PR 15D Manual (pdf)

The Peavey PR 15D is a powered, bi-amplified, two-way speaker system engineered to provide very high levels of performance in a compact powered loudspeaker. The PR 15D 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 15" 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 ZLR and ¼" TRS phone jack. It is switchable between mic-level and line-level sensitivity. Two ¼" 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 the patented 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.

Architectural and Engineering Specifications

The powered loudspeaker system shall have a frequency response from 47 Hz to 20 kHz. The peak SPL with inaudible distortion shall reach 120 dB with music as a source, when measured at a distance of one meter and driven to full output capacity. The system shall utilize a 15" heavy duty woofer and an RX14 compression driver tweeter. The nominal radiation pattern shall be 90° in the horizontal plane, and 40° in the vertical plane.

The powered, bi-amplified loudspeaker system shall have a group of medium impedance input connectors consisting of one combo female XLR and ¼" TRS phone jack, and two ¼" phone jacks, on the rear panel. A volume control will be located near each input jack. The combo female XLR and ¼" TRS phone jack will have a gain adjust pad that provides for switching between line-level input signals, and mic-level input signals.

The system power amplifiers shall have an unfiltered frequency response of 10 Hz to 30 kHz which deviates no more than +0, -1 dB up to rated power, a damping factor greater than 100 @ 1 kHz into 8 ohms, hum and noise better than 90 dB below rated power, and THD and IMD of less than 0.1%. The woofer amplifier shall be capable of 150 W into a 8 ohm nominal load, and the tweeter amplifier shall be capable of 50 W output into a 8 ohm load, and both shall incorporate independent DDT™ compression.

The input signal shall be electronically divided into high frequencies and low frequencies by a staggered-pole third order slope line-level crossover at 2 kHz. The low frequencies shall be processed to provide bass boost, subsonic filtering and overall response shaping, and the high frequencies shall be equalized for constant directivity horn EQ- and response-shaping.

The enclosure shall be constructed of injection-molded polypropylene of ¼" nominal thickness with a UL flame rating, and reinforcing ribs internally. A handgrip shall be molded-in on the top rear edge, and one on each side of the woofer.

A powder-coated metal grille shall be provided for woofer protection. The cabinet shall incorporate a pole mount for speaker stand use, four tall sturdy rubber feet for floor standing use, and four mounting point inserts on the top and bottom each for flying use.

The outside dimensions shall be: 28.56" tall by x 21.31" wide (11.50" in rear) by x 17.00" deep, and the weight shall be 37 lbs. Power requirements shall be: 100 Watts nominal, 100 & 200 VAC, 50/60 Hz Domestic and 220-240 VAC, 50/60 Hz (Export). The loudspeaker system shall be called a Peavey PR 15D.
