  • Self diagnostic speaker load impedance testing system
    Patent number: 9838813
    Abstract: A self diagnostic loudspeaker load impedance testing system, or Push Here Diagnostic (PHD) system, located within a mixer/amplifier for testing loudspeaker connections to the mixer amplifier during installation and maintenance. The system includes a test signal source that replaces the normal audio input to the amplifier during test. A PHD analyzer within the mixer amplifier analyzes the response of the loudspeakers and related wiring to the test signal to detect a total system impedance that exceeds the amplifier rating and to detect short circuits in the wiring. The PHD analyzer illuminates an indicator when a fault occurs. The test is initiated by depressing a momentary contact switch within the mixer amplifier housing by inserting a tool through an opening in the mixer amplifier housing.
