Atlas Sound AT10-PA – Priority 70V 10W Plate-Mounted Attenuator 3dB Steps

Product Overview

The Atlas Sound AT10-PA is a deluxe priority volume control attenuator for 70.7V distributed audio systems, rated at 10 watts with 3 dB step attenuation and a built-in SPDT priority relay. The priority relay overrides the attenuator's dial setting when triggered, delivering full program audio level to the connected speakers — a critical function in paging and emergency notification systems where speaker volume must not be user-limited during broadcasts. It mounts in standard 1-gang electrical boxes and is UL Listed for commercial installation.

Product Description

The AT10-PA is a plate-mounted attenuator for 70.7V commercial audio distribution systems. The priority relay is operated at 24 VDC drawing 10 mA, and is compatible with AtlasIED AA120M amplifiers that provide priority relay outputs. When a priority signal is received, the relay bypasses the attenuator's current volume position and passes the full incoming signal level to the speakers, ensuring that paging announcements and emergency audio reach the listener at the intended level regardless of the user's volume setting. Total attenuation range is 33 dB, adjustable in 3 dB increments, giving users meaningful but controlled volume adjustment. Terminations for both the relay and the attenuator are made through a removable terminal block for clean, serviceable wiring. The wall plate is stainless steel with a stamped and filled dial scale and a skirted black knob, consistent with the appearance of the broader AT series line. The unit fits into most standard 1-gang electrical boxes. A protective relay cover is included to safeguard relay contacts and ensure long-term reliability. Safety listings include UL813 and UL2043, and the unit carries a 60-month warranty.
