Description

The AA50PHD is a four input channel mixer amplifier designed for distributed business paging and background music (BGM) systems, small to medium speech privacy systems, and in applications where music on hold (MOH) plus paging is required. With one microphone/line input and three stereo line inputs, the AA50PHD will accommodate a variety of input sources including paging microphones, media players, and digital music receivers. The AA50PHD includes a patent pending automatic system test, the Push Here Diagnostic (PHD).

What Sets the AAPHD Series Apart?

The PHD button is designed to check the connected loudspeaker lines for wiring and impedance errors. This test can be activated once all loudspeakers are connected and the circuit automatically verifies that the attached loudspeakers' tap settings do not exceed the amplifier's rated power, no loudspeakers are mistakenly tapped at 8?, and the loudspeaker wire is free from shorts.

The unit also incorporates a Remote Input Selection and Remote Level Control feature that allows the integrator to use a remote wall plate (AtlasIED model WPD-RISRL) and allow the user to select the input and adjust the volume from that wall plate up to 200 feet from the amplifier.

The AA50PHD provides 50-watts output power into 25V, 70.7V, or 4? loudspeaker systems. Rear panel DIP switch allows for creation of Zone 2 output using either Input 1, 2, 3 or 4. Unit can also be set-up to mute Inputs 2, 3, and 4 based on signal from Input 1 for paging applications where other input sources need to be muted during a page. Input 1 is either Mic or Line input selectable and Phantom Power is an option when using Input 1 Mic input.
