Headphone Monitoring and Cueing
Preview before you play — the DJ superpower.
Your headphones are a private window into the next track. The cue mix is the most under-used knob in the booth.
// WHAT IT DOES
Headphones in DJing don't replace the speakers — they let you listen to the *next* track privately while the *current* track plays loud in the room. That's how you beatmatch and find the right place to start the new track before anyone in the room hears it.
Every DJ mixer has a 'Cue' button on each channel. Press it and that channel goes to your headphones (only). You can cue multiple channels at once to hear them blended privately.
There's also a 'Cue/Master' or 'Mix' knob on the headphone section. All the way left = only the cued track. All the way right = only the room mix. In the middle = blend of both, which is how most pros monitor live.
- • You can prepare a transition completely in private — find the , beatmatch, EQ it — before bringing it into the room.
- • Cueing both decks at once + Mix knob in the middle lets you hear your transition the way the crowd will hear it, before they hear it.
- • If the room PA blows up (cable falls out, channel dies), your headphones are your only confirmation that the music is still actually playing.
// SEE & HEAR IT
▸ HOW IT WORKS
- • Distortion in headphones — almost always headphone volume too high relative to source, not gain on the channel.
- • One ear quieter — bad TRS connection or worn jack. Twist the plug 90° to confirm.
- • Whether the kick on the cued deck and the kick on the room deck arrive together. That's beat phase alignment, audible in <30 ms of .
▸ WALKTHROUGH (5 steps)
- 1. DO: Plug headphones into the front of the mixer (1/4" TRS jack).▸ LISTEN: Silence — even if music is playing in the room. Nothing reaches the cue bus until you press a Cue button.
- 2. DO: Press Cue on channel 1 (with a track loaded and playing).▸ LISTEN: You hear that channel in your phones. Press it again to release.
- 3. DO: Set the Cue/Master mix knob fully to 'Cue' and slowly turn it toward 'Master'.▸ LISTEN: You hear the room mix bleed in. Park it at noon for a balanced monitor.
- 4. DO: Cue both channel 1 and channel 2 with both decks playing.▸ LISTEN: You hear both decks privately blended. This is how you check beatmatch before opening the channel fader to the room.
- 5. DO: Open the channel fader on the cued deck while the cue is still active.▸ LISTEN: Sound enters the room. Drop the Cue button — your phones now only carry the other deck (the next track), as it should be.
▸ COMMON MISTAKES
- ✗ Setting cue mix fully to 'Cue' so you can't hear the room — you lose situational awareness and a dropped PA goes unnoticed.
- ✗ Cranking headphone volume because the cued track is quiet. Fix the deck's gain, not the headphone amp.
- ✗ Wearing headphones over both ears all night. Your hearing budget runs out fast — use one cup off when you don't need to cue.
- ✗ Forgetting to release Cue on the outgoing track. That deck is then absent from your headphones when you need it.
