ATLASIED AA35PHD 3-INPUT, 30-WATT MIXER AMPLIFIER WITH AUTOMATIC SYSTEM TEST (PHD)

The AAPHD35PHD Series features a patent pending Amplifier Diagnostic Test System. The “Push Hear Diagnostic” (PHD) test is simple to use and very effective in testing for speaker wire and load impedance faults in 70.7V systems. The PHD circuit can be activated using a small tool with a point to access the momentary switch through the hole on the front panel. This test circuit produces a test tone over the speakers analyzing multiple conditions to assure the amplifier is wired and loaded properly. The AA30PHD is a three 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 two stereo line inputs, the AA30PHD will accommodate a variety of input sources including paging microphones, media players, and digital music receivers. The AA30PHD 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 AA30PHD provides 30-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 2 or Input 3. Unit can also be set-up to mute Inputs 2 and 3 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.
