Thanks for your quick response.
My preamp actually has XLR balanced outputs but I have a 2 channel line level converter to allow me to switch to RCA unbalanced lines.
I'm not in the market for another mixer yet, but do you know if any of their later models use XLR line inputs, not just MIC inputs?
Another question. Do you know when Tascam switched to using Pin 2 hot on their XLR connections, instead of pin 3 hot on their earlier equipment?
