ALP-990i - ALP-990i series of professional audio power amplifier
Main Feature

ALESIS ALP series of professional audio power amplifier is based on the actual needs of engineers ALESIS AUDIO live sound and well-designed , high-quality components assembled , and by strict aging test , the amplifier is equipped with five high-precision protection circuit , to achieve the perfect boot protection prevents voltage surges and temperature protection prolonged use , occurs when outside speaker DC protection, as well as impact protection for the speaker switch , and signal distortion over the course of radiation protection limits set out to ensure that each amplifier has a very high stability. ALP Series amplifier driving force is strong, fast transient response , with damping factor greater than 400 , even though it is difficult to drive speakers can easily take office .
