    You might use a dual channel FFT program like Systune or Smaart for that purpose. Join one of their classes to learn the ins and outs. This is nothing that can be explained in 5 sentences on a forum.

    See page 87: https://www.allen-heath.com/media/SQ_ReferenceGuide_V1_5_0.pdf

    If I recall correctly, you output the SigGen to L/R. Input the mic into any channel but do not assign it to L/R. PAFL the mic channel and use the RTA while adjusting the graphic EQ on the L/R to flatten out the frequency response. Remember to reduce the gain on problem frequencies only; do not boost. Do the same thing on other Aux mixes as needed.

    Hi Heirloom AVM,
    Thank you for your reply. I is so simple, I will follow the steps you just described to ringout my PA.
    So, to Tune my AUX, I just have to output SigGen to it (AUX)?

    Thanks

    Yes Willy, just output the SigGen to whatever AUX mix you are EQ’ing instead of L/R.

    For search and destroy of monitor feedback I’ll normally just open up the vocal mic
    for the given monitor mix, do a couple ole fashioned check 1 2’s push the level a bit
    till it starts to ring and notch a couple of the offending frequencies.

    The mains can be a variation of that and then a check with smart.

    Using the spectrograph function on the mixer would be better than the RTA.

    Can you please describe step by step in details how to:
    1. pink noise on SQ.
    2. modify EQ base on pink noise
    I need to do FOH and monitors.

    I could not find any good explanation at all.
    regards,

    Going back up to Heirloom’s post is about it.
    That said you may still not like the results and have feedback.

    Learning to identify feedback frequencies by ear and then notching that frequency with the EQ will be faster and depending on the set up you may not be able to blasting pink noise through the system very much.

    In addition to finding feed back learn to listen to the PA also for how it sounds, are the low mids too much making vocals sound muddy, do the high mids sound “quacky” is there a high frequency that is painfull like around 300ohz.

    If your looking to eq the system to flat that would be a loosing battle and flat would probably not sound good to you.
