AAPHD Series Mixer Amplifiers

The AAPHD Series features five models ranging from 30-watts to 400-watts that are designed for use in 70.7V speaker systems. The AAPHD features a unique, patent-pending automatic system test using the front panel “Push Here Diagnostic” button. This internal circuitry 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 speaker’s 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. This allows for quick troubleshooting on site and after the sale.

Additionally, most models incorporate a Remote Input Selection feature that allows the user to select an input and control the volume level from an optional remote wall plate, model WPD-RISRL, that can be placed up to 200-feet away from the amplifier. Each unit also includes an ultra low noise floor, allowing them to deliver exceptional sound quality.
