If the input gain level is not reduced the built in limiter will activate During signal overload the limiter will reduce the input audio signal enough to minimize the amount of clipping A limiter takes the gain of an overloading signal and reduces it the reduction in gain reduces distortion that can cause damage to your speakers and amplifier During normal operation below clipping and momentary clips on peaks the limiter does not affect the audio signal and is inaudible It will allow brief clipping of peaks and will only activate when continuous hard clipping occurs During excessive clipping the limiter will reduce the audio signal enough to minimize the amount of clipping When the input signal decreases enough that clipping ends the limiter will deactivate and cease its gain reduction The limiter has a fixed threshold and can not be adjusted Safe Power Levels at Different Output Loads 8 Ohm Loads The amplifier can operate at practically any power level without risk of overheating However if it is pushed hard enough to continually light the CLIP indicator the amplifier s average output power can reach 150 watts 4 Ohm Loads H the CLIP indicator flashes occasionally the amplifier is approaching its maximum long term power capacity If it is lit about half the time the amplifier channel will probably go into thermal protection within a few minutes Short Circuit Protection The VLP Series amplifiers all come with built
