I am going crazy trying to work out my home DJ setup. I have the following components. Technics 1210 turntable (RCA) Integrated hi-fi amp (RCA) Native Instruments Audio Kontrol USB soundcard (Balanced) Channel Islands Audio Phono pre + dedicated power supply (RCA) Aego M 2.1 speakers (RCA ) My soundcard has 1/4" balanced ins and outs. However, I played my first digital set recently and it was a disaster. The sound on the floor was muffled and quiet with audio drop-outs (not to mention no monitor headphone output). RCAs on the mixer were used. I'm guessing their was a mismatch and the soundcard didn't have enough juice. I want to do the following: 1. Archive all my vinyl for digital use 2. Use my soundcard with the Aego M system for general computer audio 3. Avoid the same problem with DJ mixers if I ever get booked again I understand that I need a DI Box. Ideally, I would like one box but that may not be possible. Their is something called a Matchbox HD that is bidirectional or I could get something like a Radial J33 (phono pre-amp and DI box) or a stereo DI Box and connect it to my home hi-fi amp then into the soundcard. The last two solutions will require another box to use when I play out, though whereas the Matchbox could be used for everything. Am I right in my thinking? It all seems so complicated. Any advice greatly appreciated.
