Dave Rat On Equalization

[fleamail]

Mε αφορμή το δώρο της εβδομάδας και τις απορίες μερικών για το γραφικό equalizer παραθέτω ένα άρθρο του Dave Rat (Live ηχολήπτης στους RHCP, Pearl Jam, Mars Volta κ.α). Στο άρθο αναφαίρει τι διαδικασίες ακολουθεί ως προς τα Eq πρίν από κάθε Show.

 

I did a re tune on the PA today and actually flattened all the house EQ's and started fresh. I try not to do that as it means I have drifted, over time, away from from the sound I am looking for, I was not far off but enough that a fresh start was easier than trying to clean up. Some sound engineers come into each show and tune every day, I don't do that (anymore). I have found that if I pay carefully attention to the initial setup, I can fine tune for the room to room variations quite easily without losing the overall system EQ or altering my input EQ's. The way I go about system EQ is thus:

 

1) The EQ's on the sound console's inputs are to be used only to achieve the desired sound from the instrument/mic combination. Since the mics are the same every day and the band gear is the same everyday, I leave the EQ's on the sound console almost always exactly the same regardless of whether we play a stadium, arena or club show. The only time I should need to change input EQ's is if we change a mic type for some reason or there is a change in the backline's gear.

 

2) The system EQ's are to be used to achieve the desired sound from the PA system/venue combination. This is where the changes from room to room occur and for this duty I use two EQ's in series that divide it up one step further. One set of EQ's, the graphics, corrects for issues like room resonance's in the various rooms. The other set, the parametric's, are used to shape the tone of the system and gives me the ability to make the PA sound more Hi-Fi or warm and smooth etc.

 

All together the system EQ's and the channel EQ's create a sonic footprint that, if all goes as I attempt, forms a certain sound feel for the tour. I do my best to hold this 'sonic footprint' which is modeled after the album sound, together for the duration of the world tour. Worldwide sonic consistency is the goal.

 

Well, back to the re-EQ. I did a two step process and utilizing the advantage of having the dual PA system, I re-EQ' ed the inner system and left the outer as a comparative reference to assure improvement without losing the sonic theme. Now if I was a fan of digital EQ's, I could save the EQ curves and compare, but I am sticking with analog for now so I get to jump through some extra hoops. The outcome was all good, subtle difference but good. And not unlike fine tuning a race car, it will take some time to further refine and if all goes well, I hope to hold it together as long as the last one. Which was created in Barcelona.
