Care should be taken to avoid amplifier clipping. It is important to
understand that a low power amplifier driven into clipping is more likely to
damage a loudspeaker than a higher power amplifier used within its ratings.
This is because music signals have a high peak-to-average "crest" factor.
When an amplifier is severely overdriven, its output waveform is clipped (its
peaks are squared off) – reducing the crest factor. In extreme cases, the
waveform can approach that of a square wave. An amplifier is normally
capable of producing far more power under these conditions than its
undistorted rated power output.
The use of very high power amplifiers with outputs greater than those
recommended is discouraged.
Care should be taken to avoid switch-on surges, which can result in
momentary power peaks in excess of specified ratings. When powering up
a sound system it is important to switch on the amplifiers after the mixer
and control electronics have stabilised. When powering down the system,
reverse the sequence and switch off the amplifiers first.
