INTRODUCTION
The DX-388 G3 Dynamic Fusion Amplifier is a new breed of
Better Music Builder mixing amplifier. This third generation
amplifier is a hybrid of power amplifier and mixer to help
you save space and achieve convenience.
The DX-388 Series has been widely praised as one of the
most user friendly mixing amplifiers. With its individualized
and diverse controls front and center, a karaoke novice can
be an experienced DJ in a matter of hours. Perhaps the most
impressive leap for this third generation mixing amplifier is its
accessibility. Besides the four composite A/V inputs in the
rear panel, a multimedia expansion bay is located in the
front for easy access. It allows playback of MP3 music files
stored on a USB flash drive and SD card.
The toughest thing to handle for a power amplifier is
clipping. Conventional designs use lots of negative feedback
to provide stability and lower distortion. Unfortunately this
method results in painfully audible distortion, because when
clipping occurs, this "feedback" can cause high-frequency
sticking, keeping the amplifier "latched" in the clipping state
longer than necessary. Abandoning conventional designs,
DX-388 G3 utilizes a new design to eliminate this
high-frequency sticking allowing the amplifier to remain
stable when powering high reactive loads.
It is simply the best solution for home and professional
karaoke performance.
