BMB DX-222  DIGITAL 500W MIXING AMPLIFIER

Better Music Builder DX-222 is the world’s first generation of CPU-controlled Karaoke Mixing Amplifier. This mixing amplifier uses the state-of-art technology by integrating a CPU processor inside the machine. Our engineers use this idea because it enables the machine to perform detailed task and have good control by using CPU technology. It can also produce excellent music source and vocal effects by a digital mixing powered amplifier with 500 Watts.

DX-222 is an incredible machine. The CPU features enable our engineers to develop more unique music and microphone sound effects, which include personal microphone setup, 3 digital sound effects that can be adjustable, the ability to lock on personal favorite settings, and the great stability to prevent the equipment from burning and breakage. That’s why it is great to buy a CPU-controlled mixing amplifier.
