9.4 TESTING AND TEST SIGNALS
(Refer to CHAPTER 12 for troubleshooting methods)
To test a full-range loudspeaker or subwoofer or to reproduce test signals or tones through it for other purposes,
certain precautions must be followed to avoid damage to the loudspeakers. Generally sine waves, swept tones, pink
noise, white noise, and other constant volume test signals are much harder on a loudspeaker than normal program
material and therefore the potential for damage is much greater.
When using any of the test signals mentioned or similar test signals, never use power inputs that exceed 25% of the
loudspeaker’s RMS rating and do not test at this 25% level for more than a few moments. If test signals must be used
for extended periods of time, the power input to the loudspeaker should be kept below 10% of the loudspeaker’s
RMS rating to ensure the loudspeaker will not be damaged.
