The Blacka Acoustic SS Series Systems are designed to be used with professional power amplifiers capable of producing a minimum specifcation of 1100w - 2200w power output into 4 ohms.
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 loud speaker than a higher power amplifier used within its ratings. Primarily because music signals have a high peak to average crest factor. When an amplifier is severely overdriven its output waveform is clipped resulting in squared off peaks and thus 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.
