AGREED, one end and one end only, or youre asking for a ground loop....ground the end with the best, shortest path to earth ground.....in his case, that would prob be the telco room end, "usually" theres a decent ground there somewhere..... Mileage may differ...
Some hours reading the back issues of the journal found at http://www.compliance-club.com will hopefully inform you why star grounding is a thing of the past. Ground both ends. If you are afraid of ground loops, place a heavy (as in 10-16mm2 or AWG way below 10) ground conductor alongside the signal cable, and ground it firmly in both ends. That will take the current away from the shields. Ungrounded shileds are inefficient for EMI and RF shielding, while at times efficient AC hum blockers. And, IANAEE, but I've played with big sound systems that exhibit all these problems. - -- Måns Nilsson Systems Specialist +46 70 681 7204 KTHNOC MN1334-RIPE We're sysadmins.
