DIGITNOWPortable Karaoke Microphone Mixer System Set, with Dual UHF Wireless Mic, HDMI-ARC/Optical/AUX & HDMI In/Out in Singing Receiver for Smart TV, PC, KTV, Home Theater, Amplifier, Speaker

I came across this after hours of searching for an HDMI mixer with mic input (to no avail). My setup is simple and I didn’t want to change it:AppleTV to Soundbar to Projector via HDMII bought and inserted this mixer into things and everything worked flawlessly:AppleTV to This Mixer to Soundbar to Projector via HDMII expected to have to do some tweaks to audio delay, but nothing required. Truly plug and play.The mixer is not amazing but does its job - receiving wireless signal from mics and giving volume control of each mic, in addition to echo / reverb (a little always helps in karaoke) and tone (turn left for more bass, less treble/right for more treble, less bass).The mics are better quality than I expected. They’re not Shure, of course. But I’ve been to friends’ houses with karaoke machines with awful mics and these mics are closer to Shure quality than cheap karaoke system mics. These mics have a sturdy feel and decent sound.All in all, great solution to add karaoke to an existing tv and sound system!Note: I noticed low ratings seem to all complain about Bluetooth. Perhaps a consideration for some.Note 2: I will update this post if my positive experience changes.Note 3: for karaoke songs, I use Karafun (played on iPad and mirrored to alert AppleTV). High quality songs, consistent UI, and ability to control key and volume of lead and backup vocals. Highly recommend. In the rare instance they don’t have what I’m looking for, I search for the song name + karaoke on YouTube and that always works (but no key or volume control of vocals).

Sound quality is beyond my expectations. Wireless microphone is working good from the distance without breaking. Reverb quality is almost similar to the one that average karaoke studios have. It is fun to sing songs with it. Optical, HDMI, and Audio Jack are option for output. And HDMI and audio jack for input. You can take it to any places due to its small size with a sturdy metal boxing.Couple of things I want it to have are 1. rechargeable battery for the microphone. You need two AA size batteries to operate one mic but they don’t last that long. I wish I could charge the microphone while the device is not in use. 2. a travel case for storing the device and microphonesOther than that I am satisfied with the product. I don’t need to go Karaoke studio to sing! Or I can practice at home to sing my favorite songs more confidently at studio before my friends. Thing is my whole family spend more time together. Also I am very happy to see my teenager daughters enjoy their time with singing. Better than looking at their phones all the time.

Works Great! Love how easy this is to use for my home karaoke.

The audio track and video quality is good however, there is a very noticeable delay in the microphone. Makes using this unit as a karaoke mixer is very unpleasant. Not a good quality component mixer. I’ve had other karaoke machines with no voice delay. Anyone

My wife wanted to be able to sing karaoke with friends at home. I looked at a bunch of options but most of them did not do exactly what I wanted for her, which was to be able to hear the voices through my sound system while playing lyric videos off of youtube on the TV. The cheap 20$ mics do not do this, and I didn't want to bring out some big speaker every time.With this device, I bring it out when needed. I connect audio from the TV to this device using the 3.5mm jack, and then I connect the device to my speaker system using optical out. This allows me to play youtube videos on the TV, and hear all audio including voices and youtube out of the speakers together with very minimal delay.The only downside is the quality of the mics. It's a little hard to get a good clear output from the mics. You need to sing in a very specific way, practically swallowing the mics. Not exactly ideal for a post COVID world. I may look into upgrading the mics if possible, but for now this will do great for us, and is a great option for the price

We hooked these up and tried to get it working on a soundbar with an Apple TV using HDMI Arc and had significant delays from the mixer. However, switching to a true audio mixer these worked well enough. Wouldn’t recommend for anyone trying to get it setup for a soundbar. Also the mics notoriously cut on and off

Researched quite a bit and found that this setup was the most compatible with the existing LG TV and LG soundbar that I already have. Setting up the Mixer to work with everything else wasn't very straightforward, but I finally landed on the solution that balances audio quality (little to no delay) with aesthetics and ease of switching to and from karaoke to normal TV or streaming.I imagine similar set up can work for other branded TVs and Soundbars, but here are two potential methods for setting up that I settled upon after a fair bit of trial and error:1. (Recommended) a. Google Chromecast -> LG TV (HDMI non-ARC input), b. Mixer (HDMI ARC output) -> LG TV (HDMI ARC input), c. Mixer (Optical out) -> LG Soundbar (Optical in). While there was little to no delay in the mic input and music, this set up meant that I could no longer use my LG WOWCAST, which would otherwise connect by LG TV with LG Soundbar without the need for an HDMI or optical cable. Also, now if the Mixer is off, my normal TV sound output comes out through TV internal speakers; and therefore, if I want to use the Soundbar, the Mixer must be on with TV audio passing through the Mixer to the Soundbar.2. (Not recommended because of an annoying half second delay in audio from the mics): a. Google Chromecast -> Mixer (HDMI input), b. Mixer (HDMI ARC output) -> LG TV (HDMI non-ARC input), c. LG TV (HDMI ARC input) -> LG WOWCAST -> LG Soundbar (wirelessly using WOWCAST). While this meant that I only had one HDMI cable going from the Mixer to the TV, and no audio cables going to the Soundbar, it also had a significant audio delay that I could not seem to resolve via any settings or adjustments to my setup.
