When it comes to using the FIFINE Karaoke microphone System in a home theater, there are basically two kinds of home theater: one is true surround sound speakers connected through an AV receiver, and the other is a soundbar. In this guide, we're talking about how to connect the FIFINE Karaoke microphone system based on two different situations.

Kind One: True Surrounds Setup Home Theater

True surround setup, specific to the AV receiver with the FIFINE K036 or K040 system. Because FIFINE karaoke systems use an 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 useless.

But if it is not a big issue for not having a true surround sound experience, there are two methods to connect with the AVR. The first one, we would call it a "one-source" setup, will mess up your current wiring. Therefore, if your AVR is connected with Blu-ray player, PS4, Xbox, and the like, you could look further below for the second method - "combination of video/audio input".

1️⃣One-source Method

First, instead of an HDMI source, such as the Roku and Apple TV inputs into the AVR, you have to get it onto the TV's HDMI and disconnect the HDMI ARC (if you use this connection).

Next, please identify the wiring connection point at the rear of your TV.

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. You can purchase this converter for it.

At last, just deliver the mixed audio of the mic and TV sound to the RCA IN jacks at the back of the AV receiver. And make sure you select the corresponding RCA mode.

Tutorial of the "One Source" Method

1. Smart TV+AV Receiver

TV has AUX OUT or RCA OUT

TV has only optical out or coaxial out

Notice: Converter Input: digital (optical/coaxial), output: analog (RCA).

2. TV Box/Chromecast/Roku+Smart TV+AV Receiver

TV has AUX OUT or RCA OUT
TV has only optical out or coaxial out

Notice: Converter Input: digital (optical/coaxial), output: analog (RCA).

3. PS4/Xbox+Smart TV+AV Receiver

TV has AUX OUT or RCA OUT
TV has only optical out or coaxial out

Notice: Converter Input: digital (optical/coaxial), output: analog (RCA).

4. Projector+Game Console/TV Box+Smart TV+AV Receiver

TV has AUX OUT or RCA OUT

TV has only optical out or coaxial out

Notice: Converter Input: digital (optical/coaxial), output: analog (RCA).

2️⃣Combination of video/audio input Method

First, you could keep your current setup unchanged.

Next, check the audio output connection of the source, such as the Roku, Apple TV box, or TV. If there is an RCA out, just take audio from this jack to K036 R+L in. If only an optical jack is available, then a converter is needed before the audio goes into K036.

Then, you need to look for the exact RCA jack at the back of the AV receiver to input K036. The input jack varies with different AVRs, and thus, the best way to find the correct input is to look for the user manual. Below is the Yamaha AVR for reference. In this case, you would need to hook up K036 to the AV 5, AV 6, AUDIO 1, or AUDIO 2 jack at the Yamaha receiver.

At last, change the setting of the AVR to have video input from HDMI while audio input from the analog jack (RCA where you connected K036).

Kind Two: Soundbar Setup

In a soundbar setup, another kind of home theater, you just need to look for the input jacks that are available on your soundbar.

If there is an RCA jack, then unplug the HDMI or optical connection from your TV. Next, look for the second step at the "one source" method above to connect TV with K036. At last, send the mixer audio from the K036 R+L OUT jack to the soundbar RCA in.
If there is only optical or HDMI (not HDMI ARC), the same as above: unwire the current setup and take reference from step 2 from "one source" method to hook up K036 and TV. At last, an analog-to-digital adapter is needed to connect K036 with the soundbar optical input.
If there is an 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.
