DX-213 Karaoke Amplifier (Discontinued)


Better Music Builder Karaoke amplifier DX-213 is our latest amplifier with the main feature of having three channels. It is designed by the engineering team of Better Music Builder. Our engineering team has spent many years to conduct the research and collect opinions and feedbacks from the customers to design this unique product.

Based on our past experience, when the singer is getting too close to the speakers with the microphone, it would create distortion and feedback, which can damage the speakers. With the 3-channel feature of DX-213, the music comes from the main speaker while the microphone vocal comes from the center speaker. This can reduce the microphone feedback substantially.

You can also adjust the vocal and music effects from the center and main speakers (i.e. left and right speakers). Moreover, DX-213 has a special feature of vocal cancellation. It can eliminate the vocal signal from a regular audio CD for Karaoke singing. Therefore, you can sing Karaoke with any audio CD. The button to control the vocal cancellation in the front panel is very easy to operate. Therefore, DX-213 is the latest technological design for Karaoke amplifier and we are the pioneer in the market to produce such machine.
