The AtlasIED E408-250 is built for installed audio engineers who need repeatable, fine-grain level control in 70.7V distributed systems. Whether deployed in sound masking grids, paging zones, or multi-room reinforcement networks, the ten-position non-shorting rotary switch gives technicians exact attenuation without accidental dead spots — a critical advantage over coarser two- or three-position volume controls found in lower-tier panel attenuators.
Rated at 250 watts and formatted for a standard two-gang wall plate, the E408-250 fits neatly into commercial installation environments where aesthetic consistency and code compliance both matter. The stainless steel plate meets UL813 and UL2043 safety listings, satisfying requirements for plenum-rated and fire-coded installations. Its AT Series electrical heritage means integrators can spec it alongside the broader AtlasIED AT line with confidence in matched performance characteristics.
For installations requiring rack deployment rather than wall mounting, AtlasIED offers the E408-250-RM as the rack-mount counterpart. The five-year warranty supports long-term service contracts common in commercial AV maintenance agreements.
