Don There are some real high dollar sound cards that are really and truly balanced, but they cost as much as the SDR-1K. We use them extensively at work since all our spots (commercials) all the drops (cute sound effects the jocks and talk hosts play) and most of the music we play are on hard drive.
The board that the jocks operate is just a work surface for another computer, and they are surrounded by touch screens to control the afore mentioned servers. Unless you've got a lot of spare cash the Delta 44 will do "jest fine". It really is a good sound card from the software and computer hardware point of view, and the Flex Radio guys scored big time by making the decision to standardize on it. There's a whole lot of between the ear processor time being expended by those guys. Thanks Folks!!! What Delta is doing is fairly common of low end "professional gear". Behringer does the same thing on their low dollar mixers as does Soundcraft, Yamaha, and others. Mackie uses real balanced line ins and outs on their mixers with the exception of the stereo line inputs, and the aux. ins and outs which use the pseudo balancing like you're seeing on the Delta breakout box. I posted a PDF of just what you're contemplating a couple of months ago. I did it to clean up some of the cable kludge behind the computer, and to eliminate all the ground loops that I can. We won't be able to get rid of all of them because of the data cable and the unbalanced ins and outs on the radio, but it's a start. I did get some feedback from one list member who has used my drawing with success. He noted that it eliminated (or at least reduced drastically) most of his ground loop induced noise and allowed him to ground his computer which he had to ground lift because of noise issues. 73's Bill AD5OL >>> "Don Newberry" <[EMAIL PROTECTED]> 08/04/05 10:25PM >>> Hello all, I was considering using a DB 15 connector, appropriate plugs and shielded cable to interface between the SDR and the Delta 44, bypassing the breakout box altogether. I thought this would make a little cleaner setup here (not that this has mattered much before, hi). I traced out the wiring inside the box to find out the pinouts for the various ins and outs, and will list them below. Don, wd4egf
