The 12" JBL PRX712 1500W Two-Way Multipurpose Self-Powered Speaker is designed to be a stage monitor or front of house PA for live sound reinforcement applications, such as concerts, schools, and houses of worship, among others. The speaker is built from poplar plywood with an obsidian DuraFlex finish using tongue and groove joinery for stronger bracing and less box vibration.
It utilizes a 12" low-distortion, low-frequency woofer, a wave-guided 1.5" diameter neodymium compression driver, and a class-D amplifier to achieve a maximum SPL of 135 dB and a frequency response of 44.8 to 19,600 Hz.
For easy transport and setup, the speaker includes an injection molded handle, 16-guage steel dent-resistant cloth-backed grills, integrated M10 suspension points for hanging, and integrated 36mm pole mount sockets for use with a speaker poles.
The back panel of the speaker features two combination 3-pin XLR and 1/4" balanced inputs for microphone and line signals with a selector switch as well as a pair of unbalanced RCA inputs. Two gain control knobs allow you to adjust the input signal on channels 1 and 2, and a 3-pin XLR male thru connection with thru selector switch enables passing audio to another powered speaker or amplifier.
The device includes an EQ boost button for widening the speaker's frequency response and a button for turning on and off the power/standby LED on the front of the device.
The speaker's crossover, dynamic limiting, component optimization, and selectable EQ boost is handled by a dbx type IV circuit. The unit can be used by itself or connected with other PA speakers and subwoofers to build larger systems with increased crowd coverage and low frequency response.

is a compact and versatile speaker in the PRX700 Series. It has been
designed to deliver maximum performance for its weight and size as both a
stage monitor and a front of house main PA. Two user selectable EQ
settings are provided to optimize the system for either application.
With a dual socket pole mount the PRX712 is a perfect match with a
PRX718XLF subwoofer, offering a high performance self-powered sub/sat
system.
- The PRX712 is comprised of a 12"
Differential Drive® woofer, a 2408H-1, 37.5 mm (1.5 in) annular polymer
diaphragm, neodymium compression driver mounted to a 90° by 50° horn,
all driven by 1500 watt Class-D digital power amplifier. Sophisticated
DSP is at the core of a fully featured input section, providing user
selectable system EQ, protection, input sensitivity selection,
cross-over functionality, dynamic limiting and discrete component
optimization.
- All PRX700 cabinets are built
from a combination of 25mm (on the top and bottom for added rigidity)
and 18mm, strong, light-weight poplar plywood made structurally sound
with tongue and groove joints. All PRX700 Series cabinets are protected
by JBL’s tour proven DuraFlex™ finish. Grilles are made from
dent-resistant 16 gauge steel and handles are made from light-weight
glass-filled nylon for added strength and durability. All M10 suspension
points are constructed from 14 gauge steel and have been tested with a
yield-strength of
1000 lbs. each. - The
amplifier input panel offers XLR or Ľ inch jack compatibility and a
sensitivity switch provides extra flexibility, making it possible to
connect literally any sound source without using a mixer. Signal present
and limiter lights indicate the system status and assist in setting the
optimum level via the level control knob.

Do
I need a return authorization to return my JBL product to the factory
for repairs?
Yes. A service authorization is required and will be
issued for you
to
include on the packing slip and the on the outside of the box.
What happens once JBL receives
the product for repair?
The failure mode and cause of failure is determined by our Senior
Technician. When a copy of the proof of purchase is enclosed in
the package, all failures covered under the warranty are repaired
and the product is returned without any charge to the customer.

not covered under the warranty will be charged for the repairs
and shipping. JBL Professional Customer Service will fax or mail
a JBL Professional Estimate of Repairs and will not proceed with
the repairs until customer's reply is secured. Payment terms for
repairs are payment in advance via cashiers check, money order,
Visa, MasterCard or American Express.
How
is the warranty coverage verified?
Your JBL Warranty protects the original owner and all subsequent
owners (see below) so long as:
- Your JBL
product was purchased in the Continental United States, Hawaii
or Alaska. This Warranty does not apply to JBL products purchased
elsewhere except for purchases by military outlets. Other purchasers
should contact the local JBL distributor for warranty information.
- The original
dated bill of sale or proof of purchase is presented whenever
warranty service is required. In lieu of the original bill of
sale, JBL will accept a duplicate bill of sale issued by the
selling dealer or a clear photocopy of the original bill of
sale.
Is
the JBL warranty transferable?
Yes. The JBL Warranty is transferable so long as the original
dated bill of sale is presented whenever warranty service is required.
Where the product to be repaired is no longer the property of
the original owner and the original or a copy of the bill of sale
cannot be provided, JBL will accept a notarized statement by the
original purchaser stating the name of the selling dealer, date
of original purchase, invoice or sales ticket number, model and
serial number of the product including the date of transfer from
the original purchaser to the subsequent owner of the product.
The subsequent owner(s) of the product will pick up the balance
of the warranty period based on the original dated bill of sale.
What is the warranty on repairs
and replacement parts?
Products serviced by an authorized JBL Professional Service Agency
are warranted against defects in workmanship and materials for
a period of 90 days, or the remainder of the original warranty
period, whichever is greater. The Service Agency must use JBL
factory parts for this warranty to be in effect.
Why
can't end users purchase cone kits?
Because replacing a driver's cone, suspension and voice coil requires
special test equipment, tools and training.
Can I use a different crossover
in my speaker cabinet?
No. Because each passive crossover is designed to accommodate
specific loudspeaker components, changing to a different passive
crossover will change the sound and response of the loudspeaker
system.
Will a different driver work
in my cabinet?
As certain speakers become obsolete, it is necessary to replace
them with alternative product. For the best possible replacement,
contact your local JBL Professional Warranty Station or Technical
Support at JBL.
