Architect's & Engineer's Specifications The powered loudspeaker system shall have a frequency response from 63 Hz to 20 kHz. The peak SPL with inaudible distortion shall reach 127 dB with music as a source, when measured at a distance of 1M and driven to full output capacity. The system shall utilize a Peavey Pro 12 12 inch heavy-duty woofer and a Peavey RX 14 1.4 inch titanium diaphragm dynamic compression driver. The nominal radiation pattern shall be 100 degree in the horizontal plane, and 50 degree in the vertical plane. Axis of the vertical main polar lobe is angled down 10 degrees, resulting in the angular pattern with respect to straight ahead being +15, -35 degrees The powered, bi-amplified loudspeaker system shall have three input channels consisting of a medium impedance input connector consisting of one combo female XLR and 1/4 inch TRS phone jack for channel 1 and channel 2 on the rear panel. Channel three shall provide Bluetooth signal source input control, as well as doubling as an AUX in for a 1/8 inch phone jack. There shall be a output connector consisting of a male XLR jack. The system power amplifiers shall have an unfiltered frequency response of 20 Hz to 20 kHz which deviates no more than +0, -3 dB up to rated power, hum and noise better than 90 dB below rated power, and THD and IMD of less than 0.5%. The woofer amplifier shall be capable of 375 Watts sine wave power output into a 4 Ohms nominal load, and the tweeter amplifier shall be capable of 50 Watts sine wave power output into a 8 Ohms nominal load, before compression and limiting engage, and both shall incorporate independent DSP controlled signal compression. The input signal shall be electronically divided into high frequencies and low frequencies by a fourth 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 response-shaping. The enclosure shall be constructed of injection-molded plastic with a UL flame rating, and reinforcing ribs internally. A handgrip shall be incorporated on each side near the woofer and towards the front, and on the right side of the cabinet. A separate powder-coated metal grille shall be provided for horn and woofer protection. The cabinet shall incorporate a pole mount for speaker stand use, four tall sturdy rubber feet for floor standing use, and a group of four mounting point inserts on the top and bottom each, and on the right side, for flying use. The outside dimensions shall be: 24.50 inches (622 mm) tall x 16.10 inches (409 mm) wide x 15 inches (381 mm) deep, and the weight shall be 42 lbs (19.1 kg). Power requirements shall be: 120 Watts nominal, 100-120 VAC, 50/60 Hz Domestic and 220-240 VAC, 50/60 Hz (Export). The powered bi-amped loudspeaker system shall be the Peavey PVXp 12 Bluetooth or approved equivalent.
