Hey guys, not sure what just happened. Like the title says.
While I was watching the game just now I just noticed through my Sherbourn SR-120, my sub is not putting out sound. It has been working all along and as far as I can tell, it seems like everything is still good as far as controls and menu.
When I plug the subwoofer cable in the sub or take it out for that matter, the sub gives good output but during playback or what have you, no output is coming out. I would think that if it were the cable or in the case that the sub blew a fuse the sound would not come through.....?
I just went through and tried to adjust the sub through the calibration pages and all of the speakers are sounding off but not the sub.
Any ideas on what I might be missing........Appreciate the help.

Is it possible to move the Sub onto one of the other Sherbourn SR-120's that you have?
If it works then check your connectors and settings incase something has changed on the Sr-120.
If it does not work, you can check the sub itself. Connectors , settings etc.

Thanks rocky, I am going to see if I have time tomorrow to swap cables first. Then swap for another sub. If it is the sub I can try changing the fuse.
I ran through the settings again just now but everything seems correct. Kind of wishing tomorrow wasn't Mother's Day so I could take some time to check everything....
Quick question for anyone out there....if the sub is on and it produces boom, sound or what have you when the sub cable comes in contact with the input would that rule out the sub as the problem?

I would think it would rule out a fuse and connection to the driver. Not sure about the plate amp and assiciated electronics. My guess is that it would be something outside the sub. I do think eliminating the cable as the culprit is a good idea. Have you tried powering down with the rear switch? If none of that works try another sub and if still no good, try a factory reset. |

Thanks geebo, I was just wondering about the factory default as well. I will try the steps today that you mentioned to see by process of elimination where the problem is based. Right now I think if something is amiss in the receiver set up that the signal is not being passed it will have the same effect on another sub. I appreciate the help, going to give it a try shortly.

Okay, even more confuzzled...I just swapped out subs and no sound with the second sub either...so I went back into the receiver parameters and adjusted the settings. I have been running speakers as "full" the whole time and it sounded great. I just changed them to an offset of 65hz crossover and the sub came back to life. Since these are large towers that were being complimented by the sub why should that matter?
Second, why would this happen suddenly after two years of running speakers set to "Full"?

Who did it go out with, a cute blond perhaps, maybe a redhead  And you are posting this because the sub went out with a cutie and you stayed home  Cheers Gary |

It was the red head Gary.....
Don't go getting all mixed up now, my wife is the blond and since we spent lots of time together for Mother's Day today, my sub seemed jealous, copped a tude and then it shut down on me....next thing I knew the sub was asking out our good looking red headed neighbor. My sub thinks the neighbor is really cute, and from what I heard today, they have always had a thing. They went out to dinner while my wife and I took my two girls out for Mexican. Not sure where they went out, my sub still has an attitude with me. Long story short, my neighbor and my sub seem to have hit it off. I will keep you updated!

Does the receiver have an "Enhanced Bass" setting. If fronts are set to full with Enhanced Bass on you will get a low frequency signal going to both the mains and the subs below some crossover (80Hz I think). Maybe somehow it got turned off in which case only an LFE signal would get to the sub. |

Hmm, it does have the Enhanced Bass...I will have to check that out. I cannot remember what I have the settings at now after fiddling with it but it sounds somewhat where I want it. Good enough for tonight anyways...

I made some adjustments to where the speakers and sub are crossed over and there is still no bass getting to the sub when speakers are set to Full, no matter where the crossovers are set. If I set the speakers at 70hz crossed over and the sub at 80 or what have you it makes no difference on the unit. Still no sound to the sub when speakers are set to "Full"... I checked my other two SR-120's and they are set to full and the sub crossed over at 80 and everything works correctly. Also, when I check the speaker calibration it sounds like when my surround back left is activated it is also directing sound to my center...which is really driving me nuts. Any additional info is appreciated. From geebo or anyone else! |

Direct mode is on?

1)Check and make sure DIRECT MODE is not on.
2)Unplug sub. Turn off & on several times
3) check all connections
4) does sub have a VARIABLE or FIXED switch
the better ones do. If on variable adjust setting
5) is sub in DEMO MODE
the better subs have this option

Any additional info is appreciated. From geebo or anyone else! I seem to remember with the UMC-1 that enhanced bass wasn't working right. I can't remember what it was but there was an issue. Isn't the SR-120 basically using the UMC processor electronics? But the subs work fine with fronts set to small, right? Look at this thread: emotivalounge.proboards.com/thread/28509/umc-1-enhanced-bass |

What happens when you send a test signal (for leveling the SPL) to the subwoofer?

Thanks guys. VNeal and wiskers first. Direct Mode is not on. PLIIx is selected so this should allow the split signal to both the sub and the speakers when Full is selected....I believe.
Second geebo, I just read that old thread, thank you for sharing it with me. I am going to go down and investigate further with the modes, levels and such.
Wilburthegoose, when I send test tones I am getting the rumble of the sub when selected, however there is a muted tone it seems. Not deep like it should be. Also as previously mentioned when the left back surround test tone goes through, it also triggers some sound leakage into the center....weird.
If KeithL or any Emotiva techs want to chime in I would appreciate it. Also, any other input from everyone is appreciated as well!
Also, just so everyone is on the same page. Where the speaker settings are now, everything works. The sub is fully engaged as long as it is not in the Full setting. I have the speakers crossed over where the mains and center are taking some bass on while the sub handles the rest. Just strange to me that the Full has been working all along until last week and nothing changed until I noticed the sub not producing any sound late last week.

How about another preamplifier feed from a different component going to the subwoofer. This will verify the Subwoofer is functioning as designed. Also it would tell you if there is something going on the SR-120. If you get output and it is muted, that is is suspicious.
Using another preamplifier other than the SR-120, even a Receiver, or even a fixed out device using the volume on your Subwoofer as your throttle, this could help you isolate what is causing the condition you have.

Hey vcautokid, I have already swapped in another sub with the same results so it seems like it is something in the SR-120. I think I will try powering off the SR, then I will try unplugging the unit and starting over. Who knows, maybe something will reset... |

I PM'd KeithL so I will see if he gets back with me. Otherwise I guess I will just keep it set with the speakers crossed over instead of set to Full.
