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 the following
LG Smart TV
K036
Bose Soundbar 700
How can I make all three of these things to work together?
Hi @Raghu,
Since your TV has a Digital Audio output (optical), you 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)
By the way, I don’t understand what your second question is. The lyrics displayed from a web-based Karaoke site has nothing to do with the TV or the K036. Or is it just me misunderstood your second question?
Hi @Molly,
Plz 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,
I am trying to figure out how to connect the K036 mixer to my home stereo system. I have a Sony XBR-55X900F TV and a Yamaha Rx-V2600 receiver.
The TV has a Digital Audio output (optical) as well as an Audio out with a 3-pole stereo min jack.
The Yamaha receiver is connected to 5 speakers in the ceiling with the option of adding a subwoofer.
My questions:
1. How do you recommend connecting the K036 to the system?
2. I will be connecting a Windows PC/iPhone/iPad to display lyrics from a web-based Karaoke site. How do I disable the sound on the TV and pipe the mixer output to the receiver?
Please provide a picture of the recommended connections if possible.
Thank you for your help.
Thanks!
I have a Insigma Fire TV and an Onn blast 2.1 soundbar and the K036. The sound bar only has optical and aux output port. Please help me connect the youtube on tv to soundbar to K036 so that all sounds and karaoke comes out from soundbar and being able to use youtube on tv. Thank you!
