KM-201 HDMI Karaoke Audio Mixer

I purchased this item solely to use the HDMI to HDMI signal path. The basic function does work, that it blends the microphone signals with the input HDMI source. There are however 2 major problems, that render the unit unusable in such configuration:1. There is slight delay of about 500ms, which results in amplified voice being behind2. There is a significant hum added to the HDMI signal (this is much less of a problem, than #1, but still significant)

Bought this because it's the only karaoke mixer that has HDMI ports for use with my apple TV and receiver at home. I was a bit dissappointed at the performance of this mixer. It buzzes loudly (emits a buzzing noise through my speakers) when I place it next to some of the other electronic devices in my living room (apple tv and xbox) -- the buzzing diminished to an tolerable level when I moved it away from the other devices. I would have put up with that, but what I could not put up with was the fact that the dynamic range of this mixer is very limited. Music and vocals that pass through this machine sound very "compressed" and "clipped" -- not very pleasing at all. The clipped effect takes the fun out of any karaoke party.

I was so excited when i got it hooked it up and BAM I was singing love how I changed the volume on the music so I can here my voice yet not so loud that I am singing over music. I got this after my Karaoke player went down I had all my Karaoke CD+G on my computer so why not try this instead of spending $400+ on a new Player. It works great, good tone. Can't wait to have friends over and have Karaoke night

I was so excited when I finally found an HDMI mixer! With all of the smart TVs and audio systems, this is greatly needed. It works, but only the basics. If you go from a simple source(laptop) directly to an audio/video device, then it works. I guess they did not advertise anything beyond that, so it does what it says. It does not support ARC or CEC. This was a big problem for me. I was successful at working around that and got the basic audio and video working, but the audio quality was not sufficient. I tried using the analog audio ports instead and got it working with better sound quality. There might have been a delay in both digital and analog configurations, but that is difficult to quantify, so I would say there is no noticeable delay. I was considering sending it back due to the HDMI shortcomings. After inviting a couple people over for a second opinion, and singing karaoke till 2 am, I decided it was worth the money. It's all about expectation management.

Is working OK for what I wanted to do...add mics to a HDMI Chromecast connection. I have not used the included mics, but have a simple Pyle wireless setup with a 8 input mixer. There doesn't seems to be a sync issue or delay on the Youtube video, but there is some noise from the mics. Hard to tell if it's just the mic, wireless feed, mixer, Acesonic or the whole package. I would say this should be about a $40-$50 product for what you get, but overall it does what it should.

I was hoping that I might get lucky with this inexpensive solution because of the ease of the HDMI integration, however I had to return it. The voice had a significant delay and was uncomfortably behind the music. Trying it on another TV and stereo system yielded the same results. I didn't expect greatness, but I did expect that at least it would function as advertised. Not ready for prime time.

I returned the product and i am glad. There are a couple of very fundamental problems in performance .. compared to what the product is expected to as a Karaoke mixer.1. Scenario 1 : I connnected a karaoke app on my laptop through HDMI In and had the mike that came with the product on mic 1 socket. Each time i sing using the mike, the karaoke volume would dip considerably and none of the volume controls helped. This is bad because I could get either the karaoke sound track or my vocals... only one at a time. Hardly karaoke2 Scenario 2 : I had a karaoke mike that has RCA output. I plugged it to the Acesonic mixer through the RCA in. The device did not even get recognized.Pretty disappointing because the two modes I use for Karaoke did not function.

It works as expected, and brings new fun activity to my family.
