The manual for your Denon receiver shows you connect ONE RCA cable from the PRE-OUT Subwoofer jack to ONE subwoofer. Do NOT connect BOTH PRE-OUT Subwoofer jacks to BOTH jacks on one subwoofer.

Thank you Peter! 
 

I bought the speakers used, they aren’t even a year old but unfortunately he didn’t have the manual on hand but have looked it up online.

 

I now have one cable on the pre out on the receiver, with both the red and white end of the cable connected to the sub woofer now.

hot/neu rev when pressing the test button. 
when I don’t press the button and hold the button it shows open ground so it only confirms most of my upstairs isn’t grounded. How much does this typically run to get it grounded? 

 

lastly the bathroom, kitchen and basement showed up as correct. I eventually will be moving these speakers into the basement. 

From this youtube vid it looks like I can just replace the outlets to have it grounded?

Definitely agreed! I get the outlet tool today to check to see if they’re wired correctly which I’ll be doing first before hooking it back up

Maybe it was even just static shock? It definitely took me off guard but didn’t do it every time. 
 

The receiver I have is the Denon AVR S750H, I don’t see an LFE input, it just has Sub 1 and 2. 
so I bought a Y cable so one end goes in sub 1 and then the red/white end to the subwoofer. Would that be correct? 

Thank you for the information again, this is my first surround sound set so I’m a little new to this and was luckily able to get this in my opinion for a steal.

Hello Peter,

 

Thank you I went ahead and ordered one to check just in case. I know on my surge protector it says that it is not grounded so I’m not for sure if that’s the issue or not. Should I be plugging in the subwoofer directly into the wall outlet instead of through the surge protector? 
 

Also one thing I noticed I did was have the red and white RCA cables in both subwoofer slots on the receiver, maybe it was overpowering the subwoofer?

 

The RCA cable I was given is a dual RCA cable but it looks like that would be incorrect? I ordered a Y RCA cable instead now as well after watching some videos.

Hi,

 

Greetings!

 

I have been using the R12SW subwoofer for almost 3 years now, and hands down I am always in love with it!

 

I recently shifted homes, and the entire audio setup was uninstalled and reinstalled completely by me. Can’t just let anyone else touch it.

 

However after installation, when I touched the on-auto-off switch behind the subwoofer, I got a pleasant electric shock. Unfortunately I don’t have a voltmeter, and using an electric tester I found power at every metallic part of the subwoofer (be it screws, switches, line in ports).

 

(PS : range of electric tested is 110-240v)

 

I disconnected the RCA cables, changed the power source : but all this did not solve the problem.

 

Can you please advise what can I do next? Do you feel there is a loose connection inside the chassis, or a foreign object there which is causing this power leakage? 

Due to these pandemic times taking it to a service center is not an option.

 

Thank you so very much for your suggestions!

Best regards

Anamitra

 

Hello,

I recently bought this set as well from someone and mine is doing the exact same thing! Did you find out the issue?

 

I was going to call an electrician out to take a look at my outlets as my home was built in 64.
