Peavey Impulse 1015P operation manual Architectural and Engineering Specifications

Architectural and Engineering Specifications

The powered loudspeaker system shall have a frequency response from 56 Hz to 18 kHz. The peak SPL 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 a RX™22 compression driver tweeter. The nominal radiation pattern shall be 90˚ in the horizontal plane and 45˚ 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 1/4" TRS phone jack, and one male XLR, 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 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 of 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 W output into a 6 Ohm load. 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 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.

The enclosure shall be constructed of injection-molded polypropylene of 1/4" nominal thickness with a UL flame rating and internal reinforcing ribs. A handgrip shall be molded in to each side of the woofer and on the top rear edge.

A vinyl coated, perforated metal grille shall be provided for woofer protection. The cabinet shall incorporate four tall, sturdy rubber feet for floor standing use, and four mounting point inserts on the top and bottom for flying use.

The outside dimensions shall be 28.562" tall by 21.312" wide (11.5" wide in rear) by 17" deep, and the weight shall be 69 lbs. Power requirements shall be: 660 Watts, 120VAC, 60 Hz Domestic and 240 VAC, 50 Hz (European). The loudspeaker system shall be called a Peavey Impulse 1015P.
