The AtlasIED AT100-RM is engineered for AV integrators and systems engineers who need clean, accessible attenuation control within equipment racks, cabinets, and consoles in 70.7V distributed audio installations. Eliminating a dedicated mounting plate in favor of a polycarbonate dial scale overlay allows the unit to drop directly into a rack panel cutout, keeping rack builds tight and professional.
Rated at 100W with 27dB of total attenuation in 3dB steps, the AT100-RM suits commercial installations in corporate AV, hospitality, houses of worship, and educational facilities where precise, repeatable volume management across multiple zones is required. The matte black overlay and skirted knob deliver a finished, uniform appearance that meets the expectations of installed environments visible to end clients.
Up to six AT100-RM units can be mounted on a single AtlasIED ATPLATE-052 rack plate, making this the practical choice when consolidating zone control for multi-speaker distributed systems into a single rack unit. Safety listings to UL 813 and UL 2043 support compliance requirements common in plenum-rated and commercial construction projects.
