2-channel vs 4-channel DJ mixers: which do you need?

Quick answer

If you'll only be DJing with two players, two turntables or two decks, a 2-channel mixer may be all you need. It's also more than enough to learn to DJ.

A 4-channel mixer starts to make sense when you want to use three or more sources, combine turntables and digital players, work with multiple decks, add acapellas or loops from another source, or connect samplers, drum machines, synthesisers or other equipment.

Musical style also plays a part, but how you build your mixes matters even more. One DJ can play techno perfectly well with two channels, while another may need three or four to work with layers and different elements at the same time.

Don't buy a 4-channel mixer because you think it's more professional. Choose four channels when the way you DJ needs more than two.

What does it actually mean for a mixer to have 2 or 4 channels?

Each channel lets you control one audio source independently.

In a simple setup, you might have:

Channel 1: left player

Channel 2: right player

Or:

Channel 1: left turntable

Channel 2: right turntable

In both cases, a 2-channel mixer covers the setup perfectly.

Four channels give you more possibilities:

Channel 1: turntable

Channel 2: turntable

Channel 3: digital player

Channel 4: drum machine

You could also connect four players, use multiple digital decks or create any other combination compatible with the mixer's inputs.

So the fundamental difference isn't that a 4-channel mixer is better. It simply lets you control more sources independently.

Are 2 channels enough to learn to DJ?

Yes.

You don't need four channels to learn beatmatching, Cue, gain, EQ, filters, musical structure and transitions.

In fact, if you're starting out and don't yet know what kind of setup you'll eventually use, a 2-channel mixer or controller can be a much more sensible choice.

You can focus on learning the fundamentals without paying for functions and channels you don't yet know you'll need.

There are excellent 2-channel mixers such as the Pioneer DJM-250MK2, Pioneer DJM-450 and Allen & Heath Xone:23. Even if you want a rotary experience, there are 2-channel options such as the Ecler WARM2.

Buying a 2-channel mixer doesn't mean you have to keep it forever, either.

If you start using more sources over time or the way you DJ changes, you can always sell it and move to a 4-channel model.

Will you only use two sources?

This is probably the simplest question you can ask yourself.

If you're sure your setup will be:

2 players + mixer

or:

2 turntables + mixer

and you have no intention of adding anything else, four channels probably won't offer you much extra.

Even as an experienced DJ, you can work perfectly well with two channels.

The difficulty comes when the answer is no longer so clear.

Perhaps you normally play on two turntables but occasionally want to use a CDJ to play digital music.

You now have three sources.

Perhaps you use two players but want a third deck available at certain points in your set.

Again, you need a third channel.

That's why you don't have to use four sources all the time for a 4-channel mixer to make sense. Sometimes, needing a third source is enough to justify the step up.

What music do you play, and how do you build your mixes?

Musical style can influence the number of channels you need, but we wouldn't make the decision based on genre alone.

Two techno DJs can have completely different needs.

One might work with two tracks, make long blends using EQ and filters, and never need a third channel.

Another might build sets using three decks, loops and several layers at the same time. In that case, extra channels make a considerable difference to the creative possibilities.

The same applies to other styles.

You can use two channels to play house, disco, techno, hip-hop or practically any genre. But you can also develop a mixing technique that incorporates acapellas, percussion, loops or elements from other sources.

So rather than only asking what music you play, ask yourself:

How many elements do I want to control at the same time?

Genre matters. The way you mix matters even more.

Turntables + digital: one of the main reasons to choose 4 channels

Hybrid setups are one of the situations where extra channels start to make the most sense.

Imagine you normally DJ with two turntables.

Two channels are enough.

But you want to add a digital player so you can bring in tracks you don't own on vinyl.

Your setup becomes:

Channel 1: turntable

Channel 2: turntable

Channel 3: CDJ or another player

At that point, a 2-channel mixer starts to limit you.

A very common example would be two Technics turntables alongside one or two digital players.

It can also work the other way round. Perhaps your main setup is two CDJs, but you want one or two turntables available for certain tracks.

