I intend to use the H8000fw as 2 separate machines (DSP A and DSP B) and use them as hardware inserts in Protools. I intend on using the ADAT ports but these give me 8 in/8 out when I only want 4in/4 out. What happens to the remaining 4 in/4 out if I'm only using stereo effects for both DSP A and DSP B? Do I lose some of the effect or are they somehow muted or 'dead'?
