One pair of jacks is simply a direct stereo patch point for channels 1 and 2. I use this as a headphone send for our drummer. I use another pair of jacks (channel 7) for the bass track that I run back into my bass amp via my active ABY box. An unbalanced transformer coupling is used here to prevent earthloops when I power the ABY box from the power supply on my pedal board. The other four pairs of jacks (channels 3 to 6) are balanced D.I.'s |

Unfortunately, the outputs of the M-audio "410" that I use with my laptop aren't balanced so I decided to make a multi D.I. for gigs. For live work with a PA, transformer coupling is really the best way to go, especially if you can afford high quality audio transformers. Of course the output jacks have to be stereo and also insulated from the metal box. There's nothing really fancy here, I just like the way I was able to squeeze 12 jacks and 5 transformers into this little box... There's really no spare room in there! |
