Better Music Builder DX-288 is the second generation of CPU-controlled Karaoke powered mixing amplifier with 700 Watts developed by their engineering team. It is a combination of the latest technology and innovative design. DX-288 is the first Karaoke powered mixing amplifier that can create a new Karaoke effect with 5 channels to enable an option for center speaker (for monitoring vocal). This creates a field of new dynamic environment while singing. DX-288 enables you to set up two main and rear speakers with an additional center speaker for special effects. It can cover up to an area of 2,000 square feet for indoor functions.
