I have an EP350, haven't touched it yet, which is another story. Can I connect the high level input to my receiver's front B output and the low level input to the sub pre-out at the same time? I want to do this so that when I play a two channel sacd I can still send low freq. to the sub. If I have speaker B turned off for all other sources, will that affect the sub at all? I assume the high level input does not bypass the LPF. If I were to accidentally turn on speaker B AND have output from the sub pre-out, which would the sub accept primarily? I ask this because I have roommates that probably don't know exactly what they are doing.

One last question: would using the speaker B output halve the maximum power that I could send to the front L/R speakers? In other words, what is the input impedance of the high level input on the EP350?
