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:

I have Samsung TV only. No receivers or soundbars. Can I make it work with Youtube karaoke?
I have an lg tv with the opt plug and an lg soundbar, how do i get the mic to come out the soundbar? It only have aux, opt and bluetooth…having hard time
Hi alen.
The reason why YouTube app doesn’t work is that a device tranfers the signal to TV through the RCA port, so please cut out the connection of the RCA cable. Then you will be able to use the Youtube app.
As for the connection about TV, K036 and receiver. Here is the suggestion below.
First off, please cut out the connection you set up before.
The right method is : QLED smart TV→K036→Yamaha receiver
You need a Digital optical to Analog RCA converter, 2RCA Male to 3.5mm Male Audio Cable, to connect QLED smart TV with the K036. Then connect the K036 and Yamaha receiver, using 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 receiver AUX port)
Hi Alex.
First off, please cut out the direct connection between the TV and the receiver.
The right method is : LG 55SM8100AUA smart tv→K036→Yamaha Rx-v385 receiver.
You need a Digital optical to Analog RCA converter, 2RCA Male to 3.5mm Male Audio Cable, to connect LG TV with the K036. Then connect the K036 and Yamaha Rx-v385 receiver, using 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 receiver AUX port)
