New R-112SW won't auto power on

I just got my new R-112SW this week and love the sound, but it won't auto power on.  I have a new Sony STR-DN1050 running the show.  I have the sub hooked up to the LFE port and I have tried multiple sound fields that are putting out a signal to the sub.  Any help would be great.  I have just been leaving the sub on for now.

Might be a setting in the Sony. Or, the rocker switch on the sub might not be set to auto. Have you tried turning up the sub trim on the receiver? Not familiar with Sony receivers, but if it's a HT receiver it should have a separate sub trim.

Oh, and welcome to the forum.

If it's new, you need to go into your receivers bass management area, set your speakers to small and be sure you select yes for having a subwoofer.  Your sub most likely isn't getting  signal and with no signal, there's no auto on.

So this is a 7.2 receiver. I'm not sure I'm understanding the problem. You get lfe when you just leave the sub on, which would tell me the receiver has sub out on. Per CECAA suggestion, all speakers to small. Is this your current setting? Sub out to yes. Run D.C.A.C, and then raise the sub trim through the receiver. Out of sheer curiosity, where do you have the volume on the sub itself set?

Thank you for all of the input.  With all of your help I did solve the auto on issue.  After digging in to the setting for the sub.  I found that after the auto calibration the sub output was at -10 db.  Which wasn't enough to wake up the sub.  My settings are the usually THX type settings.  Size and crossover settings.  I will need to tweak the system and re-calibrate it, but now I know why it the sub would stay off.  I did try and calibrate the sub both the "Sony" way and the "Klipsch" way noted in their owners manual and neither are perfect.  I'll need to work on a happy medium.  Sony's setup is turn the gain and cut off to the max level on both and let the system adjust as needed.  That's where the -10 db came from.  Klipsch says to let the system handle most of the setting making sure the crossover settings in the A/V unit are set to the normal crossover settings and adjusting the gain in the A/V unit to match the speaker levels.  Do any of you guys out there have a better way to perform a good calibration?  I'm currently running my original R-3 speakers from 1999.  RF-3, RC-3, and RS-3's.  They have been good to me, but I have ordered a full set of the new RP speakers. RP-280F's, RP-450C, and RP-250s's.  It will be a 7.2 setup with 2 of the R-112SW's.  I went with 2 12's vs the 1 15 inch sub. I always run 2 subs in my setups.  So with that any input from you guys would be great.  Thanks again.

Why not just leave the sub always on and not use the auto-on feature.  I did this for years and it really does not run up the electric bill.  Also, using a Y-adapter rca connector to go in the white and red sub inputs on the sub will increase the signal to the sub and help with the auto-on feature if you want to use it.

 

I did not like the sub clicking on and off with action movies, just me.

That is good to hear that things are working.  The Y adaptor is not used at the avr end, it is used at the subs. 

 

Using a Y adapter on most, but not all, subwoofers will increase the sound level from 3 to 6 db.

Aperion Audio Subwoofer Y Cable
"Why, oh why do you need a subwoofer Y cable? Most AV receivers come with a single sub output while most powered subwoofers come equipped with left & right inputs. By using a subwoofer Y cable for both the left and right subwoofer input, you can increase the bass output of your subwoofer by about 3dB."  http://forum.blu-ray.com/showthread.php?t=95817
