Re: passive mixer limitations?

I have been contemplating a similar project. The previous comment about gain loss is important. Even though you may have line amps to make up the gain, those same line amps are amplifing the noise floor, as well, thereby lowering your signal-to-noise figure by the same amount! Also channel independence is a problem in passive designs.
I would suggest that you reserve a passive mixer for less strenuous applications: Lose the pan pots and dedicate channels to L, R or C. Lose the master faders. Use mic preamps capable of driving 600ohms and use low impeadance T or H pads for level control. You might even get away without the x-formers. You won't have perfect balance, but I have found few problems in practice.
