Total Harmonic Distortion + Noise (THD+N)
This function will give the total amount of distortion and noise in any given audio signal. The THD is
the unwanted audio that is not directly a part of an audio signal, however still harmonically related to
it. If a piece of equipment is perfect, the output should show no remnants of audio articles outside
the original signal. You’ll be hard-pressed to nd such a piece of equipment, however. In the case of
THD+N, not only are the signals directly related to the audio signal tested, but so are other bits and
pieces of audio that are not directly related to the signal. Noise, hum, buzz, RFI, and so forth are all
included in working out the THD+N value.
Measuring the THD+N:
1. Enter the THD+N function and choose SET to enter the settings menu. Here users can choose the
input source, unit (which is not directly important to the THD+N results, but is probably best set to
dBu for reference’s sake).
2. Set the input source to “Line in” and select OK to continue (gure 44).
