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.

I had a similar issue with my REL T9x. Was emitting a hum at around 60 cycles but only when using the vinyl rig. My connection is also the hi level input. I ended up replacing the wire with a set made for me by bluejeans cables. They do make a custom set that is very nice for the money. Problem went away so there may be credence to checking the cable itself. 

Cheers.
