Atlas Sound BX-1A – Conduit and Cable Adapter for AP-30 Horn Speakers

Product Overview

The Atlas Sound BX-1A is a cast aluminum conduit and cable adapter cover plate for use with AP-30, AP-30T, APC-30T, APT-34AT, and APR-30AT series horn speakers. It provides a vandal-resistant connection point for armored cable and rigid conduit entries, threaded for 1/2-inch pipe thread. The BX-1A is the correct adapter for AP-30 series horns, which are commonly deployed in 70-volt distributed audio, paging, and mass notification systems across industrial, outdoor, and institutional environments. It is BAA and TAA compliant for government and public-sector use.

Product Description

The BX-1A replaces the standard cable entry on AP-30 series horn speakers with a threaded conduit fitting that accepts 1/2-inch pipe thread connectors. This adapter is required in installations where armored cable or rigid conduit is specified, including outdoor industrial sites, parking structures, transportation hubs, and institutional facilities where exposed cabling is not permitted by code or security requirements. Cast aluminum construction withstands vandalism and outdoor exposure without degradation. The 1/2-inch pipe thread size is compatible with standard EMT conduit fittings, reducing field procurement complexity. Compatible horn models span the AP-30, AP-30T, APC-30T, APT-34AT, and APR-30AT, all of which are widely used in commercial installed audio and emergency paging applications. The BX-1A and BX-2A (AP-15 series) are dimensionally different; installers should confirm the horn model before ordering. The 12-month warranty covers casting and thread integrity. No additional gasket is mentioned for the BX-1A; confirm field requirements before installation in wet or outdoor locations.
