1. What is Karaoke?

- Karaoke comes from the Japanese for  empty orchestra. Karaoke allows you to deliver your vocal mix with the music background.

You would be able to switch between vocal and non-vocal (music only). It is a great music entertainment for you to practice singing and relax or release stress.

2. What is Vocal/Non-vocal function for?

- Vocal is music and original singer's voice. Non-vocal (Music) is background music only. Having this function will give singers to choose either singing with instrumental music only or with a singer's voice. It is very helpful for beginners or anyone who would like to learn new songs.

3. What is CDG?

 CD+G (Compact Disc + Graphics) is different from a regular CD because it contains standard audio tracks that have graphics.  However, CD+Gs do not have video running in the background when the song is playing. It only shows the lyrics on screen with a solid color background.

BM-2000 machine: We use "random background" (such as scene of nature/ animals/ ocean). Customer can switch to different scene by press "Background" button on Remote Control. 

BM-3000 & BM-4000: They don't support CD+G files unless the file is already compressed into a music video file (such as vob., mpeg, wmv)

4. What is the difference of Amplifier and Mixing Amplifier?

- Instead of deliver sound directly to TV's speaker, amplifier is used to transfer sounds to speakers. Amplifier can gives power and better sound quality than using TV's speakers. We always suggest our customer to use a pair of home entertainment speakers instead of singing directly to TV. First, your outcome voice won't be delayed much comparing to directly connecting to TV and you can protect the speakers on your television.

- Mixing amplifier can deliver the depth and dynamic of your voice to the system, so you can have nearly full control of your outcome voice.  Indeed, basic amplifier can let you control echo, key, lower sound feedback for each individual microphone input. With mixing amplifier, you can control the volume of the music, and give the bass more power if you have a good pair of speakers.

5. What is Mixer?

- Mixer is used to control your microphone outcome sounds. There are echo, delay, tremble, base, key control on the mixer for you to manually adjust according to your needs.

6. Why there is No sound from Mic when using HDMI?

- Please note that the HDMI video and audio´s content are digital, while audio information (L/R) of AV component are analog. The audio from your microphone is also analog and therefore it cannot transfer the sound from microphone to the HDMI output. (refer to table below)

Cannot transfer sound through HDMI

AV Component


analog, able to transfer sound

Please note that most of Karaoke Player´s HDMI in the market are the same.  The purpose of HDMI is to provide better video quality, and sound because it is made for home theater, unfortunately it is not specified for singing/karaoke. Therefore, we suggest customer to use AV in order for microphone successfully transfer your voice into the system. 

Other option:    To enjoy HDMI High Definition video quality, you may consider of getting an Amplifier/Mixing Amplifier.

Having an Amplifier and Speaker system will also protect your TV´s speakers. Amplifier / Mixer are professional made for controlling the volume of Music as well as your sound (from Microphone). These devices can balance your sound before deliver your sound to the speakers. In contrast, when your sound is directly transfer from Microphone to TV´s Speakers, if the sound is too loud, your TV's speakers may be damaged
