CHOOSING THE CORRECT AMPLIFICATION 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 Audio 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. TRx2115, TRx2153 & TRx2215 Connection Plate 1.
