Most audio mixers are built for audio professionals, such as musicians, live event producers and podcasters. As a live streamer, do you really need one?
While an audio mixer isn’t necessary to go live, it can significantly improve the quality of your stream. In this buying guide, we cover the features and attributes you should consider when purchasing an audio mixer, along with our six favorite audio mixers for live streaming.
Why do you need an audio mixer for streaming?
An audio mixer takes multiple sources of audio and mixes, balances and combines them into one signal. If you regularly use more than one microphone, play music or broadcast video gameplay on your streams, an audio mixer is a must for fine-tuning your sound. It lets you adjust the volumes of all your audio inputs, ensuring consistency.
With an audio mixer, you can manage multiple inputs at once. You can plug in your mic, mobile phone and laptop and control the sound and frequencies from each one. Here are some use cases for an audio mixer for streaming:
- Controlling the volume of background music
- Reducing feedback on a lapel mic
- Mixing sound for multiple guests on your stream
- Running a two-PC setup
- Streaming with XLR mics and a gaming console
- Streaming an event or conference with music and multiple speakers
If you don’t have multiple audio inputs, you probably don’t need an audio mixer. You can get an audio interface instead. But if you do plan to host a stream or broadcast an event that requires more than three or four audio sources, an audio mixer will help you control your sound.
Audio mixers work seamlessly with streaming software. If you’re using it for your live videos, you shouldn’t need to download separate Digital Audio Workstation (DAW) software to adjust your audio.
How to choose an audio mixer
When you’re in the market for a new audio mixer, there are several factors to keep in mind. Audio mixers come with different channels and tuning functions, and you’ll need to ensure you choose one that meets your requirements. Here’s what you should look for when deciding on an audio mixer.
Type: analog or digital
Audio mixers can be either analog or digital. Analog mixers are more affordable and easier to use than digital mixers because they have fewer buttons and dials. Those new to audio mixing appreciate the simplicity and efficiency of analog mixers. However, they lack the customization options of a digital audio mixer, and they tend to have fewer external device connections.
Digital mixers allow you to connect multiple devices and provide more options for tuning your audio. The digital audio transfer process also prevents white noise and buzzing that analog mixers tend not to block out. The downsides of digital audio mixers are that they’re much more expensive than analog mixers and the variety of customization options requires a bigger time investment.
The choice between analog or digital audio mixers comes down to your preference: convenience or customization. If you’re new to audio mixing, try analog first to learn the ropes.
Channels
On an audio mixer, a channel is a signal path; it’s what your audio travels on. You plug each of your sources into a channel, so the more channels you have, the more audio sources you can connect. Audio mixers with more channels cost more, so be certain of how many channels you need.
For live streaming, three channels are usually adequate — but your specific channel needs will depend on your setup.
Tuning
Controlling your sound is the reason you’re buying an audio mixer, so you want to be sure the tuning capabilities are in line with your goals. Look for audio mixers that let you control the channels, compression and equalization (EQ).
EQ knobs are usually things like bass, treble, etc., and they help you make the sound that the audience hears the same as the sound that goes into the microphone. Having enough tuning options is essential, but don’t let yourself get carried away and get an audio mixer with 20+ EQ knobs.
You might see some audio mixers advertised with “British” EQ. It means they were designed to emulate EQ circuits that were popular in England in the 1950s, 60s, and 70s and gave British rock bands of these eras their signature sound.
Microphone
You have to pair your audio mixer with the right type of microphone. If you use a USB mic that you normally plug directly into your computer, check that the mixer you purchase has a USB audio interface.
If you use an XLR mic for streaming, it needs phantom power to work. It’s called “phantom” power because it comes from the XLR cable rather than a power cord. Most XLR mics require 48V of phantom power, so make sure your audio mixer can supply at least that much.
Size
Audio mixers come in a wide range of sizes, from tiny to massive. Check the dimensions of a mixer before purchasing and be sure it fits in your workspace along with your other equipment. You want the audio mixer to be well within reach so you can make adjustments during your live stream.
Price
The cost will be a concern for most people purchasing an audio mixer. Prices vary considerably, with analog mixers tending to be less expensive than digital. Keep in mind that higher-quality audio mixers will cost more, and if you want extra functionalities, you’ll have to pay for them.
You can get a decent audio mixer for around $100. For higher-quality mixers with more capabilities, expect to pay closer to $300, or even up to $500 for the ultra high-end models.
