AtlasIED AA50PHD 50W Mixer Amplifier with Push Here Diagnostic®
The AtlasIED AA50PHD is a compact 50-watt mixer amplifier engineered for reliable performance in distributed paging, background music (BGM), speech privacy, and music-on-hold (MOH) applications. Designed for small to medium-sized commercial environments, this flexible solution supports 25V, 70.7V, or 4Ω speaker systems.
With four input channels—including one mic/line input with phantom power and three stereo line inputs—the AA50PHD accommodates paging microphones, digital music sources, and media players with ease. A standout feature is the Push Here Diagnostic® (PHD) system, which automatically tests speaker wiring, tap settings, and impedance to ensure safe and optimal installation.
Ideal for integrators, the AA50PHD supports remote input selection and volume control using a wall plate (Atlas Sound WPD-RISRL) up to 200 feet away. Rear panel DIP switches allow zone configuration and input priority muting, making it perfect for paging-over-music scenarios.
Whether you’re installing in a retail store, office, or waiting area, the AA50PHD delivers clean, reliable audio with installer-friendly diagnostics and flexible control options.
