Uttt...ohhhh

ODD. Maybe TLS has a thought, seems like the outlet or the splitter would be the culprit. Is the splitter connection secure and not in contact with the avr chassis?

The splitter had this huge barrel on it and touched the other housing of some cables. I wrapped it with a electrical tape. That may be the issue...huh...?

Ive had it happen before

I hate ground loops.

I think Scott has it with that splitter touching something. Either that or when you slid out the rack it pinched/moved/cut something that is now causing this. Now you are going to have to upgrade your AVR to one with 2 sub-outputs.

 

[GlocksRock]

Or instead of splitting the sub out from the avr, use the output from the amp on the ultra, or switch to XLR cables.

 

[ParadigmDawg]

Not the sub splitter, not the outlet, don't see anything weird with any cables...crap, crap, crap...

 

[Warpdrv]

for now, try a 3 prong to 2 prong adapter and see if that fixes things temporarily... it will by you some time until you narrow down that ground issue....

thats to easy, he needs to check all the electrical runs

 

[Warpdrv]

Jesus, have some heart....
At least he can have a moment to enjoy the sub.... for crying out loud..

 

[ParadigmDawg]

On the sub?

It even hums when the sub is unplugged.

You could always try the ground loop isolators mentioned in this article.

My friend got one and it fixed his ground loop problem.

Where would I put that? I have nothing with coaxial cable.

You don't have cable or satellite tv? My buddy had a bad ground loop hum when he added an EP2500 for his kappa build, no hum existed before he added this amp, and it didn't matter what was plugged in where, the ground loop was always there until he added the isolator, then it went away. It doesn't make much sense to me how the coax cable affected the amp that was plugged in to a complete different outlet, but adding the isolator was the only way to fix the issue. You can just unplug your coax from the wall and if the hum goes away, you know you need the isolator... if the hum is still there after unplugging the coax then you don't need the isolator as your problem lies elsewhere.

 

[GO-NAD!]

Getting closer, the BJC sub cables came in. Sub is scheduled to arrive between 2 and 6pm on Friday.

I see now, that my wall plate is not square. I guess that's what I get for cutting the hole without moving the credenza out of the way. Oh well, you can't see it anyway.

Well, I'm disgusted!! If you can't even install a wall plate correctly, you have no business picking up a hand tool!!









J/K!! If it wasn't beside another plate, it wouldn't be noticeable

 

[Warpdrv]

So this started when you put the RCA splitter and the new sub cable and it wasn't there before...?

Where did you get the wall plate... Can you remove that and see if the hum is still there....?

 

[AVRat]

What is the splitter you're using? I tried the BJC splitter when I purchased my duals and it had the hum. Fortunately, I had ordered the Y-cable at the same time and the hum disappeared.

 

[Warpdrv]

If you don't get better results with a different Y cable, my thoughts are that the long RCA cable up and over the top is picking up noise from electrical along the run.

It may come down to you needing to replace that RCA and run a Balanced XLR cable.

I would also try if you can, instead of using the splitter, just run one cable to the close sub and run the long cable out of the Low Level Out from the first Ultra to the other sub... daisy chain style, if its at all possible.... worth a try

Oh goodness, I didn't see that....heheheh
