Zone output
A zone output is a third feed, separate from master and booth, sending the mix elsewhere in the building: a bar, a smoking area, a second room, usually with its own level control.
In practice
Somebody is listening to your set at a level you cannot hear and cannot change. Mix as if the bar can hear you.
Not every mixer has one — it is a four-channel and installed-system feature rather than a battle-mixer one. Where it exists it is usually fed post-master and pre-limiter, so a clipped master reaches the bar clipped too. If a venue mentions a zone in the advance, treat it as a reason to keep dead air short: a gap that reads as a deliberate pause on the floor reads as a fault at the bar, where nobody can see you working.

Where it usually taps
Where these come from: How zone outputs are typically wired in installed club systems — conventional practice, not a catalog figure.
Why it matters
Zones exist because a venue is rarely one room. The bar wants the night audible at conversation level, the smoking area wants it quieter still, and neither should change when the floor gets louder. A zone feed lets the venue set those once and forget them.
For a DJ the practical consequence is that people are hearing you somewhere you cannot hear yourself, at a level you do not control. It is the reason a mic left open or a long silence between records travels further than you think, and the reason a venue may ask you not to pull the master down between tracks.
Frequently asked
Can I control the zone level from the booth?+
Rarely. On most installs the zone runs through the venue’s own amplifier and its level is set at the rack, not the mixer. Assume you cannot change it and ask the engineer if it matters.
Does the zone hear the microphone?+
If the mic is on the mixer and the zone taps the master, yes. That is how a private booth conversation ends up audible at the bar, so treat any live mic as live everywhere.
Which mixers have a zone output?+
Four-channel club mixers and installed rack units generally do; two-channel battle mixers generally do not. Check the rear panel during your advance rather than assuming from the model name.
Related terms
Master output
The master output is the mixer socket that feeds the room. Everything you do on the channels arrives there summed, and its level knob decides how hard the club system is driven by the mix as a whole.
Club sound system
A club sound system is the whole chain after the mixer: processor, amplifiers, subwoofers, main speakers and often delay or fill speakers, tuned together for one room by an engineer who is not in the booth.
DJ booth
The DJ booth is the space the equipment sits in: the table, the monitor, the power, and where all of it sits relative to the floor. It is part of the instrument, because it decides what you can hear.
Mic input
A mic input takes the very low signal a microphone produces and amplifies it to line level, with its own gain, usually its own two-band EQ, and on club mixers a talkover control that ducks the music while someone speaks.
