The Fohhn® AT-40 is an extremely powerful, high-capacity speaker system in a comparatively compact housing. It combines efficiency, speech intelligibility, sound quality and design at the highest level.

>Description<
The AT-40 is equipped with state-of-the-art time-aligned 12”/1.4” Neodymium speakers and is therefore extremely lightweight. It can be fitted with either an 80°x50° or 60°x50° rotating CD horn (HxV), depending on the application. A precision-made crossover with electronic high-frequency protection circuit is also integrated. The multiply birch wood housing is reinforced with steel brackets and equipped with 9x M8 and 3x M6 threaded inserts for safe installation in accordance with all current regulations. The AT-40 produces a perfect sound when combined with subwoofers AS-31 or AS-40 and operates as a fullrange or mid-high system.

>connector panel<
In low-impedance and 100V applications, the connector panel leaves nothing to be desired. 2 Speakon sockets and an 8-way Phoenix terminal strip with accompanying connector are available. If the terminal strip is used, the complete connecting panel can be covered so that only a single cable is visible. All connections to the 100V transformer are routed via the terminal strip and the two Speakon sockets.

>Applications<
Sport arenas, multi-functional halls, stadiums, theatres, musicals, theme parks, discos and similar venues.

>Weatherproof version (optional)<
Wooden Housing, special weatherproof plastic coating, impregnated speakers, design and dimensions unchanged.

High-performance 2-way passive speaker

High-performance 2-way passive speaker, equipped with one 12“-neodymium-sub-mid speaker and one 1,4“- neodymium HF-driver on a 90° revolvable CD horn in time-aligned speaker arrangement. The speaker is temporary able to work under 2000 W and generates acoustic pressure of maximal 131 dB. In a wide frequency range of 45 Hz to 20 kHz, the speaker has a defined dispersion of 80° x 50° or 60° x 50° (h x v). High-tensile multiplex birch wood enclosure with rounded sides, strutted with internal metal brackets to maintain safety instructions. Durable textured finish, available in black or white. Optional available in all RAL-colours or in weatherproof polyurethane-coating with impregnated speaker membranes. For the protection of the speaker chassis and the electronics, the enclosure is equipped with a ball impact resistant, extremely sound-permeable front grille, which is made of powder-coated steel and equipped with a moisture- and dust repellent acoustic foam in enclosure colour. Nine pieces M8 and three pieces M6 thread applications in ground, back and upper side are integrated to the admission of ring studs and system brackets. The loudspeaker system is optionally available with 100V technology in different performance classes up to 240 W. Connections: 2x Neutrik NL4 Speakon and pluggable 8-pin Phoenix terminal. The connections are sunk-in and protected below a cover on the back. All contacts exist twice, to connect very easy and safe to the next speaker. Specific brackets to assemble the system on ceilings, walls and traverses are available. Simulation data CAAD for ULYSSES and EASE are available.
