Need suggestion for audio mixer - 4K HDMI + Mic
In my current setup, HDMI from my FireTV Cube goes to my Yamaha AV Receiver. The HDMI video out from the receiver goes to my TV and the audio goes to my speakers.
HDMI in and out are all 4K.
Simple setup. Nothing special.
I now need to extend it for home theater karaoke. I need to mix the audio/video that comes out of YouTube app on Fire TV with two microphones (preferably UHF).
There are a couple of audio mixers on Amazon that take 4K HDMI and mix it with mic. However, from the reviews, it appears people are running into time lag issues. Also, the products seem to be obsolete.
These reviews are a bit outdated. I am wondering if there are newer audio mixers out there that can handle 4K HDMI plus mic with non-noticeable time delay.
Thank you in advance for your help.
