Standard 2-1984. Using audio band 20 Hz
to 20 kHz pink noise with peaks of four
times the RMS level, this strenuous test
signal assures the user that every portion
of this system can withstand today’s high
technology music. This rating is contingent
upon having a minimum of 3 dB of
amplifier headroom available.
Harmonic distortion
Second and third harmonic distortions
vs. frequency are plotted in figures 5 and
6 for two power levels. Ten percent (10%)
of rated input power and either one
percent (1%) of rated input power or one
Watt, whichever is greater. Distortion is
read from the graph as the difference
between the fundamental signal
(frequency response) and the desired
harmonic. As an example, a distortion
curve that is down 40 dB from the
fundamental is equivalent to 1% distortion.
Mounting
Warning: This unit is not designed for
overhead suspension
