AtlasIED AA100PHD 4-Input 100W Mixer Amplifier With Auto Diagnostic

The AtlasIED AA100PHD targets commercial integrators building distributed audio systems for business environments — including paging, background music, speech privacy, and music-on-hold applications. With two balanced mic/line inputs supporting phantom power and two unbalanced stereo summing line inputs, it accommodates paging microphones, media players, and digital music receivers in a single rack unit, eliminating the need for an external preamp stage in most small-to-medium deployments.

What separates the AA100PHD from conventional mixer amplifiers in this class is its patent-pending Push Here Diagnostic (PHD) system. Once speakers are connected, a single button press runs an automated circuit verification that checks whether combined speaker tap settings exceed rated power, flags any speaker mistakenly wired at 8Ω, and confirms the speaker wire is free from shorts. This built-in commissioning tool reduces troubleshooting time on the jobsite and gives integrators a documented confidence check before handoff.

For facilities requiring user-level control without amplifier access, the AA100PHD supports AtlasIED's WPD-RISRL remote wall plate up to 200 feet away, enabling end-user input selection and volume adjustment from a discreet wall location. Rear-panel DIP switches configure a Zone 2 output from any combination of the four inputs and enable automatic muting of Inputs 2, 3, and 4 during Input 1 paging events — making this unit a practical single-box solution for office, retail, and hospitality installations requiring priority paging with background music integration.
