Very simple.
Plug in RCA cable (goes between amp and sub). Plug in power.
Plug in mic to the anti-mode, place mic on the other end to where you sit, I had it on a tripod.
Press 2 buttons to start calibrate and I left the room with all the doors shut and let it do its thing. Went to make a sandwich and a milkshake in the kitchen and when I was done so was the calibration.
The calibration at times sounded like a washing machine on a drying cycle mind. They say you should turn the gain in the sub down low. First time I did it i did it too low and I couldn't even hear the bass when calibrating so I turned it up 1 notch and did it again.
When its done it remembers it, so unplug the mic and leave everything in place. There is a bypass button you can press like it isn't there if you want to do a before and after comparison.
You can also move the mic to another position in the room and do a second calibration and the software take an average between the 2. This does 3 sweeps (main one is like 10 sweeps) of the bass notes and this is optional and it works without doing this second calibration.
And sorry no, I like it
Oh, they also say you need to do your amp's own surround sound calibration again too, I did it just in case. Didn't do any direct before and after in between the sub and the amp calibration but I do notice the following:
1 - My room feels more like a cinema now.
2 - The silences in the movie and more quiet.
3 - the bass are more "to the point", less boomy?
4 - When it is low it is lowwwwwwwwwwwwww
5 - the surround sound effects are also better? May be I didn't calibrate the amp right last time, it just feel more accurate this time.
