What exactly is the output of the toslink? Does it have to be the same as the L/R channels, or is it programmable? Does the DSP volume control change the toslink output? Curious if a high pass filter can be added to the analog outputs and then a low pass digital signal to a subwoofer amp. Thanks.

  As the DSP is fully programmable, you can map whatever you like. We provide pre-configured DSP programs that might not fit your needs. If this is the case, you can use SigmaStudio to create your own DSP flows.

  Just note that SigmaStudio has a steep learning curve and there is no support from us for user profiles.

  That's what I was hoping. Didn't want to start climbing that curve to find out it isn't possible. Thanks!
