The AC75 is a passive 2 way loudspeaker designed for permanent installations. This low profile, high output, weather resistant speaker features a treated direct radiating 5.25” cone loudspeaker and a 1” direct radiating high frequency driver. The AC75 delivers reference monitor sound quality at high foreground levels and is designed for both horizontal and vertical installation. It is housed in a durable UV-resistant, paintable, all weather enclosure that is available in both black or white. The AC75 features an internal multi-tap transformer which allows 70V and 100V operation are direct 8 ohm bypass.
The AC75 features a tuned port Bass Reflex enclosure that has an improved low frequency response over a conventional enclosure. The integrated 70V/100V line matching transformer allows for parallel connection of multiple AC75 loudspeakers in distributed installations. The installer and system designer have a choice of 4 sensitivity settings (7.5W, 15W, 25W, and 8 ohm bypass) selected via a rotary switch located on the rear jack panel of the enclosure. These sensitivity or “tap” settings can also be used as a relative volume adjustment within the distributed system.
Included with the AC75 is a heavy gauge zinc plated and paint matched U-bracket for permanent installation. Threaded fasteners are available on the rear of the enclosure and can be used with optional ball-mount hardware.
One channel of discrete amplification and signal processing is required for this product. The preferred signal processors for the AC75 is the McCauley M Series family of loudspeaker controllers. The System Design Group can help in creating a complete amplification and signal processing solution.
