@izjjzi Yes I did see this one, was good, but didnt make any difference...
REL Sub Hum
Hi Folks, looking to see what the issue could be. I'm hearing a substantially loud hum coming from the REL T5/I sub when connected to the Parasound A23 power amp. The other two amps have no issues... what is a power amp would cause this issue?
REL subwoofer is connecting using speakon cable... I have not tried LFE/.1 to see if the issue persists....

@blackbag20 - interestingly, hum fairly loud and constant... does not change with volume.... does that narrow down anything? |
@noromance yes, they are all in the same power outlet... |
@vinylshadow by cheaper plug, do you mean power cable? |
Thank you ALL!! I have a feeling its THIS amp (A23) and maybe it has developed any issue with grounding... my other parasound (2125 v2) with exact same configuration (ground to back amp terminal and yellow/red twisted to positive amp terminal). The A23 was working fine in the past with same RELs; I had put on the shelf for a month or two trying another amp and them plugging it in, identical as before and the issue started... which leads me to believe there is something going on in the AMP... |
