Want to use your soundbar for karaoke, presentations, or announcements? Connecting a microphone can help, but not all soundbars can support a microphone out of the box. Some can pair with wireless microphones, while others need extra equipment to mix the audio before it reaches the soundbar.
If your soundbar doesn't support a microphone, you’ll need a microphone mixer to blend your voice with music or other audio. This guide covers the ways you can connect a microphone to a soundbar, whether you're planning a fun night of Karaoke or something more professional.

Soundbars That Support Microphones
Some soundbars are designed for karaoke and include wireless microphones in the box. These models handle both music and vocal audio, mixing them internally so you don’t need extra equipment. If you have one of these, setup is simple—turn on the microphone, make sure it’s paired with the soundbar, and start using it.
Most of these soundbars use Bluetooth or a dedicated wireless connection to link with the included microphones. They may also have built-in vocal effects like echo and reverb to enhance the sound. Some models even support additional microphones for duets or group singing.

Microphone Audio Mixers
If your soundbar doesn’t come with a microphone, it won’t have a way to process direct vocal input. In that case, you’ll need a microphone mixer to control the audio before it reaches the soundbar.
What Is a Microphone Mixer?
A microphone mixer is a small audio device that blends multiple audio sources into a single output. It takes input from a microphone and a music source (like a phone, tablet, or TV) and combines them so both can be played through the same speaker system. Some mixers have built-in sound effects like echo and reverb to improve vocal quality.
A mic mixer controls the connection between the microphone and the soundbar. It has separate input channels for the mic and the music source. You can adjust the volume levels independently, so your voice doesn’t get drowned out by the music. The mixer processes the audio and sends to the soundbar.
There are two main types of microphone mixers: Wired and Wireless.
Wired Mixers
Wired microphone mixers use physical cables. You connect the microphone to one input, the music device to another, and the output goes to the soundbar through AUX, RCA, or optical cables.
- Portable wired karaoke mixer
- Dual mic inputs
- Tone & echo control
- RCA input/output
- Home & stage use

Steps To Connect a Microphone
A microphone mixer is typically the best way to connect a microphone to a soundbar that doesn’t come with built-in wireless mics. I’ve used different mixers for karaoke setups, and while they all follow the same basic process, some work better than others depending on your soundbar’s inputs.
Step 1: Connect Your Microphone 🎤
Start by plugging your microphone into the mixer's mic input. If you're using a wired microphone, this is usually a standard XLR or 1/4-inch jack. If your mixer supports wireless microphones, pair the mic with the receiver and connect the receiver to the mixer's mic input. Some mixers allow multiple microphones, so if you're setting up for a duet or a group, check how many mic inputs are available.
I always recommend using a dynamic microphone instead of a condenser mic unless you have an external power source. Most mixers don’t provide phantom power, so a condenser mic won’t work unless you run it through an additional interface. If you're just doing karaoke, a simple handheld dynamic microphone works fine.
Step 2: Connect Your Music Source 🔊
Your mixer also needs a music source to blend with your vocals. You can connect a phone, tablet, or TV to play background tracks. Most mixers give you two options: Bluetooth or a wired connection like AUX (3.5mm), RCA, or optical.
If your mixer has Bluetooth, this is usually the easiest method. Pair your device, start playing music, and the mixer will combine the audio with your microphone input. The downside is that Bluetooth can introduce a slight delay, so if you notice any syncing issues, use a wired connection instead.
For a wired connection, AUX (3.5mm) or RCA works best. If you’re connecting from a TV, check if it has an AUX or RCA output. If it only has optical or HDMI ARC, you’ll need an adapter to convert the signal to something your mixer can use.
Step 3: Connect the Mixer to the Soundbar 🔌
Once you have your microphone and music source connected, it’s time to send the mixed audio to the soundbar. Most soundbars have AUX or RCA inputs, so use the corresponding output on your mixer. If your soundbar only has optical or HDMI inputs, you’ll need an adapter to convert the audio signal.
I’ve run into situations where a soundbar only has Bluetooth as an input option. In that case, you’ll need a Bluetooth transmitter connected to the mixer's output. This setup works, but Bluetooth adds a small delay, which can throw off live vocals. If you’re serious about sound quality, go for a wired connection.

Step 4: Adjust the Levels 📈
Before you start singing, take a moment to balance the audio. Your mixer will have separate volume controls for the microphone and the music. Start with the music at a comfortable level, then slowly bring up the microphone volume until your voice is clear but not overpowering.
Some mixers have built-in effects like echo and reverb, which can help improve vocal sound. I usually add a slight reverb to give the vocals a fuller sound, but too much can make things muddy. If your mixer has EQ controls, adjusting the treble and midrange can help your voice cut through the mix without raising the volume too much.
If the soundbar has its own volume controls, set them to about 75% and make most of your adjustments on the mixer. This prevents distortion and gives you more control over the audio balance.
Final Thoughts
A microphone mixer is the best way to connect a microphone to a soundbar that doesn’t support direct mic input. The setup process is simple, but choosing the right cables and connections makes a big difference.
If you’re planning to do karaoke often, we recommend investing in a good mixer with multiple inputs and sound effects for the best party experience.
