Sub Settings on Sony STR-DE835 (1 Viewer)

[Brandon_S]

On my Sony receiver, there are two settings that deal with the LFE. LFE mix and a subwoofeer setting. Currently I have my LFE mix set to -10 and my subwoofer setting is set to +5. Do these sound right? Configuring sound has always confused me. I am using a Sony 12 inch sub as well. Thanks for your help.

It's my understanding that the LFE mix deals with both the LFE channel and any bass being redirected to you sub via setting your other speakers to small. The subwoofer setting only adjusts the LFE channel. I would suggest setting the LFE mix to 0 and the subwoofer setting below 0 as prescribed by others in the forum. Here is a link to a post of Vince Maskeeper's,Link Removed , I'd suggest setting your sub's separate amp level as high as it will go than setting the subwoofer setting to -10. Then using Avia or Video Essentials, calibrate your sub to your speakers using the receivers subwoofer setting to lower or raise the sub's volume. Anybody please feel free to chime in and correct me if I'm wrong.

You normally want to keep the LFE setting at it's default, and only adjust the Subwoofer setting on the receiver. What are you using for measuring your settings? Are you using the Avia or Video Essentials DVD, or just the built in tone generator on the receiver?
It is suggested that you set the volume knob on your subwoofer to about 3/4 up, then adjust the volume of the sub from the receiver's sub volume control. You'll need a Radio Shack SPL meter (about $35.00 for the analog version) to measure your tones. Using either the Avia or Video essentials DVDs, you can calibrate the volume on all your speakers, including the subwoofer. A note here on the Video Essentials DVD, even though it says the tone is LFE(not subwoofer), you should be adjusting the subwoofer volume setting on your receiver, not the LFE volume setting.
I hope this helps...

Thanks for the great info guys. I have actually yet to purchase Avia and a SPL meter. I'm sure they are well worth the investment...I just have to stop spending so much on the damn DVDs themselves . Thanks again!
