I calibrated Dirac Live within an Arcam AVR 20 AV Receiver into a KEF 5.1 system with a REL Q200 Subwoofer.
I start every calibration by checking over a few basic things and I noticed something was a little strange with the system, the customer had rewired it recently and had made a mistake with the speaker cable links, easy done. He has done an excellent job placing his subwoofer and setting a good level for his average listening level and to not upset his wife.
I worked with the customer through the measurement process, then spent time maximising the systems sound for music, followed by movies, probably testing the system a little louder than the customer would normally 🙂
I ended up setting him 2 variations of the calibration, one for day and one for night with reduced bass and more centre speaker presence.
