In large clubs the audience wont see what you use unless:
You have a really really tall laptop stand or you like to take CDJs and wink them in the air.
DJ booths in most big clubs have a screen so the audience will never see your gear and in most cases even funky lights in there. So all the audience will see is you moving your hand behind that screen or in those cases where the booth is embedded in the club more deeply people from a floor above you or to the side of you might see what you are using.
Also “the club standard” is becoming a thing of the past. In all the big clubs (Ministry of Sound, Octagon, Blue Lagoon, The Jungle, Cage, Gravity,…) that have a world class standing the new club standard is: You get sent the contact information of the on duty technician at least a week before your gig. He phones you up and you tell them what gear you bring and how you want it laid out in the booth. They tell you who plays before you and what they suggest for “handover”. You then arrive at the venue at least 3-4 hours before your gig and hand your stuff to the tech, who will have a chat with you. Then you go backstage and enjoy yourself until the assistant calls you to the booth.
Now yes this is world class clubs and you have to have a name to get that full package, but it basically is a boiled down version of that in most bigger clubs even if you are a noname (yet).
