    Before I start calibration, I have my Yamaha 595A set up like this: all speakers set to small, bass set to SW, SW level at -15 (range is -20 to 0), all other speakers levels set to 0, DD LFE set to 0 (range -10 to 0), DTS LFE set to +10 (range 0 to +10). I have a friend coming over with an SPL meter and I have the AVIA disc.

    Do I need to use the meter and set the speaker levels on the receiver to 85hz? Any help is appreciated. Thanks

    Rikk,

    You got it. There are some additional tips in the FAQ and PRIMER (link in my sig).

    Bill, when I am adjusting the speaker levels, is that done in the receiver settings for main, center, surround and sub? Currently the speaker levels are at 0 and the sub level is -15. Thanks

    Rikk, sorry for the delay...

    not quite sure I get the question...Sub level is a good start BTW so long as Sub gain control ends up in the 1/4 to 3/4 range on the SVS dial.

    Speaker level settings are adjusted using Yamaha's scales via the remote: It doesnt matter where the Ctr and Surrounds numbers end up on the -10 to +10 scale because that depends on your spkrs and the room.

    On my Yamaha, once I've set the LM to 85dB, for the RM I must use the Balance control feature found in the remote set-up.

    Sub calibration follows logically.

    Bill, I guess I am just not sure what to be adjusting with the SPL meter. The settings in the Yamaha are 0 except for the sub, when I get the meter what do I do first? Thanks

    well, rik, this is standard Avia calibration. RS meter is set up (I use a camera tripod) in the main chair seat, tuned to 80 scale C Weight/Slow.

    Avia Audio Chaper is dialed in to LeftMain tone, then Yamaha Main Vol control is raised til you see 85 reading on the meter. Make a note of what numvber the Yamaha Master Volume ends at. Like I say, this is YOUR reference level. Chances are you will NOT play this loud on later DVDs.

    Leaving this Main Volume level, switch the Avia to the Right Main, then Center Channel then Surrounds, changing the Ctr and Surrounds from "0" where you have it, to where ever it takes to read 85dB again on the meter.

    Is this what you are asking?
