Excellent high quality karaoke setup for under $1000

For my Vietnamese wife a good karaoke setup is serious business. Problem is, I noticed that some people spend thousands of dollars on unnecessary stuff like gigantic receivers and speakers, only to end up with hiss, clipping, and clunky operation. Smart/consistent home setup should definitely fit under $1000, and that's with speakers and expensive Nvidia Shield box. You could definitely cut it to under $500 and still have a great setup. I did some research and put together a convenient setup for amazing quality at-home karaoke that isn't worth thousands, isn't a chore to operate, and passes Asian quality standards with flying colors.

How to use this setup once it's ready:

You find any song on your phone's Youtube and cast it to your TV
You pick up the microphone, start singing, and it all just sounds surprisingly beautiful

This guide assumes that you already have a TV with HDMI ARC or Optical/Coaxial audio output, and that you have WiFi at home. First thing is that you don't need 5.1, 7.1, 10.1 or anything else. We embrace stereo. Karaoke is stereo.

Now that you have everything, time to connect it

Setup your YouTube Box so that you can open YouTube app on your phone, and cast any video to your TV.
Important: If you plan on using HDMI ARC to export audio from your TV (not optical or coaxial cables), then DO NOT connect this box to the HDMI (ARC) port. Use any other HDMI port.
- Or if you have smart TV and you can cast youtube to it, ignore step one.
Plug in the power strip into nearby power outlet.
Plug in the HDMI audio extractor's power (USB).
Take HDMI cable, plug one end into HDMI audio extractor, the other into your TV's HDMI (ARC) slot. (Make sure it's the one that says ARC on it.)
(If you skipped HDMI audio extractor, plug your audio cable from TV audio out into the "3/4 (L/R)" on the mixer, and go to next step.) Take the first RCA to 1/4" cable. Plug the big end into the "3/4 (L/R)" ports on the mixer. Plug the small end into the "L/R" outs on the HDMI audio extractor.
Turn the tiny switch on the HDMI audio extractor to "ARC" mode (left) if you're using HDMI ARC as suggested here.
Now take the 2 speaker cables and plug them into the amplifier on one end, and speakers on the other. It doesn't matter if you use top or bottom ports on the back of your speakers, they're connected (DO NOT REMOVE THE BRACKETS THAT CONNECT THEM). Just make sure to color match the wires, and to make L / R actually correspond to your left and right speaker.
Take the second RCA to 1/4" cable. Plug the big end into the "Main Out" (top right) of your mixer. Plug the small end into the "inputs" of the amplifier.
Plug the amplifier into the power strip.
Plug the mixer into the power strip.
Take the XLR cable that came in the microphone stage kit. Plug it into 1 (left top) on the mixer, and into the microphone. (Make sure +48V button is NOT pressed).
On the top/middle of the mixer make sure that 3/4 USB button is NOT pressed.
Turn on your TV, amplifier (make sure the volume is at the bottom), mixer.
On your TV, check settings to make sure that it outputs the sound via ARC. If there's an audio format choice somewhere, set PCM.

Test it

At this point you should have a hot mic, just need to turn up a few knobs.

Turn the red Gain knob on the left strip of your mixer to about 90%.
Turn the white Level knob under it to about 70%.
Make sure all blue knobs on the mixer are in the middle (50%) position. We don't want to mess with equalizer yet.
Put the main volume slider on the right to about 80% position.
Start slowly turning the amplifier's volume knob and talking into the mic. You should start hearing the speakers. Success!
Cast something from your phone's YouTube app to play on the TV.
Mess with the Gain and Level knobs on the 3/4 strip until you hear the music from your speakers.
Sing and enjoy.
Bonus: try adding some lows on the mixer to the 3/4 channel, these speakers can surprise you.

Optional upgrades

What you need	Recommended item	Link	Why you need it
Speaker stands	Kanto SP26PL 26"	$120	Great stylish stands, very high quality.
Remove mic wire	Xvive U3	$200	Turn any dynamic mic into a wireless mic.
Add another mic	Shure SM58	$109	Sing together with someone.

As mentioned in this table, you could also splurge $200 on the Xvive U3, and get rid of that XLR microphone cable. Quality remains the same, but feels freeing.
