How to Use FIFINE Karaoke Microphones System with A Home Theater
There are basically two kind of home theater, one is true surround sound speakers connected through AV receiver, the other is soundbar. The following tutorial is based on that two different situation.
True surround setup, specific to AV receiver with FIFINE K036, K040 system. Because FIFINE karaoke systems use analog stereo signal for in & out, including RCA, 3.5mm cable, etc. This kind of two-channel audio source will leave rear or ceiling speakers at no use. But if it is not a big issue for not having true surround sound experience, there are two methods to connect with AVR. The first one, we would call it "one-source" setup, will mess up your current wiring. Therefore, if your AVR is connected with Blue-ray player, PS4, Xbox and the like, you could look further below for the second method - "combination of video/audio input".
One-source Method
- There is RCA OUT (composite OUT). Then the TV audio can go from here to the "R+L In" jack of K036.
- If only optical output, an optical to RCA converter and an extra RCA to 3.5mm cable are needed. TV optical jack-converter-"R+L In" jack of K036. Purchase converter: http://amzn.to/2H7BaZ9
Combination of video/audio input Method

Note: If you are getting confused and cant follow the tutorial, please message us on our Facebook page or support email with your TV and AVR model number, we will give you the step by step instruction.
Soundbar setup, you just need to look for the input jacks that are available on your soundbar.
3.If there is optical and HDMI (specific HDMI ARC), unplug the HDMI ARC connection and use the optical connection. And the rest setup is the same as above.
If you have any problem or would like to suggest any other methods, feel free to contact us! Some illustrations are below.

Hello. We recently purchased the Fifine K306
Hi @Pravith K040 doesn’t have a input jack, so its receiver cannot be served as a mixer. And in you case where a mixer is necessary. Therefore you need one for the whole connection. TV (where PS4 or Apple TV connected to) and K040 to a mixer and out to a soudbar.
Just got the K040 wireless mic need help.
TV – VIZIO QLED
Mic system – K040
Sound Bar w/ Sub – JBL
K040 does not come with RCA connect only with 3.5 mm connection and XLR for antenna box. What would I need to get this to work as my home Karaoke setup?
Thanks in advance
I need help setting up my Fifine K040 to my Apple TV 4K (1st choice), PS4 (2nd), last my Sound Bar. Box does not have RCA connections. I don’t want to return and get an inferior product out there. Just want to simplify set up process so I can keep my new product. Help!

Hi @Noel Serrano what kind of HDMI splitter you use, can you send us the purchase link? Not sure what kind of HDMI splitter you refer to or any use of it. Since laptop should have their own HDMI jack, there’s no need for the splitter.
In normal case, keep your setup unchanged. But the audio should go from laptop 3.5mm output jack to K036 in jack, K036 out ot RCA jack at the back of your Sony AVR. Then go to playback device setting on your laptop, choose built-in speaker as defualt out.
You can message us at web@fifinemicrophone.com with the splitter info and your order number, we will give you the step by step instruction.
