General 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). The PHD button is designed to check the connected
speaker lines for wiring and impedance errors. This test can be activated
once all speakers are connected and the circuit automatically verifies
that the attached speakers' tap settings do not exceed the amplifier's
rated power, no speakers are mistakenly tapped at 8Ω, and the speaker
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 (Atlas Sound 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 4Ω
speaker 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.
