Atlas Sound AT10D – Decora Plate 70.7V 10W Attenuator 3dB Steps
Product Overview
The Atlas Sound AT10D is a Decora-style, plate-mounted 70.7V auto-transformer attenuator rated at 10 watts for use in 25V and 70.7V distributed audio systems. It provides 33dB of total attenuation in ten make-before-break steps plus a positive off position, delivering reliable zone-level volume control in commercial, hospitality, and institutional AV installations. The unit mounts into standard single-gang electrical boxes and includes both white and ivory plates with matching skirted knobs for a finished residential or commercial appearance.
Product Description
The AT10D uses an auto-transformer design that provides excellent frequency response and low insertion loss compared to resistive attenuators, making it well suited for background music and paging distribution systems where audio fidelity matters. The ten-step make-before-break switching sequence ensures uninterrupted audio signal during volume adjustment, eliminating the pops and dropouts common with standard contact-closure designs. Silver-plated contacts deliver noise-free operation over the life of the unit. A removable terminal block simplifies wiring connections during installation and streamlines future service access. The Decora faceplate format is widely specified in modern commercial and healthcare construction, and both white and ivory plates are included to match common wall color standards. The unit fits most standard single-gang electrical outlet boxes, reducing the need for specialty back boxes. At 10 watts, this attenuator is appropriate for individual zone control applications where speaker tap power stays within this range. UL813 and UL2043 safety listings make it suitable for commercial occupancies, and the 60-month warranty reflects long-term reliability.
