DJ headphone monitoring requires three controls: cue buttons, mix knob, and volume

The headphone monitoring section of a DJ mixer has three distinct elements, each serving a different role. (1) Cue buttons (one per channel) select which channel the DJ previews — pressing channel 2’s cue button routes channel 2 to headphones. (2) The headphone mix knob blends between the cue signal (channel being previewed) and the main output (what’s playing to the audience) in a single mono or stereo headphone mix. (3) The headphone volume knob adjusts the overall level to headphones. Some mixers additionally offer ‘split cue’: left ear hears one channel, right ear hears the other simultaneously. Confusing these controls — especially the mix knob — is the most common beginner difficulty, as it determines whether you’re hearing the cue channel, the master, or a blend.

Examples

Workflow: press cue button on incoming channel → use mix knob to hear that channel in headphones while main output plays the current track → adjust headphone volume → fade in when ready.

Assessment

Name the three headphone controls and the role of each. What happens if the mix knob is set fully to ‘master’? Fully to ‘cue’?
