The REW manual is very detailed and large. The actual method to adjust the 976 EQ will surely be in the manual but how to connect the system and take the measurements should be in the REW manuals domain. Using REW is going to give you an idea of what to adjust but it will only be applicable in one measurement position for a single persons ears. REW will provide you areas to improve in your room and may make it easier to tweak your system for perfection for your listening tastes. I am not sure REW is going to be the panacea some think it is because although easy to use it may give a user too much control and allow them to make a decent sounding system worse. Trying to duplicate and improve what most of the room correction software does will be a real task. Of course, it does give the tweakers something to do with their systems since most don't have turntables to play with any more.
