Load diagnostics in an audio system is the detection of proper connections of the loudspeaker and the wires connecting the amplifier to the loudspeaker. This training discusses DC and AC load diagnostics using the TAS6424-Q1 75-W 2.1-MHz digital input 4-channel automotive Class-D audio amplifier. In this training, you will gain a better understanding of the design need for AC and DC load diagnostics, how load diagnostics are measured and the circuitry.
