I'm considering an Ultracurve Pro 8024 for equalizing my 2 subwoofers. I have an amazing room resonance that needs to be tamed if I'm to get good LF response. I ONLY want the 8024 for the subwoofers. So it would be 990 subwoofer out => 8024 => subwoofers. The problem is that the 8024 is a prosound device that needs +21 dBu (~8.7V) for digital full scale. Consumer analog output is more like 1V. Can I just manually adjust the woofer output to +15 dB (max), and crank it back down on the subwoofers? I have a good sound measuring system to monitor the adjustments.

Any insights appreciate.
