DX-388 900W Professional Mixing Amplifier (Discontinued)


DX-388 is indeed a hybrid of power amplifier and mixer that can help you save more space and achieve convenience. It can produce the lowest level of feedback. It is designed to fulfill the amplification needs of almost any type of application. It also boasts some special features you would expect to pay for like adjustable built-in equalizer at different levels (i.e. Hi-EQ, Mid-EQ, and Low-EQ) enabling the microphone to adjust music key while you are singing Karaoke, subwoofer filtering, speaker-protecting limiter, etc. Perhaps the most important feature of the DX-388 Power Amplifier is the attention to detail in every aspect of designs.

DX-388 is based on real and proven design principles. The result of using proven design principles is a production of a power amplifier that can perform better than conventional designs when presented with adverse conditions. The design can also satisfy multi-uses for home Karaoke, Professional D.J., KTV rooms and equipment rental.

One of the most difficult things for a power amplifier to handle is clipping. Conventional designs use lots of negative feedback to provide stability and lower distortion. When clipping occurs, this “feedback” causes high-frequency sticking, keeping the amplifier “latched” in the clipping state longer than necessary. This results in painfully audible distortion. The design of DX-388 can eliminate this high-frequency sticking and allow the amplifier to remain stable when powering high reactive loads high volume level.
