to leverage
the latest JBL acoustic innovations. A patented JBL 2408H-2 1.5” compression
driver with poly-annular diaphragm and neodymium magnet provides clear,
detailed high-frequency response even at maximum volume. High-quality NTC
thermistors protect transducers by reducing power sent to transducers when
approaching thermal limit. Innovative new horns with updated JBL Image Control
Waveguides provide optimum beamwidth and directivity. A next-generation woofer
with ferrite magnet delivers smooth, natural bass and mids.
Power That Performs for You
PRX900 systems effortlessly support large performance spaces with high power
and performance needs. Driven by a highly efficient2,000W (peak) Class D power
amp, PRX912 provides acoustic clarityand definition with minimal power
compression, even at maximum volume. A bridged woofer amp keeps current spikes
out of the ground and lowers crosstalk harmonics to the compression driver,
and a power factor correction (PFC) power supply stabilizes voltageload sent
to the amplifier. High-quality, high-linearity inductors deliver high power
efficiency and low total harmonic distortion, and low-noise, low-distortion
input gain staging optimizes range and headroom for a diverse gain
requirements. A high-quality DAC and ADC provide near-lossless audio
conversion. And with a full-bandwidth CMRR (Common Mode Rejection Ratio)
greater than 55 dB and THD (total harmonic distortion) rating of <32 dB,
system noise is virtually nonexistent.
Dial In Your Sound With Class-Leading DSP
PRX912 is fully loaded with comprehensive DSP, all accessible via the JBL Pro
Connect app and onboard full-color LCD. Processing includes 12-band parametric
EQ and optimized system presets. Onboard dbx DriveRack technology features
live and fixed Automatic Feedback Suppression, soft system limiters and 180ms
of speaker delay in 100-microsecond intervals for precise time-aligned
systems.
Versatile and Scalable
Combine PRX900 Series loudspeakers and subwoofers in a range of configurations
to meet the needs of both mobile scenarios and fixed installs. PRX912 features
dual 36mm pole sockets and six M10 suspension points. A built-in gyrosensor
automatically optimizes tuning depending on monitor or mains placement.
Part of the Pro Connect Ecosystem
The JBL Pro Connect app offers BLE functionality for system control of up to
10 speakers and line integration with JBL EON ONE MK2, PRX ONE and EON700
loudspeakers. The app provides full access to to the PRX900 Series’ DSP
package, and users can easily mute channels and speakers with the touch of a
button and can change speaker names and flash all unit LEDs for ease of
speaker identification. App-exclusive features include speaker snapshots and
groupings.
Rugged and Road-Worthy
PRX912 components are housed in a strong, lightweight enclosure that maximizes
both acoustic performance and durability. Its cabinet is constructed from a
polypropylene/talcum blend that’s optimized for rigidity, with a computer-
modeled internal ribbing design for maximum structural integrity and minimal
cabinet noise.
In It for the Long Haul
Like every JBL product, the PRX912 undergoes an industry-leading 100-hour
stress test of all components to ensure systems perform beyond expectations in
real-world scenarios. It’s so reliable that it’s backed with an unprecedented
seven-year warranty.
