I have an Ultralite Mk3. Thanks for posting this. The interface did not appear after installing the new OS; but your post eased me to a working system in minutes. Thanks! Scott

I am aware of that. The monitors work: they shut down (at about that time) when their input is fed out of a mixer (with the interface out of the chain); they do not do so when their inputs are fed from my interface - ie. it's the interface that is not operating as (I think?) it should. Shouldn't my outputs be "dead" when they are muted? Thanks, Scott

A silent period activates the 'auto-off' function of my monitors. An input of -74 dBu (minimum) activates 'auto-on.' Connected to my powered-on audio interface, with no input and the volume to Mains muted, the auto-off does not activate. (It does activate when the interface is off.) I'm using new Mogami balanced cables (balanced connections are supported by the interface and monitors). Swapping to another set of similar cables changes nothing. The auto-off does activate (as it should) when the interface is bypassed. This unit is a replacement for another that the customer service concluded was not working properly (based on a different symptom, which may or may not be related to this). With the 1st unit I had, one of two channels did activate the auto-off as expected, the other did not. (There's more: With the 1st unit, this behavior persisted with the interface shut off - although not when disconnected from power.) When I asked about this, customer service responded "Do you hear any difference in sound between left and right outputs?" This sort of stuff drives me nuts. Should I worry about any of this? Is "do you hear any difference" the sole criteria for determining whether I should ignore this issue and simply take it for granted the interface is acceptable? Thanks, Scott

Thanks. I did open the thing and get my ear right down where the video card is - can't say that seemed like the source of it. Hard to know; some hum is, I suppose, expected. It's a pretty powerful machine. There are complaints out there - but what product has none? I'll eventually get someplace that has one and listen; I'll take it on faith that if something's wrong, it'll be remedied. [An Apple store not displaying Apple's best computer? What's that all about?] I appreciate the replies. Scott

[Thanks to all the posters here, with all the wonderful information. It's really helped me.] Given its reputation for ("whisper") quiet, I am somewhat surprised at how loud my new MP is. I have a 10-day-old refurb - which I assume has been fairly thoroughly vetted. (Use: Home project studio. I don't think of my hearing as being exceptionally sensitive.) It's considerably louder than my 2008 MacBook. In fact, sitting 5 feet from the MP, with both the MB and a 2005 Dell on my lap - I only and easily hear the MP. What I hear is of the humming "refrigerator" variety of noise. I popped the extra drives out - no difference. (I did not try starting it w/o any hard drive.) I could measure this with a mic, I suppose? (I went to the nearest Apple Store to compare. They do not display the MP. Neither does the area's Guitar Center. I listened to PCs at Best Buy; a higher end Dell / Alienware. That sounded quieter - however, given the level of background noise, I could be wrong. I live a little out of the way and don't know anyone who has an MP.) Perhaps my expectation is unreasonable? I haven't worked on a desktop PC in years (and I'll grant that back then they all were loud). I'm otherwise happy with it, simply a little concerned. I don't want to start fussing over returning the computer if I'm being unreasonable or ridiculous about it. Are there any guidelines - even heuristics - I can use to start thinking rationally about this?
