Atlas Sound AT100 – 100W Single Gang 70.7V Commercial Attenuator

Product Overview

The Atlas Sound AT100 is a 100-watt single-gang in-wall attenuator designed for 70.7V commercial distributed audio systems. It provides local volume control at the zone level, allowing building occupants to adjust audio levels without modifying central amplifier settings. Rated at 100 watts, the AT100 handles larger speaker zone loads than standard 35W attenuators, making it appropriate for higher-power commercial zones in offices, retail environments, and institutional facilities.

Product Description

The AT100 is Atlas Sound's high-capacity single-gang wall attenuator, engineered to deliver reliable zone-level volume control in demanding commercial 70.7V audio systems. With a 100-watt rating, it accommodates multi-speaker ceiling zones or individually powered high-wattage speakers that exceed the capacity of standard 35W wall controls. The rotary attenuation control provides smooth, continuous level adjustment, giving users intuitive control over the listening environment. Screw terminal connections allow secure, permanent wiring to the 70.7V speaker distribution line, and the single-gang form factor fits standard electrical boxes used in commercial construction. The AT100's transformer-based design maintains constant 70.7V line impedance regardless of the attenuator setting, which is essential for stable operation of the amplifier driving the distribution system. Its white finish coordinates with standard commercial wallplate systems, and it can be installed alongside other single-gang devices in multi-gang configurations using standard commercial wallplate covers. The AT100 is a straightforward, contractor-preferred volume control for systems where higher wattage per zone is required. It is commonly deployed in large conference rooms, gymnasiums, dining halls, and other spaces with multiple ceiling speakers on a single zone circuit.
