Atlas Sound GA-30T – Re-Entrant Horn 30W 70V Paging Loudspeaker

Product Overview

The Atlas Sound GA-30T is a 30-watt re-entrant horn loudspeaker with a combination 25V/70.7V line transformer, designed for voice paging, background music, and intercom transmission in commercial, industrial, and outdoor applications. This paging horn uses double re-entrant construction to maximize output efficiency and sound penetration through high ambient noise environments, making it a dependable choice for parking structures, warehouses, manufacturing floors, loading docks, and outdoor public address zones. IP56-rated for outdoor use in high-humidity environments.

Product Description

The GA-30T uses a compression driver with a ceramic magnet mounted to a round high-impact plastic horn designed to penetrate ambient sound levels in demanding environments. Double re-entrant horn geometry increases acoustic efficiency and directional dispersion compared to single-cone designs, making it effective where background noise levels are elevated. The combination 25V/70.7V transformer includes a multi-position knob switch for selecting power taps at 4, 8, 15, and 30 watts, allowing the installer to match speaker output to the required coverage zone without additional in-line attenuators. The unit also includes 8-ohm direct wiring for installations where a transformer is not required. A 60-degree dispersion pattern concentrates audio output within the coverage zone, limiting spillage into adjacent areas. The adjustable surface mounting bracket accommodates multiple vertical and horizontal positioning options, simplifying installation on walls, poles, and structural members. Each unit ships with 21-gauge 18-inch color-coded wire leads for polarity matching. The housing is gray with silver-colored hardware. The IP56 rating makes the GA-30T suitable for outdoor installations in rain and high-humidity environments. A 5-year warranty is included.

Key Features
