I ran into the SAME thing last night....

well, just about the same thing. I have a-c's on my speakers & just bought a pair of stereo subs & a-c's to go with them. For about a week they worked perfect, then recently an audible HUM came through. last night i had a chance to troubleshoot this and when i removed the a-c's & installed a bluejeans cable lc-1 sub IC the hum disappeared 100%.

So, then i went on a tear to see what cables of mine also eliminate the hum...only an old pair of Monster cable IC's worked. However, the a-c's did WAY better than Heartland Cable IC's & every other nice IC i own.

the anti-cable shield is not that affective, but much more effective than nothing at all. I tried an anti-IC in place too, much less hum than the a-c's but nothing at all like the BJC LC-1 or the crappy Monsters.

No clue how to help you, sorry, just venting & spilling my recent findings. Now i need to decide if buy a 2nd LC-1 or look for well shielded speaker cables...i think the sound is better through sp level inputs, but i can't tolerate HUMMMMMMMMM.............

If you find an easy tweak for the a-c's to eliminate this, please let me know. Somewhere here i read about people wrapping cables in CF.

Last, i've had a-c's as speaker cables for year, NO issue with hum in this location. my subs are like antennae's though...

Actually, I also installed anti-cable RCA interconnects at the same time. Maybe it's them. - hukkfinn 06:00:20 04/04/07 (3)

Either speaker or interconnect cables can be the entry point - Al Sekela 09:38:47 04/04/07 (0)

wrapping cables in CF -- what's CF? - hukkfinn 11:57:55 04/03/07 (4)

Go about 10 threads down.... - mattcecil1@yahoo.com 14:02:16 04/03/07 (3)

Carbon fiber damps RF resonances on cables; does not cure hum. - Al Sekela 09:29:05 04/04/07 (2)

Since the problem here is RFI (radio station audible) and not hum, is CF appropriate? - hukkfinn 09:36:02 04/04/07 (1)

Don't know. - Al Sekela 16:34:10 04/05/07 (0)
