AtlasIED AT100 Single Gang 70.7V Commercial Volume Attenuator

The AtlasIED AT100 is a 100-watt single-gang wall attenuator designed for integrators and systems engineers deploying 25V and 70.7V distributed audio systems in commercial, institutional, and installed sound environments. Its auto transformer design achieves low insertion loss and extended frequency response — critical in multi-zone paging, background music, and life-safety audio applications where signal integrity across long cable runs cannot be compromised.

The ten make-before-break attenuation steps plus a positive off position protect the switch mechanism from damage during normal use, while silver-plated contacts ensure long-term reliability and noise-free performance in high-traffic installation sites such as offices, retail spaces, hospitality venues, and educational facilities. The removable terminal block simplifies field wiring and reduces installation time versus hardwired alternatives.

The AT100 ships with a stainless steel wall plate featuring a stamped and filled dial scale and skirted black knob, and mounts into standard single-gang electrical outlet boxes — making it compatible with virtually any North American rough-in without custom hardware. For integrators specifying aesthetic consistency across a project, white and ivory Decora-style plastic plate variants are also available within the AT model series.
