[QUOTE="Geoff Doane, post: 49362, member: 1155"] Re: Line Level Isolation Transformers That's one of the advantages of using the plastic chassis connectors. Even if an XLR has the shell connected, it won't go anywhere on the box, unless it touches something else inadvertently. The current scheme is essentially ground lifted with an RF bypass (like Jensen's recommendation) but there is no option to connect the ground. As I said in the first post, I'd like to avoid switches if possible. I made some similar boxes a few years ago that had two input XLRs for each channel. One had the ground connected and the other was lifted with an RF bypass. It takes more real estate that way, but the cost of the plastic XLR is about the same as a toggle switch. GTD [/QUOTE]
