Are you saying that because of the Q (range of frequencies affected by the gain to the left and right of the target frequency) that at high gain, other frequencies are being boosted by two bands? (Hope I'm using the correct terminology here.)

From my notes, here are the values that the AutoEQ sets and adjusts:

Band 1: 25Hz, Q=1.33
Band 2: 40Hz, Q=1.33
Band 3: 63Hz, Q=1.33
Band 4: 100Hz, Q=1.33
Band 5: 160Hz, Q=1.33
Band 6: 520Hz, Q=0.83
Band 7: 800Hz, Q=0.83
Band 8: 2 KHz, Q=0.83
Band 9: 5 KHz, Q=0.83
Band 10: 12.5 KHz, Q=0.83

EDIT: It seems that one should be able to take the values given by AutoEQ and reduce them so that as few fields are given boosts as possible (ie, adjust so you are doing mostly cuts).

edit2: corrected the Q values I had.
