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.
Below is the illustrations of "one source" method:

Hi @Tamieko,
Sorry that we still need the exact model number so that we can google what kind of output TV has, RCA OUT or Optical OUT. For the former one, you can take TV sound from it to 3.5mm IN jack of K036. As for the latter one, you still need an optical to RCA converter, to change optical signal to RCA signal first. As for the soundbar, it always needs the 3.5mm male to 6.35mm male Audio Cable. ( The 6.35mm pin plug into the K036, the 3.5mm pin plug into the soundbar)
Plz reply us with the same account, then we can trace the record.
I still cannot figure this connection out. I have contacted you all once before and someone sent me a response but it really did not help. I have a Vizio sound bar. I have a Samsung Smart TV. Do I need the bar in order to use my K036? Can I just hook my K036 up to my TV? I would greatly appreciate any and all help. Please speak in a way a five year old would understand (seriously) because I have had this device for a while (several months) and have yet to use it. I am usually pretty good at connecting things and/or figuring things out but this one has left me completely stumped.
I have a samsung smart tv – UN58RU7100F
samsung soundbar – HW-R650
Hi oliver,
It will be better if you offer the TV and the sound bar model number, but we still can offer you the regular suggestion.
First you need to check what kind of output TV has, RCA OUT or Optical OUT. For the former one, you can take TV sound from it to 3.5mm IN jack of K036. As for the latter one, you still need an optical to RCA converter, to change optical signal to RCA signal first. As for the soundbar, it always needs the 3.5mm male to 6.35mm male Audio Cable. ( The 6.35mm pin plug into the K036, the 3.5mm pin plug into the soundbar)
Hello we recently purchased the K036. We were having a hard time setting it up and couldn’t connect the microphone to our smart tv and sound bar without losing the audio when we play music on youtube. The mics work fine but the audio comes out of the tv speaker and not the sound bar. Hope you could help me.
