The DX-388 G5 is the improved and upgraded karaoke amplifier from our popular DX-388 Beta and DX-388 D (G4) models. This DX-388 G5 model will have our most advanced and newest technology in our DX Series Karaoke amplifiers. Our engineers have developed a model with functions used by professionals and made it affordable for consumers like you to use at home. With the newly added features of 1 HDMI output, 3 HDMI inputs, and 4 independent signal outputs, these improved connectivity features will definitely create an unique KTV experience for all.

While keeping the integrity and quality of the original DX Series models, the improved DX-388 G5 will provide endless hours of powerful entertainment enjoyment. This new 5-Channel amplifier will be able to accept 3 separate HDMI inputs (Karaoke KTV Player, Computer, Cable / Satellite, Multi-Media Box) and other favorite devices like Bluetooth connection, a Multimedia Expansion Port that supports USB, a Blu-Ray Disc/DVD player and digital audio ports that support high quality Optical and Coaxial.

One of the new features on this model is the ability to auto process your karaoke music into separate outputs making it an excellent choice for connection to external speakers and subwoofers. For advanced users, the built-in processor can divide up the low frequency for the subwoofer, the vocal for the center speaker and the music for the side speakers. In addition to using the DX-388 G5 for KTV, this unit can also be used for High Energy Dance Music.

Like all the previous DX Series, this DX-388-G5 has the “Last Position” function that will default back to your last selection when you turned the power back on. This new model has 6 different Echo control functions to process your vocal voice with the standard 3 effect controls for Mic and Music. Once you get familiar with this amplifier, it will provide endless hours of amplified sound enjoyment.
