Record Multitrack Audio with the Behringer XR18 (USB Setup Guide)

Behringer XR18 multitrack recording is one of the most powerful features this mixer has — and most people who own one never use it.

The XR18 includes a built-in 18×18 USB audio interface that streams all 16 mic/line inputs plus your stereo aux inputs directly to a computer. No external recorder. No splitters. No complicated routing. Just a USB cable, a laptop, and your DAW.

I use this setup with my five-piece band to capture rehearsals and live gigs — every channel, cleanly recorded, ready to remix or review after the show. This guide walks through the exact setup process from start to finish, including the routing decision that most people get wrong the first time.

Why Record Multitrack Audio with the Behringer XR18?

A stereo board mix is better than nothing, but it’s a one-shot capture. Whatever levels, EQ, and balance you had during the show is what you’re stuck with. If the kick drum was too loud or the vocals got buried in the second set, that’s permanent. The good news is that recording multitrack audio with the Behringer XR18 requires no external hardware beyond a USB cable and a laptop.

Multitrack recording gives you every channel isolated on its own track. After the show you can:

• Remix individual instruments with complete control
• Fix balance issues, EQ problems, or level mistakes from the gig
• Review performances in detail — useful for rehearsals especially
• Create polished live recordings for demos, social content, or releases
• Identify exactly which mic, channel, or signal caused a problem

For a band using the XR18 as your primary live mixer, adding multitrack recording costs you nothing extra. The capability is already built in — you just need to set it up correctly.

If you’re still evaluating whether the XR18 is the right mixer for your setup, our full Behringer XR18 review covers its strengths and real-world limitations for gigging musicians. And if you’re deciding between the XR18 and the other mixers in the lineup, our Behringer XR16 vs XR18 vs X32 Rack comparison breaks down which one makes sense for your band.

What You Need Before You Start

Hardware:

• Behringer XR18 (or XR16/X32 Rack — setup is similar)
• A laptop or desktop computer with a USB port
• A reliable, high-quality USB cable — the XR18 ships with one but replacing it with a quality cable eliminates a common source of dropout issues. Our guide on why cheap XLR cables fail applies equally to USB — cable quality matters more than most people think.
• An SSD on your recording computer (strongly recommended over HDD for reliability)

Software:

• The free X Air app from Behringer (for routing setup)
• A DAW — I personally use Reaper ($60 for a discounted license) and it’s my top recommendation for this setup. It handles 18 channels effortlessly, the routing is straightforward, and the price is hard to argue with for what you get. GarageBand (free on Mac), Logic Pro, and Ableton all work fine too if you’re already on one of those.

Windows users only:

• Download and install the XR18 ASIO USB driver from Behringer’s website before connecting the mixer

Mac users:

• No driver needed — the XR18 is class-compliant and macOS recognizes it automatically

Step 1: Set Your Sample Rate

Before your Behringer XR18 multitrack recording session begins, set your sample rate in the X Air app under Setup → Audio/MIDI.

Your two options:

• 44.1 kHz — standard for music-only projects
• 48 kHz — use this if your recordings will be synced to video

The critical thing here is consistency. Whatever sample rate you choose in the X Air app must match the sample rate in your DAW project settings. A mismatch causes pitch shifting, timing drift, and audio artifacts that are frustrating to diagnose after the fact. Set them once, set them the same, and leave them alone.

---

Step 2: Choose Your USB Routing (This Is the One That Trips People Up)

Getting USB routing right is what makes or breaks your Behringer XR18 multitrack recording — this is the step most people get wrong the first time.

In Setup → Audio/MIDI in the X Air app, you’ll see options for where the USB sends originate. This is the most important decision in the entire setup and the one most people get wrong.

Your options:

• Input (Pre-EQ) — the raw signal before any processing
• Post-EQ — signal after channel EQ is applied
• Post-Fader — signal after EQ, compression, and fader position

The right choice for almost every situation is Input (Pre-EQ).

Here’s why: recording pre-EQ means you capture a completely clean, unprocessed signal on every track. You can make any EQ, compression, or level decisions you want during the mix — both during the live show and afterward in your DAW — without those decisions being baked into the recording permanently.

This is especially useful for live situations where you’re making real-time adjustments during a performance. If you push a fader up because the guitarist needed to be louder in the house mix, that change won’t accidentally make the guitar too loud in your recorded multitrack. The recording is completely independent of your live mix decisions.

The only reason to choose Post-EQ or Post-Fader is if you specifically want to capture your live mix decisions as part of the recording — useful for capturing a specific live sound you’ve dialed in, but limiting for remix flexibility afterward.

Step 3: Connect and Configure Your DAW

Connect the XR18 via USB

Run a USB cable from the rear USB port on the XR18 to your laptop or desktop. Once connected, open your DAW and set the audio interface to the XR18. You should see up to 18 input channels available.

