For the .1 channel, the low-passed signal will be at 100% even with the volume down low if you use the Tape loops.
Using Pre-out / Main-in with External Crossover
I was thinking about using the pre-out & main-ins of an integrated amp with either an external analog crossover or mini-dsp for the purpose of 2.1 bass management. My question is, will this loop degrade my sound any more than wedging a crossover between a separate preamp & power amp will?
