Sub(s) Calibration (1 Viewer)

[Chris Ryan]

Hi:
I have a question regarding sub calibration? I am using a Denon 5800 & have Def Tech. BP2000's and a Infinity Intermezzo 1.2s for subs. How exactly should I have the sub volumes on the subs when trying to calibrate? Half, quarter, etc? Right now the volumes on each sub are way down. On the Denon, the peak level limiter is set to -13 db. Should I even use this? The sub level is set to +5 DB's. I just don't think I am getting all I could be from them. Also, when I use my level meter & VE for sub calibration, the needle never swings. It's always at the far right.
PS. I want the Infinity to do most of the work & my mains are set to Large the rest are small and I am using LFE+Main.
Thanks,
Chris

Chris,
The gain on the sub should be turned all the way up...at least to 75%.
I, too, have a Denon 5800 with SVS for a sub. My gain is at about 90% (on the sub) and my receiver level is at -12db.
Make sure your SPL meter is on C weighting, and calibrate it a couple of dbs over your mains...then adjust it to your taste.
It's better to have the gain turned up on the sub amp and your receiver turned down (ch adjustment)....less distortion this way and easier to get a handle on where the dbs of the sub are.
If you have any questions, feel free to e-mail me and I can walk you through it.

Thanks a lot!
Do you use the peak level limiter? Should I leave it off? My speakers are calibrated at -10 db for volume.