If you know you want to combine vinyl and digital, a 4-channel mixer usually gives you much more freedom to build your setup.

If this is the kind of configuration you're putting together, see our Vinyl DJ setup buying guide: which turntables and mixer should you choose?.

Acapellas, loops and a third deck

Not every source has to be a main player.

You can use two channels for the tracks you're mixing and reserve a third for an acapella.

Or load a loop on a third deck and keep it playing while you mix between the other two.

You can also use an extra channel for percussion or other elements you want to bring in at specific moments.

Here's an important difference.

With two channels, you usually follow a fairly clear pattern: one track comes in as the other goes out.

With three or four channels, you can start building the mix from simultaneous layers.

That doesn't make it better. It simply opens up a different way to DJ.

If you know this kind of workflow interests you, a 4-channel mixer starts to make much more sense.

Samplers, drum machines and other external instruments

Extra channels are also particularly useful when your setup goes beyond players or turntables alone.

You might want to connect a drum machine, a sampler, a synthesiser or another external audio source.

For example:

Channel 1: player

Channel 2: player

Channel 3: drum machine

Channel 4: sampler

Here, the mixer starts to become the centre of a hybrid setup.

Not every external device necessarily has to connect to a conventional channel, and your options will depend on each mixer's routing and connections. But as a general rule, the more independent elements you want to incorporate, the more useful extra channels become.

If your medium-term goal is to build a hybrid setup with external hardware, we'd probably look straight at mixers with 4 channels or more.

What if you use a DJ controller?

The same logic applies to controllers, although there are some differences.

A 2-channel controller is more than enough to get started and can also be enough for DJs who never need to work with more than two decks at once.

4-channel controllers let you work with more decks and, depending on the model, bring more sources into the mix.

But there's another detail to consider.

Some controllers let you control four decks using just two physical deck sections, with buttons to switch between Deck 1/3 and Deck 2/4.

That lets you work with four decks without necessarily having four physical players.

The experience isn't exactly the same, though. You need to remember which deck you're controlling at any given moment and switch between layers.

That's why we wouldn't automatically choose a 4-channel controller for a beginner, either.

If your initial goal is to learn to DJ with two decks, two channels are still enough.

Does it make sense to buy a 4-channel mixer for the future?

It depends on how clearly you know where you want to go.

If you're starting out and have no idea whether you'll ever use four channels, we wouldn't necessarily pay more just to have them “in case”.

Start with two.

Learn.

And when a real need arises, you can change your equipment.

But it's different if you already know where you want to take your setup.

Perhaps you have two players now but know you want to add two turntables.

Or you have two turntables and know you'll soon add digital players.

Or you want to start with two decks but eventually work with three decks and a drum machine.

In those cases, buying a 4-channel mixer from the start can save you having to replace it soon afterwards.

The distinction is between a hypothetical possibility and a real expansion plan.

Is it worth paying more for 4 channels?

At roughly the same product level, a 4-channel mixer usually costs considerably more than a 2-channel one.

That's why we don't think it makes sense to pay the difference simply because four channels look more professional.

If you'll never use more than two sources, buying a good 2-channel mixer may be better than choosing a 4-channel one just for the extra channels.

For example, someone who wants a compact home setup with two players may find everything they need in a DJM-450.

A DJ who only plays on two turntables may be perfectly well served by a Xone:23.

That changes when the extra channels meet a real need. At that point, they're no longer a feature you might use one day; they're part of your workflow.

So, a 2-channel or 4-channel mixer?

Choose 2 channels if:

You only use two sources.

You're starting out and want to learn the fundamentals.

You don't plan to expand your setup.

You want to keep your equipment simple and compact.

You'd rather spend your budget on a better 2-channel mixer than pay for channels you won't use.

Choose 4 channels if:

You want to use three or more sources.

You combine turntables and digital players.

You use a third or fourth deck for loops, acapellas or layering.

You want to add samplers, drum machines or other equipment.

You're building a hybrid setup.

You already know you'll expand your setup in the future.
