I have a 861v4 without a IE12 card.

1. Can I connect DSP5200 speakers direct to the HD621 SmartLink Coax 1/2?
2. Can I still use the 861v4 analogue outputs for center & rears?
3. How would this work with room correction, or is this not possible anymore?
4. Would it be possible to connect the DSP speakers to the digital out? (Bypass)

Thank you for your replies
