An audio signal distortion detection device for simplifying the detection of harmonic distortion to aid in setting an amplifier's gain control to match an audio source unit's output voltage. The audio signal distortion detection device generally includes a housing having a plurality of status indicators thereon for indicating the status of an audio signal being fed into the housing's audio input. By utilizing a scaling circuit and processing unit, the present invention may be configured to detect four audio frequencies and compare DC levels of the frequencies to each other to determine if harmonic distortion is present. A distortion illuminator will illuminate when such distortion is detected and thus significantly reduce the effort required to setting an amplifier's gain control.
A method of detecting harmonic distortion in an audio signal, comprising:

1. Field of the Invention
The present invention relates generally to an audio signal device and more specifically it relates to an audio signal distortion detection device for simplifying the detection of harmonic distortion to aid in setting an amplifier's gain control to match an audio source unit's output voltage.
Various other objects, features and attendant advantages of the present invention will become fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
FIG. 1 is a frontal upper perspective view of the present invention.
FIG. 2 is a rear upper perspective view of the present invention.
A. Overview.
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 3 illustrate an audio signal distortion detection device 10, which comprises a housing 12 having a plurality of status indicators 24, 25, 26, 27, 28 thereon for indicating the status of an audio signal being fed into the housing's 12 audio input 14. By utilizing a scaling circuit 52 and processing unit 50, the present invention may be configured to detect four audio frequencies and compare DC levels of the frequencies to each other to determine if harmonic distortion is present. A distortion illuminator 28 will illuminate when such distortion is detected and thus significantly reduce the effort required to setting an amplifier's gain control.
