The Azusa Karaoke Mixer is a mixer, not a Karaoke machine; it doesn’t include any voice cancelling or karaoke file processing function. This gadget will allow you to mix the audio output from any device and the input of the two built-in microphone jacks (microphones are also included); the sound fusion can then be forwarded to regular speakers or a TV set. Individual controls for the volume of each microphone and the audio input allow you to balance your voice over your favorite song. The main audio volume control is in the back of the device which is a minus. Tone and echo controls will add some nuances to the voice, so it won’t sound flat. The mixer is lightweight but not necessarily portable; it needs 10 volts to function, so you cannot use a laptop USB port to power it. Cables are not included, so you probably will need to pick up some Y or RCA cables. Since you can stream many karaoke videos from the Internet, Azusa Karaoke Mixer is the only thing you will need to change your room into a big stage.

Update: I ordered 2 mixers and both came with 110-volt adapters, but this was a while ago. There are a lot of complaints regarding 220-volt adapters; you should try contacting the retailer. They were very helpful with some of my doubts when I contacted them prior placing my first order.

I was searching for a cheap, but quality, way to have karaoke at home or for gatherings. I used this mixer, laptop based software (karafun.com), TV, and existing surround system. This setup has worked great, and was even used at a Christmas party this year, then later borrowed by a coworker as well.

The unit seems built well, and sound is quite good for the price too. I find the tone knob basically pointless, and the mics will saturate if LOUDLY singing directly into them, but if managed properly even singers with powerful voices can use these with very good results. Also, there is a music mix knob on the back that is nice for balancing the mix from mics and incoming music levels. All in all this is a perfect component for a home karaoke system. Very happy I chose this product.

To anyone wondering about how flexible this unit is, the settings I use may be helpful.
1. Rear Music mix knob set to about 40% when connected to laptop headphone output set to 80% volume.
2. Tone set to zero
3. Echo – 2 seems about right, however for some songs or poor singers a bit more helps on long notes.
4. Mic levels – For VERY quite singers I open the know to full. For myself (I project very well and enjoy singing contemporary operatic styles, or things like Michael Buble) I set the mic to about 6 typically. This offers good levels with no saturation as long as the mic is held away or below the mouth.

My setup was as follows:

Laptop running karafun software connects from HDMI or VGA out to TV for video. The headphone jack of the laptop is run to the mixer box, via a 3.5mm to RCA cord, to supply the music and background singers, etc.

Next I connect the wall-wart of the mixer to the power and connect both mics to the front of the mixer box. Turn on the power switch located on the back of the mixer.

lastly I run another 3.5mm to RCA cable from the back of the mixer (RCA) to the audio input of the TV or sound system to be used (3.5mm in most cases when using VGA or HDMI of the TV, if going to a surround system you will probably need a RCA to RCA cord instead)

I typically test mic levels real quick, then set the music mix knob to about 40%, and run a test song to ensure music levels are not too low or drowning out vocals either. TADA!!! Karaoke time!!
