I have read a lot of posts of guys suggesting different ways to setup your system. I am confused. Could someone with knowledge PLEASE make sense of the following: Fact or Fiction: 1. Use 'C' weighting, slow response; 2. Use meter at ear level at listening position; 3. Use meter upright when taking measurements, or 4. Angle meter towards the front and take all speaker measurements this way, or 5. Angle meter towards each speaker in turn, and take measurement; My marantz volume goes from 70 to 0db to +18db, now.. 6. Set master volume to 0db and set all speakers to read 75db on spl meter, or 7. In the receiver setup, set the level on center speaker to 0db, now turn up the master volume untill 75db is read on the spl meter, now leave the master volume and set the rest of the speakers to read 75 db on spl meter; 8. Use 75db or 85db? I can use the receiver tones, and I have Sound and Vision Setup disc; 9. I also read that you can set the master volume to -20db and then calibrate the speakers to 85db. All this info I read in different threads. I know this question has been asked a few times, but please help me!
