Thank you both, The Audiogon thread does indeed apply. And it is exactly what I suspected. I want to use a discontinued Dynaudio sub with the Transporter whose balanced outputs go to the powered dynaudio BM5a's.
The Transporter's RCA's go to a whole house audio system. I'm not sure if the RCA's were dedicated to the sub, bridged and run to the sub the volume adjustment would track together with the XLR outs anyway. The sub has a lowpass filter-so I don't need or want a crossover. The only option that I can think of is to use the sub for only the very lowest frequencies and assume they are equally recorded on both channels. If that is a good asumption then I could run just one channel to the sub using a balanced "Y" connector. I suspect this is why the amp is discontinued. Modern Dyna subs accept both L & R and combine them internally after some sort of buffer stage so the whole system doesn't become mono. What do you think of the one channel only to sub idea?
