    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.
