    Each SHS-3T2-HD includes a single full-range driver housed in an enclosure providing high-quality sound. The transducer is attached to the SHS’s tunnel waveguide to take the sound performance to the next level. As the sound exits the waveguide, it travels through the patented adaptive dispersion lens that acts as a phase plug. The acoustic result is all frequencies are radiated evenly and annoying “hot spots” found directly below the speakers are minimized. This makes the SHS not only a great solution for sound and music reinforcement, but also a great sound masking speaker as well.

    The SHS-3T2-HD is designed to blind mount into hard deck ceilings with a minimum clearance of 3.5" above the ceiling deck. The specially designed expansion ring locks the speaker in place. Once installed in the ceiling, the speaker is concealed using a patented 3" diameter dispersion lens with a micro trim ring. Once installed, the visual appearance is reduced to the size of a high-end ceiling sprinkler head. The SHS-3T2-HD can become a true chameleon through AtlasIED’s DesignLab. AtlasIED offers custom color matching via UV printer that enables an integrator to submit an image or sample of the ceiling. Then, using a state-of-the-art print service, a custom lens and trim ring that matches the submitted sample will be shipped to the customer.

    The SHS-3T2-HD ships with the ability to utilize the Adaptive Dispersion Lens in three different configurations for various applications. Sound masking installations and installations with low ceilings (less than 10') should use the standard 4mm dispersion lens with solid lens cover attached. Installations with ceilings between 10' and 14' should use the standard 8mm dispersion lens with the solid lens cover attached. Installations with ceiling heights above 14' or in applications that require maximum intelligibility, the 4mm direct fire lens should be used with the direct fire grille attached.

    The SHS-3T2-HD can be connected to any 70V / 100V amplifier using standard 2-conductor commercial speaker wire with the included removable 4-pole euro style connector. Additionally, when used with an AtlasIED Z-Series High-Definition Acoustical System the speakers can be connected using Cat5e cable. Each SHS-3T2-HD features "in" and "out" Cat5e terminals making it easy to daisy chain speakers to the Z-Series source unit.
