No frequencies get boosted, all frequencies are cut to match a target curve. We placed the target curve (drag and drop) onto the freq/amplitude chart of the measured room response so that all freq plots are above the target curve. Then Tact adjusts all volumes downward by some amount to result in the target curve. The weird thing is that it seemed like the corrected sound was much louder (2dB?)than the bypass mode with no correction. The dealer explained that when all the freqs are clearly audible after correction, it seems louder, and indeed at the point of correction (microphone location) it is louder because SPL reducing negative nodes are removed, but total energy in the room is not changed and same power is coming out of the amp, just optimized in EQ to match room thus much more efficient use of power and higher level. It seemed louder no matter where we stood in the large room because the long wavelength bass tones were corrected too. Comparing the sonic character of corrected and bypass requires boosting gain of bypass mode to match the corrected.
