Hey folks, Jo & Rob hit a winner here for me. I can't speak highly enough of this kit and how easy it was to build and integrate in to my desk. I used 2 of these kits to build in a balanced master buss snd and rtn in my old Trident desk. Although it had one, it was unbalanced, which on my cable runs we're no problem, but given there is always a desire to make the studio 10 times bigger, I knew I wanted to run the signal over a longer wire, and all my outboard gear is balanced to, so it's just easier. The wide operating voltage of this is A1 , it allowed me to tap directy in to the main powersupply rails of the desk, no separate power supply needed for these kits. A few wiring mods later, and I have stereo balanced send and return on my master buss. Adding to that, it makes it more compatible with my range of outboard gear, as I run some newer digital stuff which can have fairly low impedence in a chain with some older analog stuff with much higher impedences and lower signal voltages. I can absolutely slam these units by using extremely high outputs from my Otari to get tape compression on the master bus, and I just can't drive these things in to any nasty sort of zone, it's almost DC to daylight :-) No noise, no ground hum, nothing!! Just my music. I can jack bantams in and out of the patch bay all day long trying to listen for any signal degradation, and I just cant!!! As with all JLM stuff, clever component orientation means you need a nice fine tipped temperature controlled iron. Try substituting some of Jo's caps with some of your fav's, I messed around with some Nichicons and some of the old blue Philips caps I had previously taken out of the desk, some nice results. In the end I used a combo of my own cap choice with some of Jo's to get a sweet result.Garron (Thu Apr 26 2012, 22:09 pm )
