ATC (Acoustic Transducer Company) Loudspeakers is introducing the ATC PA65, a new compact, three-way active PA speaker system for flown, live sound installation, at AES NYC 2005. The ATC PA65 live sound speaker system was initially developed from the company's SCM150ASL active studio monitors.
The three-way active PA65 system comprises an ATC Super Linear 15-inch bass driver, a three-inch Soft Dome mid-range driver and a 1.25-inch fabric dome tweeter. ATC three-channel Class A/B amplifiers deliver 200 watts to the low-frequency driver, 100 watts to the mid-range and 50 watts to the tweeter. All amplifier channels feature active momentary gain reduction.
Each three-way active enclosure is capable of generating a maximum SPL of 116dB. Each cabinet offers 80 degrees of horizontal, coherent dispersion with 10 degrees in the vertical plane. Crossover frequencies are set at 380Hz and 3.5kHz. The PA65s come with flying hardware.
ATC hand builds their loudspeakers. All drive units are powered by individual amplifiers optimized for the driver's bandwidth, delivering balanced maximum sound pressure levels, substantial transient headroom with improved driver protection and precision control over speaker diaphragm travel. Even order filtered active crossovers are individually aligned at the factory and phase corrected for stereo imaging.
ATC's drivers are manufactured in-house to exacting tolerances and are known for their innovations, such as the SL magnet system and the company's Soft Dome mid-range driver, which achieves broad and even dispersion to produce a flat response anywhere in the room. Situated in Aston Down in rural Gloucestershire, England, ATC was established in London in 1974 by acoustics engineer and musician Bill Woodman.
