If you’re a content creator, having the right audio mixer can significantly simplify your workflow, particularly as your setup grows. The great news is that selecting the perfect one for your needs simply involves answering a few key questions.
What Are You Using the Mixer For?
Audio mixers are relatively straightforward: they merge multiple audio signals into a smaller number of outputs, generally speaking. However, they differ in several aspects, such as the number of input and output channels they offer, as well as additional built-in features ranging from basic equalization to advanced audio effects.
Although it may be tempting to buy a mixer with features you might use, it’s usually wiser to prioritize what you’ll use most frequently. For instance, if you’re producing a podcast, ample microphone inputs are essential. On the other hand, if your primary focus is recording from synthesizers, this won’t be as critical.
Selecting the Appropriate Number of Inputs
One of the most crucial factors when choosing an audio mixer is determining the number of inputs you’ll need. Consider your typical setup—do you require multiple microphones for podcasts, or several instrument inputs for music production? Planning for your current needs while allowing some flexibility for future expansion ensures your mixer remains a valuable tool as your projects grow.
When evaluating mixers, keep in mind that many advertised as “16-channel” often count both the left and right sides of stereo channels, inflating the number. While technically accurate, this doesn’t equate to having 16 fully independent channels.
There’s no strict “N+1” rule for choosing channels; instead, carefully review the input types and counts to ensure they fit your needs.
Lastly, remember that upgrading to a new mixer later is typically more expensive than investing in a slightly larger one upfront. If you’re uncertain about needing extra channels, it’s usually better to have them and not need them than to find yourself limited.
Microphone vs. Line vs. Instrument Inputs
The number of inputs on a mixer is important, but the types of connections those inputs use can be equally or even more critical.
Most audio mixers support either 1/4-inch jacks or XLR connections for microphones. While some mixers may offer instrument-level inputs for directly connecting a guitar or bass, this is generally a feature more common in audio interfaces than traditional mixers.
Be sure to choose a mixer that accommodates the specific connection types your gear requires to ensure a seamless setup.
Combination Jacks for Greater Flexibility
Many consumer-level audio mixers come with combination jacks that accommodate both 1/4-inch and XLR cables in a single input. This design provides valuable flexibility, allowing you to connect a variety of devices now while keeping your setup adaptable for future needs. Whether you’re plugging in a microphone, an instrument, or other audio equipment, these versatile jacks can be a game-changer.
Determining the Number of Outputs You Need
Choosing the right number of inputs for a mixer is straightforward—six microphones require six inputs. However, selecting the appropriate number of outputs can range from simple to complex, depending on your needs.
For most beginners, a stereo output will suffice, and nearly all mixers provide this standard functionality. If you’re purchasing your first mixer, this may be all you need to focus on.
That said, many modern mixers offer the capability to send stereo audio directly to a digital audio workstation (DAW) on your computer. While this feature won’t fully replace a dedicated audio interface, it can be a convenient addition for recording and editing audio digitally.
Built-in Effects
Depending on your intended use, having built-in effects in a mixer can be a valuable feature for enhancing audio signals. While these onboard effects may not compete with high-end hardware units costing thousands of dollars, they are often sufficient for most practical purposes.
Common built-in effects on consumer-level mixers include basic reverb, echo, and delay. Some models even offer more creative effects, such as AM radio simulation or pitch-shifting, depending on the manufacturer.
However, practical effects like compression are less common, as they typically work best on a per-channel basis. Mixers with per-channel compression do exist but tend to be significantly pricier than standard consumer models.
When an Audio Mixer Isn’t Necessary
An audio mixer isn’t always necessary. For most people, a few USB microphones combined with DAW software are more than enough. A mixer becomes essential when you need to combine multiple audio sources simultaneously.
For instance, if you’re miking up a drum kit or hosting a podcast with multiple participants, a mixer will help you manage those audio channels. However, before deciding on a mixer, carefully assess how much mixing you’ll actually need.
Additionally, keep in mind that mastering a mixer takes time, research, and practice. If you’re not prepared to dedicate the effort, a simpler setup might be the better choice.
