5 AMPLIFICATION

Wavefront Touring loudspeakers are designed to be used with professional

power amplifiers capable of producing the following power outputs into 4

ohms:

W8C 400-550W

W8CS 700-1200W

WSX 550-1000W

W8CM 550-700W

W8CT 400-550W

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.
