I have an 8-channel pro sound card at the moment. I was hoping to improve in the DAC department.
You don't need 2 zones. Just be selecting something like 5.1, the channels are labelled Left-Right-Center-SurroundLeft-SurroundRight-Subwoofer.
Using JRiver, I put a HighPass on the L/R channels, as my mains. I copy the L/R to SL and SR and lowPass that to create my woofer channels.
Then connecting amps to 1-2 for Mains and 5-6 for Woofers. (Channel 3 it typically used for Center, while 4 is the sub).
I use the zone function to switch between music listening, and true 5.1 movie watching with different assignments on the output channels... or to test Convolution filters.
So, my question was, can I assign a HighPass on the unbalanced channels and a LowPass on the balanced channels with JRiver and the DAC-9? Or are they linked and JRiver sees the DAC-9 as a 2-channel soundcard?
