indispensable in the well equipped home studio
If you have a mid sized mixing desk with unbalanced inputs in a building without a dedicated audio ground scheme (a home studio) you need some way to eliminate ground loops and interface balanced only processors with unbalanced mixer connections and patchbays. This is the lowest cost alternative and performs every bit as well as the slightly more costly proco version. I have a number of these. You don't always need them for interfacing balanced gear but they really simplify your life when there's a ground loop coming from one specific piece of gear (my main culrpits are my valley pieces like my dynamites). This guy will knock that right out. Its very transparent.... the transformers are 1:1 and pass 10hz-50khz, more than enough bandwidth. its pretty darn flat but as with most transformers it actually semms to add a subtle bump to the lows that will flatter any bassy source. You really don't need to go with a radial or jensen unit that will break the bank when the ART T8 does the job for a fraction of the cost. It has various connectors to each transformer and the rack ears are reversible so you can keep everything nice and tidy. I can't recommend the T8 highly enough for your home studio patchbay.

Great writeup, as usual. How long do these things live? How old is your oldest surviving T8?

@pkennethk unsure, they're all used... I have 4 and the first one I bought was 15 or so years ago when I wanted to rackmount iso/matching transformers in my mobile recording rig instead of using the little 2 channel DI sized box I had originally. They're passive and the transformers don't see any strain so the life is as good as the jack life and PCB trace durability.... there's nothing inside the but if you went to build a unit like this it would be a nightmare to make it rackmountable and would add up fast in cost. I added this review because I just bought a 4thone, I can usually score these for $100 or less...

@pkennethk I wanted some more channels because of how much gear I got on the cheap lately, no issues yet but I'm also thinking of changing mixing desks so who knows what I'll be up against trading up!

@jimmarchi1 if your oldest is at least 15 years and still kicking, that's good enough for me. thanks!
