Applications

FAP42T combines superior coaxial loudspeaker performance with wide dispersion and easy installation. A low profile enclosure and wide coverage make the FAP42T a perfect choice for low ceilings. The FAP42T will satisfy the needs of owners, architects, contractors, and consultants by delivering true, high fidelity sound reproduction in an attractive and easy-to-install system. The FAP42T is ideal for high-intelligibility voice, music, and signal reproduction in commercial, industrial, and institutional applications.

FAP42T-B

General Description

The FAP42T's 130° dispersion angle effectively reduces the number of loudspeakers necessary to achieve coverage in distributed systems with low ceilings.

The loudspeaker component matches the performance of the legendary Atlas Sound Strategy FA Series. High quality construction 4" coaxial cone type driver includes a 1" voice coil and polypropylene cone with a butyl rubber surround. The 19mm coaxially mounted tweeter is constructed of PEI. A high sensitivity level means less power may be required to achieve the desired SPL. This loudspeaker is factory assembled in an optimally tuned & ported deep drawn enclosure and includes a specially designed 16 Watt low saturation 70.7V / 100V transformer. A convenient front mounted selector switch allows tap selection without the need to remove the speaker from the ceiling. This switch also includes a transformer bypass setting for 8Ω direct coupled operation.

Mounting Accessories

Mounting is simplified with Strategy style "Dog Leg" tabs that allow easy installation into drop tile or drywall ceilings with provided tile bridge assembly. The tile bridge consists of two "V" shaped formed mounting rails and a C-Ring assembly. The C-Ring can be attached to the rails with the screws provided to extend support to the T-Bar grid in suspended ceiling applications. Multiple hole locations are provided to allow the C-Ring to be positioned to the outer edge the tile if necessary.

For existing dry-wall applications the tile bridge C-Ring and support rails can be inserted into the hole cut for the FAP42T. For easy positioning the "V" shaped support rails match the shape of the C-Ring tabs for easy maneuvering and location when working "blindly" above the deck

A uniquely designed "easy access" input panel on the side of the enclosure allows for "thru" conduit runs using flexible or rigid conduit. Below this cover resides a detachable Phoenix style locking four-pole connector which provides for easy daisy chain wiring to other full range 70.7V loudspeakers or Atlas Sound FASUB subwoofer. The package includes an attractive press-fit grille which nicely matches contemporary architecture.

For new construction drywall ceiling applications, the optional FAP42-TR trim ring is available. This unit provides a marked location for drywall installers to cut around essentially reserving the desired location in the ceiling until final installation of FAP42T. Mounting holes are provided to accommodate 16" or 24" OC stud / joist mounting.

A support ring is also provided on the top of the FAP42T enclosure to facilitate an auxiliary support cable.

NOTE: IT IS MANDATORY THAT THIS SECONDARY SUPPORT BE UTILIZED IN DROP CEILINGS FOR SAFETY AND SEISMIC CONSIDERATIONS).
