Alright, a couple of weeks ago i was mixing a hiphop act with a DJ and two vocalists in a small sized club (100 people). Suddenly a friend is coming to me, saying that one of the singers is just a little bit too loud and the other one is just a little bit too soft. I was standing at the mixing position and i thought the balance was ok but i walked into the audience to check it anyway. I listened near the bar and i heard the complete opposite, so then i thought ... panning?
I had the vocals panned just a little bit (10/20% to get a bit of separation), but apparently this resulted in two different (wrong) mix balances if you were standing right in front of one speaker (and not hearing the other side).
And after that evening i was just arguing with myself in my head ... why the fuck should i pan mono sources in a live situation anyway?
I like panning double mic's on a single cabinet hard left and right, but panning two guitarist fairly hard (50% or more) in a live situation means your audience on the left will hear guitarist 1 too loud, the audience in the middle will hear your desired effect/mix and the audience on the right will hear guitarist 2 too loud.
Why and when should i pan something? Because in most cases it means half of your audience is hearing something else then the other 50%.
Maybe i'm overthinking this a bit ... but it is just giving me a huge mindfuck at the moment.