Create your tracks

Set up one mono audio track per input channel in your DAW:

• Tracks 1–16: XR18 mic/line input channels
• Tracks 17–18: Stereo aux inputs (useful if you’re running a keyboard, backing track, or any stereo source through the aux)

Label your channels first — this saves time

Before you start recording, name your XR18 channels in the X Air app (Lead Vocal, Snare Top, Bass DI, Guitar L, etc.). Most modern DAWs automatically import these names when you set up your tracks. It takes two minutes before the session and saves significant time during editing and mixing afterward.

Arm tracks and do a line check

Arm all tracks for recording, do a quick run-through to confirm signal on every channel, and check that nothing is clipping. You want peaks hitting around -18 to -12 dBFS on most channels — loud enough to capture cleanly, with enough headroom to handle the loudest moments of the performance without distorting.

Step 4: Recording While Running Live Sound

One of the best design decisions in the XR18 is that recording runs completely independently of your live mix. As long as USB routing is set to Input (Pre-EQ), you can:

• Adjust front-of-house EQ and channel processing freely
• Change individual monitor and IEM mixes mid-show
• Ride faders, mute channels, adjust effects
• Do anything else you’d normally do at the mixer during a show

None of it affects what’s being recorded. The recording is capturing the raw input signal before any of those decisions are applied.

This is a significant practical advantage. It means one person can run sound and record simultaneously without the two tasks interfering with each other.

---

Step 5: Managing Latency and Buffer Settings

If you’re monitoring audio through the computer rather than through the XR18’s own mix outputs, you’ll need to manage your buffer size:

• 128–256 samples is a good starting point for most setups
• Increase the buffer if you hear clicks, pops, or dropouts
• Decrease it if you need lower latency for real-time monitoring

For live recording where you’re monitoring through the XR18’s own outputs (the normal setup for a live show), latency settings in the DAW don’t affect what you hear on stage. You only need to worry about buffer size if you’re routing audio back through the computer for monitoring.

For most live recording scenarios, leave the buffer at 256 samples and don’t touch it.

---

Step 6: After the Show

Once you’ve finished recording, the most important thing to do immediately is save your DAW session and back up the files. Don’t wait. Recording sessions have a way of disappearing to accidental overwrites, software crashes, and human error. Back up to an external drive or cloud storage before you pack up the gear.

After the backup, your session is ready for mixing. Each channel is isolated on its own track with a clean, unprocessed signal. You can now:

• Apply EQ, compression, and effects in your DAW with full flexibility
• Adjust levels without being locked into the live mix balance
• Edit out sections, fix timing issues, or comp multiple takes if you recorded multiple run-throughs at rehearsal
• Export a stereo mix, individual stems, or a polished live recording

Practical Tips for Reliable Sessions

These tips will help ensure your Behringer XR18 multitrack recording sessions are reliable every time

Use a dedicated recording laptop if possible. A laptop running only your DAW and the X Air app is more stable than one with browsers, email, and other applications running in the background. Close everything you don’t need before starting a session.

Disable sleep, hibernation, and power saving. A laptop going to sleep mid-recording is one of the most common causes of lost sessions. Turn off all power management settings before a recording session.

Use an SSD. Recording 18 channels simultaneously requires sustained write speeds that can challenge older spinning hard drives. An SSD eliminates this as a variable entirely.

Do a short test recording before the show. Run five minutes of a line check to confirm all channels are recording, nothing is clipping, and your DAW is stable. Fix problems before the performance, not during it.

Keep your USB cable short and clean. A high-quality cable under 10 feet is ideal for the XR18’s USB connection. Longer cables and cheap cables are a common cause of dropout issues that are easy to mistake for driver or software problems.

How Your Mic Choices Affect the Recording

One thing multitrack recording makes immediately obvious is microphone quality and placement. A stereo board mix blends everything together and hides a lot. An isolated track for each mic reveals exactly what each microphone is capturing — room noise, bleed from other instruments, handling noise, and frequency response differences between mics.

This is actually useful feedback for your live setup. Listening back to isolated tracks after a gig or rehearsal tells you things about your mic placement and choices that you can’t easily hear in a full live mix.

For vocal mics specifically, the difference between the SM58 and Beta 58A becomes very apparent on isolated tracks. Our Shure SM58 vs Beta 58A comparison covers how these mics differ both live and on recording. If you’re using condenser mics on any channels, our guide on dynamic vs condenser microphones for live vocals explains the tradeoffs that become especially relevant when you’re recording.

For a broader look at which mics work best across your whole stage setup, our best microphones for live bands guide covers vocals, guitar amps, drums, and everything else.

Managing Feedback Before and During Recording

Recording a live show means recording everything — including any feedback that happens during the performance. Getting your feedback situation under control before the show is important not just for the audience but for the quality of your recording.

The XR18’s built-in RTA and parametric EQ on every channel give you the tools to identify and eliminate problem frequencies before they become feedback events. Our guide on how to stop feedback on stage with the XR18 covers the exact settings and process we use before every show.

Proper gain staging is the other piece of this. Understanding how gain flows through the XR18 from preamp to channel to bus is what separates clean, well-recorded shows from sessions full of clipping and noise. Our gain staging for live sound guide is worth reading before your first multitrack session if you haven’t already.
