PR 12D
®
Thank you for purchasing the class D powered PR 12D. The PR 12D features a bi-amped power section that provides 150 watts power
®
for the woofer and 50 watts power for the compression driver tweeter, both with DDT compression. Featuring a 12" heavy duty
™
woofer and the RX 14 compression driver, the PR 12D provides an XLR and 1/4"phone combo jack, with mic/line switchable level,
™
balanced input with volume control.

Description
The Peavey PR 12D is a powered, bi-amplified, two-way speaker system engineered to provide very high levels of performance in a
compact powered loudspeaker. The PR 12D is capable of up to 120 dB peak SPL. The enclosure utilizes tough polypropylene in an
injection-molded plastic trapezoidal form, with a coated steel grille to offer an attractive yet-durable powered speaker system.
This two-way powered system is comprised of a 150 W class D power amplifier driving a 12" heavy duty woofer. The RX ™ 14
compression driver is driven by a 50 W class D power amplifier and features a 1.4" titanium diaphragm coupled to an extremely smooth
and well-controlled constant directivity horn (with a coverage pattern of 90˚ by 40˚) that is molded integrally into the enclosure.
A balanced input to the preamp/EQ electronics consists of one combo female XLR and 1/4" TRS phone jack. It is switchable between
mic-level and line-level sensitivity. Two 1/4" phone jacks are provided for link-out / direct-in capability. The link-out is post- level and
pre-crossover. While the direct-in is a direct pre-crossover input.
A woofer servo senses back-EMF from the woofer voice coil that is not a result of the drive signal, and subtracts the error so that the
woofer cone follows the drive waveform precisely.
Constant Loudness (Fletcher-Munson) circuit for accenuating bass and treble at low listening volume levels.
The power amplifiers providing the bi-amplification are low-distortion units providing 150 W continuous RMS into the nominal 8 ohm
load of the woofer, and a 50 W continuous RMS into the nominal 8 ohm load of the tweeter. They were selected for their reliability and
superb musical performance capability. Both amplifiers feature DDT ™ compression, which virtually eliminates audible power amplifier
clipping.

A molded-in handle provides ease of transport, while multiple mounting points (top and bottom) for the Peavey Versamount allow
maximum utility.
