Horns / Sound Projectors

Constant-Voltage Paging Projectors

PH10T / PH20T / PH30T
The economical, high-value Penton Audio PH Series paging projectors are well-designed, efficient, but economical. These 10, 20 and 30-watt double reentrant horns provide sound penetration and dependability seldom found in popularly priced models.

Each unit has a 70.7-volt transformer sealed inside its high-strength, lightweight, ABS housing that is protected against the elements by molded-in UV inhibitors. Its 17" five-conductor wire enters the housing through a gland nut designed to keep the moisture out.

All PH Series horns use lightweight high-density, phenolic-resin diaphragms and ceramic magnets.

This family is resistant to salt-laden air and is noncorrosive. Mounting is via an epoxy-coated, stainless steel "U" bracket held in place by stainless steel hardware, allowing its position to be maintained despite unusually high wind velocity.

The PH Series paging projectors are at home for indoor or outdoor situations. Unique applications for the PH horns is the ability to be installed near seashores made possible by the corrosive-resistant materials used in its design.

Their internal 70.7-volt transformers allow long wire runs without severe line loss and/or daisy-chained connection of multiple units to the same amplifier with 70.7-volt output.

Typical applications are schools, gas stations, industrial property, ballparks, factories, recreational districts, fairgrounds, air shows or wherever high efficiency and clear communication is of prime importance.
