I do have one slight problem with it though: When I turn down the Master mixer and up PCM it sounds badly overmodulated. I can keep PCM at about 75% and turn up master, and all is fine. Would it make sense to limit the PCM mixer to about 75% of its current limits, or how does that actually work in the hardware? johannes
