Hum from REL sub?
I own an older REL Stadium III sub that I have paired with my new Cremona M's. While I feel the REL is a very musical sub and I was able to integrate the sub easily and correctly with the Cremona's...I have a persistent hum coming from the REL using the included high level Neutrik cable.
Sumiko has informed me that because my power amp is balanced (it is a Blue Circle BC206) that I have to connect the black wire on the cable to a chassis ground on the amp as opposed to the negative speaker terminal as instructed in the manual. I have tried Sumiko's suggestion but I am still getting a hum. It is very frustrating because I really want to keep this sub. I have no other ground loop issues. The REL subs seem very sensitive to ground loop hum when using their Neutrik high level cable As anyone else experienced a hum with their REL sub? Any suggestions on how to eliminate it? |

I have my negative connected to a ground terminal on my power conditioner. This was advise from Sumiko. Worth a try.

Thanks for the suggestion. Unfortunately, it is impossible for me to get a ground connection on my power conditioner. Sumiko has also suggested I try and ground it to the earth ground on my dedicated power line but that is 6ft away from my amp. I am going to cut the outer jacket on the cable and give that a try.

I had the same problem so I crimped on some extra wire to be able to reach. The support from the distributor was excellent.

I love my G1 and would not trade it for anything!

There is still a slight transformer hum but I can live with it. Now I need to find myself a second REL Stadium III. |
