GEQ ring out after auto eq

Ok let me dive into this forum.

Auto EQ process sets GEQ ( its magic!) but with all the abnormalities that can effect the process I still end going to the GEQ and making some adjustments to dial it in. Looking for large departures in EQ and listening to some dynamic music and then exercising my voice too...

Question is how do you accomplish the ring out process with the DRPA GEQ. Turn on mike, push the slider to performance volume and start pushing each range in the GEQ until you hear feedback? Or what....

    Sorry to be the bearer of bad news, but inside the only frequencies that you can trust from the Auto-EQ is from about 160 - 700. All others have to be tuned by ear.
    There are lots of good posts on the forum, search them out.
    Set up your system outdoors and auto EQ them transfer the info to the PEQ's to flatten it as close as possible. Then indoors should be a little easier because you'll only be fighting the room, not the room and the speakers.

  • Thanks for the reply

    I'll search \"auto eq\" area more throughly. Tons of information on the site so much so its hard to focus on a specific item sometimes...

    Lee,
    Your original question was:

    \"Question is how do you accomplish the ring out process with the DRPA GEQ. Turn on mike, push the slider to performance volume and start pushing each range in the GEQ until you hear feedback? Or what....\"

    Actually that is usually a process used in monitor world NOT front of house. A properly tuned system will be pretty immune to feedback till you get ridiculously loud. My opinion is, and has always been that the Auto EQ process is pretty useless indoors.
    1. because you CANNOT EQ a room! and Equalizing a room problem is a tradeout at best.
    2. All you can hope for from the Auto EQ is to use it to help get a flat system response in a reflection free area, (outdoors away from all reflective surfaces) the RTA is a poor tool to try and tune systems with since it doesn't take into consideration time, phase, coherence, but only frequency loudness of a given band, and with only 28 sample locations a LOT of the spectrum is ignored or \"carpet bombed in order to deal with a specific problem. ( I have had some good results with the \"new indoor EQ method\" @ the URL DRA suggested). That stored plot can then be used to \"see\" what a room is doing to your sound. The best thing then is to use creative speaker placement and aiming to get the energy of the performance on the AUDIENCE and off he reflective surfaces.

    Ringing out a room was the old way of seeing where the speakers excited the room the most. Todays emphasis is to have a properly tuned (essentially flat response, meaning equal energy to all frequencies across the audible spectrum ) system and once all the creative speaker placement and tuning tricks are tried, that loudness management is the single best method of problem resolution.

    I agree that the stuff is all over in this forum but getting it all together is a daunting task. and one that isn't very easy given the fact that we cannot post pictures to this \"new\" forum. Check out the FAQ's we are trying to organize the good info there...

  • Wow you guys just keep pushing the information forward here...!

    Dra

    I can't access the forum archives using the link you provided or by directly using the site pull down menu. It seems to get lost with the “/drug/� part of the link. I certainly want to review the info. Probably just a loose end from the site update process you guys are going through.

    You definitely caught me in a conceptual error with respect to using GEQ. New GEQ motto “flat is where it’s at�. Place emphasis on speaker placement and performance volume. GEQ adjustments should be made against established base line (outdoor eq process).

    I am still trying to figure out how to slide my system outside and execute the eq process without the neighbors going off the deep end…. But stranger things have happened around here. I understand this will base line the system.

    No doubt the organization and maintenance of this site is a huge undertaking but, I am sure I can speak for all when I say it is definitely appreciated… as is the time you folks take to respond to questions.

    Try this link.. it's one of the ones Dra pointed you too:

    As for the link Dra specified it works fine for me..

    Try the indoor method, one top only get it base lined and flattened. Then if you use subs, they would fall below the 170 hz \"use your ears to set up\" region, set crossover somewhere between 70 and 120 hz depending on tops.
