After the first few months of use and periodically thereafter, check the hardware of the Quadra
®
15P
for tightness, including the rear panel screws and the screws that hold the baffle and rear cabinet
together. The unit is subject to a great deal of vibration, and this could cause them to loosen with
use.
The Peavey Architectural Acoustics
®
Quadra 15P is a powered, bi-amplified two-way speaker system
engineered to provide the highest levels of performance possible in a compact, powered
loudspeaker. Capable of over 130 dB peak SPLs, this system can pump out a huge amount of sound.
The enclosure utilizes high-impact polypropylene in an injection-molded plastic trapezoidal form,
with a coated, perforated metal grille to offer an aesthetically pleasing-yet-durable powered speaker
system.
This two-way powered system is comprised of an 800 Watt dynamic peak power amplifier driving a
15" BWX Black Widow
®
woofer (1508-4 SPS) with a Kevlar
™
impregnated cone, surround and dust
cap specially treated for excellent weather resistance. The RX
™
22 compression driver is driven by a
200 Watt peak dynamic power amplifier and features a 2" titanium diaphragm, covered by U.S.
Patent #6064745 (UK GB 2 329 789) for the Radialinear Planar Phase Correction System used in its
phase plug. It is coupled to a patented Quadratic Throat Geometry constant directivity horn (U.S.
Patent #6059069) with a coverage pattern of 90˚ x 45˚, molded integrally into the enclosure.
Balanced inputs provided to the preamp/EQ electronics are one combo female XLR and 1/4" TRS
phone jack, and one male XLR, all connected in parallel. A separate, switchable microphone input
(female XLR) is also provided. The power amplifiers providing the bi-amplification are low distortion
units pushing 400 Watts RMS into the nominal 4 Ohm load of the woofer and 100 Watts RMS into
the nominal 6 Ohm load of the tweeter. They were selected for their reliability and superb musical
performance capability. Both amplifiers feature our patented SPS
™
compression, which virtually
eliminates audible power amplifier clipping.
Multiple molded-in handles make transport easy, while multiple mounting points (top, bottom and
rear) for the Peavey Versamount
™
70 and a molded-in stand adapter provide maximum utility.
The Quadra 15P powered loudspeaker system shall have a frequency response from 56 Hz to 18 kHz.
The peak SPLs with inaudible distortion shall reach 130 dB with music as a source, when measured
at a distance of 1 meter and driven to full output capacity. The system shall utilize a 15" BWX Black
Widow
®
woofer and an RX
™
22 compression driver tweeter. The nominal radiation pattern shall be 90˚
in the horizontal plane and 45˚ in the vertical plane.
This powered, bi-amplified loudspeaker system shall have a group of medium impedance input
connectors consisting of one combo female XLR and 1/4" TRS phone jack and one male XLR, all on
the rear panel and connected in parallel. Additionally, a separate, switchable microphone input
(female XLR) shall be provided. A Loop Out and a Loop In jack shall be provided. A Volume control
will be located next to the input jack group.
The system’s 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
4 Ohms; hum and noise better than 90 dB below rated power; and THD and IMD less than 0.1%.
The woofer amplifier shall be capable of 400 Watts into a 4 Ohm nominal load and the tweeter
amplifier shall be capable of 100 Watts output into a 6 Ohm load, and both shall incorporate
independent SPS
™
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 1.8 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.
