Mixer Amplifier (PZA)

6-input, 200-watt power supply with automatic system test

The AA200PHD is a six-input channel mixer amplifier designed for distributed enterprise public address and background music (BGM) systems, medium to large sound masking systems, and applications where music on hold (MOH) plus PA is required. With four balanced mic/line inputs and two stereo summing line inputs, the AA200PHD will accommodate a variety of input sources, including PA microphones, media players, and digital music receivers.

The AA200PHD includes a patent-pending Push Here Diagnostic® (PHD) automatic system test. The PHD button is designed to check 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 tap configuration of the connected speakers does not exceed the amplifier's power rating, that no speaker is incorrectly tapped by 8 Ω, and that the speaker wire is free of shorts.
