Which mixing console should you buy for a home studio?
The answer is simple: none.
I agree: when we talk about recording studios, we often think of large mixing consoles, with all their buttons and sliders. So, for a home studio, it seems logical to lean towards the same kind of equipment, albeit in a more modest size.
On the other hand, it is true that for many people, it is more enjoyable to have a physical mixing console, with sliders that can be moved and adjusted.
Maybe that’s the case for you – for me, there’s no doubt. 🙂
However, we must face the facts: for a home studio, it is rarely the best choice.
Explanations…

Is a Mixing Console Necessary?
A mixing console, Wikipedia tells us, “is a tool used to mix (combine) multiple sources of music or any other audio signal.”
So, not really dedicated to recording, but rather to mixing different instruments and voices.
Indeed, the primary use of a mixing console is to manage the volume of each track separately. For example, you can raise the volume of the microphone on track 1 and lower that of track 2.
You can also manage the panning (or pan) of each track, meaning the position of the sound between left and right.
Useful for concerts… but what’s the point when you’re recording your music at home?
In concrete terms, none.
The fact is that mixing software today is extremely powerful. They allow you to make all these volume and pan adjustments, and much more.
It is therefore much smarter to record all instruments at the same level, and then mix them directly on your computer. This allows you to easily correct mistakes at any time!
And for that, you don’t need a mixing console! A simple audio interface is usually sufficient:

WHY A MIXING CONSOLE IS A BAD CHOICE
Preamps
Preamps are the electronic circuits that allow you to adjust the volume of your incoming audio signal.
To record instruments or microphones and achieve quality sound, you need good preamps. Otherwise, you risk losing definition, having noise issues, and other background sounds.
Between a mixing console with a built-in sound card (which can be connected via USB) and an audio interface, you may sometimes notice differences in quality in these preamplifiers.
Indeed, the console will contain several preamps, with a large number of other options and components. In contrast, at the same price, the interface will offer fewer options but with enhanced quality.
Equalizers
Most of the time, mixing consoles have a series of equalizers on each track, in the form of knobs allowing adjustments for bass, mids, and treble.
While they are very useful for managing multiple instruments in a concert or during a rehearsal, they become absolutely useless in a home studio.

Indeed, since they have few parameters, they will not allow you to make precise equalizations. So if you want to correct a specific frequency that resonates in your voice or guitar sound, it will be impossible.
On the other hand, this is exactly the type of adjustments you can easily make from your sequencer software with an equalization plugin. Your work will be more precise, easier, and above all, you can change your mind and modify the equalization without having to re-record everything.

USB Interface and Converters
To convert an audio signal into a digital signal understandable by the computer, you need to use what is called an analog-to-digital converter (AD/DA).
As with preamps, it is quite important that this is of good quality, so as to reproduce the sound in digital format as faithfully as possible.
Again, it is useful to question the quality of the components for a mixing console and an interface at the same price…
On the other hand, if you choose a non-USB mixing console, you will encounter other problems.
Indeed, to record your instruments, you will have to connect it to an audio interface. By adding an (ultimately unnecessary) link in the signal chain, you will thus increase the risks of background noise and quality loss, especially if one of the two devices is rather low-end.
Better to use an interface directly!
Effects
Moreover, mixing consoles often contain an effects module or the possibility to add external effects (Send FX). For example, reverbs or delays.

However, like equalizers, it is much better to add them in your software after recording. There are plenty of reverb plugins that will fully satisfy you.
Thus, in general, I recommend recording your instruments with as few effects as possible. This will give you more flexibility during your mixing.
It Takes Up Space!
You probably noticed that.
That said, my article wouldn’t be complete if I didn’t mention it: a mixing console is quite large. And heavy.
Much more than an audio interface.
So it’s a bit less convenient to transport and store. If your desk is already small, it can quickly become cumbersome. Don’t forget this aspect of the question.
What If I Need More Inputs?
It is true that many audio interfaces aimed at “home studios” only have two inputs. If you want to record a drum kit, you will need more inputs to connect all your microphones simultaneously.
Maybe that’s why you thought you needed a mixing console.
However, you have two other options that are much more suited to a home studio context.
The first is simply a more advanced interface, such as the Scarlett 18i20 from Focusrite, which has 8 inputs with preamps:

This is sufficient (and even too much) for a large number of home studio users.
Another option, if you have an interface that allows it, is to connect a multi-channel preamp like an Octopre via an ADAT cable, which will act as an extension of your interface:

With this, you add 8 additional inputs with preamps to your sound card. Plenty enough to cover most situations you will encounter.
In Summary
You will have understood, a mixing console is often unnecessary in a home studio.
Sure, there are always exceptions, but if you are just starting out, it’s just the best way to complicate your life.
And I must admit: I made the mistake of buying a mixing console a long time ago. And I would like to help you avoid making the same mistake 😉
So, even if they have fewer options, I recommend you lean towards audio interfaces. They are much more common in home studios and much more practical to use.
