70 Volt Distributed P.A. System Rentals

70 volt distributed systems are used in large outdoor venues where general purpose paging and medium quality music is required. 70 volt systems do not require large wire gauges and are capable of power large numbers of speakers over long distances such as race tracks and large outdoor events. DRD Audio custom designs its rental systems according to the application. Wireless systems are also available where laying out long wire runs is not an option.

Some of the recurring projects DRD A/V provides 70 volt distributed P.A. systems for in Northern Maine are harness racing, snowmobile racing and truck pulls. Also providing sound system and paging rentals to the Northern Maine Fair, Presque Isle; Houlton Fair, and Maine Potato Blossom Festival, Fort Fairfield.

Atlas DR-72

The U.S-made Atlas DR-72 horn with Atlas PD60T driver is the workhorse of DRD Audio's 70 Volt distributed system. At full rated power, a DR-72 can project up to 1/4 mile over flat terrain. Smaller horn projector sizes are available and used where suitable.

Full Range Paging Speakers

We use the Electrovice FC100 system to provide full range audio quality.  This 70 volt outdoor paging projector is designed with a driver that outputs sound in two directions, the back side of the driver fires into the main horn which is tuned to the lower frequencies - much like a woofer in a conventional speaker system - while the front part fires into a smaller horn tuned to provide higher frequencies, such as a tweeter in a conventional speaker system.  This creates an outdoor paging speaker suitable for music reproduction with a frequency range similar to conventional two-way speaker systems.
