REL .LFE input

I just purchased the Technics SU-G700 integrated and it has a left and right pre-out that can be used for a subwoofer - my REL. 

 

I’m currently using the high level connection but thought about trying the LFE connection as a way to reduce a very low level hum I’m getting in the subwoofer. No amount of connecting he system to one power outlet or grounding has solved it, and it only happens once the speakon connection is connected to the subwoofer. 

My only issue with this LFE solution is that there is only one single input on the subwoofer, but the pre-out is in stereo. The question is how much audio low bass information am I losing if I only run one RCA from, say,  the right channel on the integrated to the sub.

BTW, this is a dedicated two channel set up, not used for TV.

Thanks for the responses.
 

The REL only has one input so I can’t do left and right. I do not have any TV components hooked into my integrated it’s just a turntable and a streamer and all of these pieces of equipment plugged into the same outlet onto a dedicated line.

I’ll try just plugging one of the outputs from the integrated into the LFE input and see what happens if the hump persists I’m not sure where to go from there.

I did. I tried floating it and connecting it to the grounding lug on the amp.

I did check with REL, they gave me the same responses as in the video that was posted above, which I tried, and yet has not worked. I will look at the cable though and the internal wiring and such, that seems like a good place to look.

Well the wiring checked out to be good.
