TRx Loudspeakers are designed to be used with professional power amplifiers
capable of producing the correct power into equivalent speaker loads. Care should
be taken to avoid amplifier clipping. Due to the fact that music signals have a high
peak-to-average “crest” factor, a lesser power amplifier driven into clipping is more
likely to damage a speaker than a higher power amplifier used within its ratings. When
an amplifier is over driven, its output waveform is clipped or squared off reducing
the crest factor. If an amplifier is extremely over driven, the output waveform can
approach that of a square wave. Under these extreme conditions, an amplifier is
capable of producing far more power than its un-distorted rated power output.
Carvin recommends an amplifier capable of producing at least the power rating of
the speaker up to 1.5 times the power rating of the speaker.
(See TECHNICAL SPECIFICATIONS).
Always turn on the amplifiers after the mixer and control systems have been
powered on. This will eliminate power peaks due to switch on surges which can
damage loudspeakers. When powering down the system, reverse the sequence and
switch off the power amplifiers first.
