When I removed it from the box I was nervous and excited. I was thinking, "Can it really be that easy to get good flat bass all over my room with this rather plain unobtrusive black box?" "Did I pay to much for this thing?" I installed the supplied software and hooked the AS-EQ1 into the system. I have two SVS subs and there are two inputs on the eq for just that. After that, it goes through a series of tests and pulses in conjunction with the supplied mic. your room is quickly analyzed. It only took about a hour to do it all the first time but I did do it several times to make sure I had it right.
