@holmz I was able to try your original suggestion. I was on Emotiva’s website to buy a 12V trigger and they had XLR to RCA adapters, so I bought 2 of them. I hooked up a pair of 20’ balanced XLR cables to my preamp, added the adapter just before my amps and connected a short run of RCA cables between the adapter and the monoblocks. Success. No hum, no feedback, just a silent connection. Sounds petty good, too, when playing music.
Thanks, all, for the help
Glad that worked out.
At least if it didn’t work out, then you would have had the cables needed for the Jensen isolators.
I have a bit of hum seen on a measurement spectrum from the TT, but when I play back file at +12dB I barely hear it with my head against the speaker.
So if it sounds good, then as they say say here, “You’re Larfin.”
Hopefully the next fellow or lady doing a search will find your thread helpful.
Thanks for putting a bow on it.
