AA50PHD | 3-INPUT 50W MIXER AMPLIFIER WITH AUTOMATIC SYSTEM TEST (PHD)

The AtlasIED AA50PHD is a 4-input, 50-watt mixer amplifier designed for distributed business paging, background music, speech privacy, music-on-hold, and smaller commercial audio systems that need flexible input control in a compact amplifier package. With one balanced mic/line/tel input, three unbalanced summing line inputs, phantom power support, remote input selection, remote level control, line output, preamp input, input-assignable Zone 2 output, and paging mute features, the AA50PHD gives integrators a practical solution for offices, retail spaces, schools, medical facilities, small restaurants, reception areas, and business audio installations.

A key benefit of the AA50PHD is its Push Here Diagnostic system, which helps test connected speaker lines after installation and identify common wiring or load issues before they become service problems. This is especially useful for 25V, 70.7V, and 4 ohm systems where speaker tap settings, wiring shorts, or incorrect load connections can delay commissioning. The AA50PHD is a strong fit when a project needs a compact AtlasIED mixer amplifier with dependable paging and BGM performance, remote wall plate control options, and built-in automatic system test support for cleaner setup and troubleshooting.
