I have an EAD signature and it is a piece of cake to setup, that's why I bought it new years ago.. just use the remote and set the speaker size, and whether to roll off the bass or not, set the sub HZ, attach the microphone and sit back (less than 2 minutes) while it configures the volumn, delays, and polarity automatically. Save the setting and enjoy!
EAD has gone through these steps once before financially just like Wadia. But EAD is one of the few warm sounding processors.
