User manual PEAVEY QUADRA 12P DATASHEET

[. . . ] Loop Thru input: High-Z Infrasonic filter protection: 36 dB/octave roll-off For both power amps: Nominal amplifier frequency response: +0, -1 dB from 10 Hz to 30 kHz Hum and noise: Greater than 90 dB below rated power. SPSTM compression dynamic range: Greater than 26 dB THD and IM: Typically less than 0. 1 % Woofer power amp: Damping Factor: Greater than 100 @ 1000 Hz, 4 Ohms. [. . . ] 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. Mounting: Peavey VersamountTM 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 Specifications Quadra 12P switchable microphone input (female XLR) and a Loop Out/Loop In is provided. A volume control is located next to the input jack group. The system power amplifiers have an unfiltered frequency response of 10 Hz to 30 kHz, which deviates no more than +0, -1dB 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 of less than 0. 1%. The woofer amplifier is capable of handling 400 Watts into a 4 Ohm nominal load, and the tweeter amplifier is capable of 100 Watts output into a 6 Ohm load. Both incorporate independent SPS compression. The input signal is 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 are processed to provide bass boost, subsonic filtering and overall response shaping, and the high frequencies are equalized for constant directivity horn EQ and response shaping. [. . . ] The system utilizes a 12" BWX Black Widow woofer and an RX22 compression driver tweeter. The nominal radiation pattern is 90° in the horizontal plane and 45° in the vertical plane. [. . . ]
