Peavey specifications Specifications Quadra 12P, Electroacoustic crossover frequency 1,800 Hz

Specifications Quadra 12P

Electroacoustic crossover frequency: 1,800 Hz

Crossover type:

Internal, electronic two-way crossover with CD horn EQ, level matching, active bass boost and subsonic filtering. The horn is spatially aligned with the woofer, eliminating the need for phase alignment or signal time delay.

Crossover slopes:

18 dB/octave (third order) low pass and 18 dB/octave (third order) high pass, both with staggered poles and driver EQ.

Electronic input impedance (nominal):

10 k Ohms unbalanced, 20 k Ohms balanced.

Input connections:

One combo female XLR and 1/4" phone jack, and one male XLR providing balanced operation in parallel. Also has a 1/4" phone jack-based Loop Thru that allows other Quadra 12P units to be linked to a single unit for signal source and level control.

Contour switch: Reduces mid-range by approximately 4 dB, from 200 Hz to 3 kHz.

Enclosure materials and finish: Injection-molded, high-impact 1/4" thick polypropylene with internal ribbing and bracing, textured finish and a UL flame rating. Molded material is black.

Mounting:

Peavey Versamount™ 70 for flying (top or bottom of cabinet), Peavey array brackets and four rubber feet for floor use.

Dimensions:

Front: 23.65" H x 17.75" W x 14.00" D 601 mm x 451 mm x 356 mm Rear: 22.25" H x 10.00" W x 14.00" D 565 mm x 254 mm x 356 mm

Optional accessories:

Floor monitor leg kit

Net weight: 56 lbs.

Shipping weight: 62 lbs.

Additional remarks:

Also available as a passively crossed-over unit, Quadra 12, 8 Ohms.

Description

The Quadra 12P is a powered, bi- amplified, two-way speaker system engineered to provide the highest levels of performance available 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 for a cosmetically elegant yet durable powered speaker system.

This two-way powered system is comprised of an 800 Watt dynamic peak power amplifier driving a 12" BWX Black Widow woofer (1208-4) with a Kevlar™ impregnated cone, with surround and dust cap specially treated for excellent environmental stability. A 200 Watt peak dynamic power amplifier drives the RX22 compression driver and features a 2" titanium diaphragm with Radialinear Planar Phase Correction in the phase plug (US Patent #6064745). A Quadratic Throat Geometry constant directivity horn (US Patent #6059069) with a coverage pattern of 90˚ by 45˚ is molded integrally into the enclosure.

The Quadra 12P houses one combo female XLR, a 1/4" RTS phone jack and one male XLR in its preamp, all connected in parallel. A separate, switchable female XLR microphone input is also provided. The power amplifiers are low distortion units providing 400 W RMS into the nominal 4 Ohm load of the woofer and 100 W RMS into the nominal 6 Ohm load of the tweeter, both selected for their reliability and superb musical performance capability. Both amplifiers feature our patented SPS compression, which virtually eliminates audible power amplifier clipping.
