W4 4 Channel dj Bluetooth Audio Mixer with Effects, USB Interface, Stereo Recording, 48V Phantom Power，Sound Mixing Board for Live, Wedding, Party, Recording Broadcast

I bought this to use for karaoke whenever I host a party, so that I could use it as a standalone/ separate system just for vocals. It is connected to a power amplifier, a pair of speakers and 2 Shure Beta 58 A microphones. The music for the karaoke comes from a separate high-end system that I did not want to integrate with a unit of this lower caliber. It does what it says and does it pretty well. The housing feels solid and is made out of metal. It has a good weight to it. The sound is acceptable for just having fun with karaoke, and exceeded my expectations, and so did the built in effects. I am used to high end gear, but for the price and for my intended purpose, it's a steal and I don't have to worry about my nieces and nephews playing with it and tearing something expensive up after the adults are finished! The two negatives I found was that " some" of the pods/ knobs felt a little wobbly, but it's not as if there was any noise when they were turned. It also makes a pooping sound heard through the speakers when the power is turned on, so when turning it on be sure to turn your power amplifier on last. These are expected on a unit at this price and didn't surprise me. The unit is worth 2-3 times the price in my humble opinion.

It may be more useful to some and not so much to others.I use it at Church to get a separate mix for recording.I can take in two live mics and two lines from the board. Doesn't affect the audience sound, then I can also send a line to Facebook live and the digital recorder (HN 4).But the more I discover it has a lot packed in to the unit.
