AtlasIED AA100PHD 4-Input, 100W Mixer Amplifier with Automatic System Test (PHD)

Designed for commercial PA, security and AV applications, the AtlasIED AA100PHD mixer amplifier makes distributed paging, background music (BGM) and monitoring simple and dependable. This AtlasIED 100W mixer amplifier brings four inputs — including two mic/line channels with optional phantom power — so integrators can connect paging microphones, media players and digital receivers without compromise. The AA100PHD supports 25V, 70.7V or 4Ω speaker lines and includes an assignable Zone 2 output plus mute control for seamless paging over music.

What sets the AA100PHD apart is the patent-pending Push Here Diagnostic (PHD), an automatic system test that quickly checks speaker wiring, tap settings and short circuits to reduce install time and callbacks. Remote input selection and remote level control extend user access up to 200 feet, and contact-closure mute and preamp I/O make the unit ideal for security, surveillance paging and integrated monitoring systems. With a compact, rack-friendly footprint and a 3-year limited warranty, the AA100PHD is built for reliable day-to-day operation.
