SKU : DX-3000



Better Music Builder DX-3000 audio/video effect processor was originally developed by our engineering team in California . The DX-3000 uses the state-of-art technology by integrating a CPU controlled High performance 24-bit multi-engine Audio Video Karaoke Effect Processor, allowing for more features and details effect adjustment and customizations, making the DX-3000 High Quality CPU Mixer part of a complete, easy-to-use sound system.

The DX-3000 audio/video effect processor enable more unique music and microphone sound effects, which include personal microphone setup, maximum music volume lockup, the ability to lock on personal favorite settings, and the ability to pre-amp for high-end quality mixer and also prevent audio equipment from burning and breakage.

DX-3000 has a Smart Auto Input Switching (SAIS) function that can be used by the KTV clubs to save manpower and the money in operation.
