Pick your model, so we can show you its steps. Pioneer XDJ-XZ, with an audio interface

Supported

  1. Connect the XDJ-XZ's MASTER2 output terminals (RCA) to your interface's inputs 1-2. That's your mix.
  2. Connect your interface's outputs 1-2 to the XDJ-XZ's LINE input terminals for CH3 (or CH4), as the rear panel marks them, and turn that channel's input selector to LINE. That channel is your partner's fader.
  3. Plug your speakers into your interface's outputs 3-4, or into this computer, not the XDJ-XZ's MASTER1.
  4. If your speakers are on outputs 3-4: in Audio MIDI Setup, select your interface, click Configure Speakers, and set it to Quadraphonic, so this Mac sees 4 outputs.
  5. At Your sound in and out, choose your interface: inputs 1-2 for your mix, outputs 1-2 for your partner, and your speakers.

Connect your Mac to your stack

  • Powered speakers: run a cable from your Mac's output (or your audio interface's outputs) straight into the speakers.
  • An amp and speakers: run the same cable into the amp's input. The amp drives your speakers as usual.
  • Not from your mixer's master out: your Mac plays the right sound at every point of a handover. And not Bluetooth or AirPlay: they add too much delay.

Interfaces that suit this setup

On a Mac

This setup needs an audio interface with two line inputs (for your mix) and two outputs (for your partner). If it has four outputs, your speakers can go on outputs 3-4. If it has two, plug your speakers into your computer.

MOTU M4 · 4 inputs and 4 line outputs, on TRS and on RCA.

Should work: It has what the app needs, but we haven't tried it yet.

Cables: one pair from your Pioneer XDJ-XZ's MASTER2 output terminals to the interface's inputs 1-2 (your mix), and one pair from the interface's outputs 1-2 to your Pioneer XDJ-XZ's LINE input terminals for CH3 (or CH4) (your partner). With the MOTU M4:

  • Pioneer XDJ-XZ MASTER2 output terminals (RCA) → MOTU M4 inputs 1-2: RCA to jack (¼")
  • MOTU M4 outputs 1-2 (RCA) → Pioneer XDJ-XZ LINE input terminals for CH3 (or CH4): RCA to RCA

Check what comes in the box. If these cables aren't in it, you'll need to buy them.

In a set, you'll see these buttons and messages:

  • READY · Set starts in · Handover · Accept handover · Partner mixed out · Fader up
  • You have control. Press Partner mixed out when you're in; your partner can stop their track.
  • Handover complete. Keep your track playing until your partner mixes you out.
  • Your partner has mixed you out. You can stop your track now.
  • After you've taken over, pull your partner's fader all the way down for 10 seconds, and they're told they can stop: the same as pressing Partner mixed out.
  • Your partner's fader is down. Push it up before you Accept.

Your internet

Use a wired connection if you can: an Ethernet cable from your computer to your router. Wi-Fi drops out more often, and a dropout can be heard in the set.

Upload speed: 5 Mbps or more, or quality may drop. The app checks both uploads when you link. On a slower upload, that DJ's part of their partner's recording is at the live sound's quality. If a connection slows during the set, the full-quality recording needs time to finish after you leave, up to 15 minutes; anything it can't finish by then is at the live sound's quality.

How a set sounds depends on both DJs' internet connections, which we don't control. We can't promise a connection will be good enough, so try a short set together first.
