Not to familiar with the Sovtek,but My Alesis mixer has direct-outs and line-outs. My direct-outs are RCA-type and the line-outs are balanced TRS-type. But let me ask you a question,are you trying to hook up your Sovtek line-out into your Tascam direct out?? If so,it'll never work. The configuration s/b Sovtek line-out to Tascam INPUT.
Which Tascam recorder do you own?
Also, direct-outs and line-outs are either TRS balanced (Tip,Ring,Sleeve) or unbalanced (Tip,Sleeve).
Don't mean to imply that you don't know what you're trying to do,just need you to clarify your question.
Peace
Mr.Q
