How to Set Up Sends and Returns in a DAW

Learning how to set up sends and returns is the moment your mixes start sounding cohesive instead of cluttered. Instead of loading a separate reverb on every track, you create one reverb on a return (or aux) channel and send a portion of each track to it. This shares one effect across many sources, saves CPU, and makes everything sit in the same space. The workflow is the same idea in every DAW, even though the labels differ.

Sends, returns and aux tracks explained

A send taps a copy of a track’s signal and routes it somewhere else, with a knob that sets how much you send. The destination is a return or aux channel that holds an effect such as reverb or delay. The effect’s output then flows into your mix. Because the send only copies the signal, the original (dry) track stays in place; you blend in the processed (wet) signal from the return. This is the heart of reverb and delay use, which we explore in how to use reverb and delay.

Why use sends instead of insert effects

• Consistency — multiple tracks sharing one reverb sound like they are in the same room.
• Efficiency — one reverb instance instead of ten saves processing power.
• Control — you adjust the overall effect level in one place and tweak each track’s send amount independently.

Insert effects still have their place, such as EQ and compression that should only affect one track. Sends are for time-based effects you want to share.

Step by step: create a return and send to it

1. Create a return / aux / FX channel. In Ableton Live you use a Return track; in Logic Pro and Pro Tools you create an Aux and route a Bus to it; in Cubase, Studio One, FL Studio and Reaper you add an FX or bus channel.
2. Insert your effect on that return, for example a reverb. Set the effect to 100% wet, since the dry signal already comes from the original track.
3. On a source track, add a send pointing to that return.
4. Turn up the send amount until you hear the right amount of reverb. Start subtle and add to taste.
5. Repeat the send on other tracks that should share the same space.

Set the return’s fader to control the overall wet level across everything feeding it.

Pre-fader versus post-fader sends

Most sends are post-fader, meaning the send level follows the track’s volume fader, so the effect fades with the track. Pre-fader sends ignore the fader and are useful for things like a dedicated headphone mix or parallel processing. For monitoring uses, see how to set up a headphone mix in a DAW. Getting your levels right first makes all of this predictable, so review gain staging if your sends sound too hot.

Common send-and-return setups

A typical mix has a few returns ready to go: a short reverb for tightness, a longer reverb for depth, and a delay. You can even feed one return into another, such as sending a vocal delay into a reverb so the echoes sound distant. Keeping these labelled and colour-coded helps, as discussed in how to organize a DAW project. If you build the same returns every time, bake them into a template using how to create a DAW template.

Frequently asked questions

Should the reverb on a return be 100% wet?

Yes. On a send-and-return setup the dry signal already comes from the original track, so the return should output only the processed (wet) sound. Mixing dry into the return as well just doubles the dry signal and muddies the balance.

What is the difference between a send and an insert?

An insert effect processes the entire signal of one track in series. A send copies a portion of the signal to a separate channel, letting many tracks share one effect and letting you blend dry and wet independently.

Why is my send effect too loud or too quiet?

Check both the send knob on the source track and the fader on the return channel. The send sets how much goes in; the return fader sets the overall level coming back. Also confirm whether the send is pre- or post-fader, as that changes how it tracks the volume.
