• This machine is an advanced digital karaoke singing system, using dual microphone input system, independent microphone volume control, can be used in solo or duet singing.

• The microphone channels have sound quality adjustment functions, and you can get beautiful sound quality when using any grade microphone.

• When karaoke, the depth of reverberation is independently controlled, and the delay time can be adjusted steplessly, so that you can get a singing effect close to the professional level in karaoke.

• A large toroidal transformer is used in the machine. The toroidal transformer has many advantages such as high efficiency, small magnetic leakage, low internal resistance, and powerful energy when re-amplifying dynamic music.

• The signal input terminals are all advanced terminals, which are not easy to oxidize, and have very low contact resistance, which makes the audio signal more ideal for transmission.

• The karaoke amplifier circuit uses advanced digital large-scale integrated circuits for reverberation delay processing, the pre-amplification uses high-quality operational amplifiers, and the post-stage power amplifiers are high-speed transistor differential amplifiers.

• The music played back by this unit has high analysis, fast transient and dynamic sound effects.
