I have owned a 633 for several years and recently I've acquired a mixpre 6 as a backup recorder or to use it in small gigs. Although I like the device, I can not understand why it is not possible to access the Headphone preset list by just pressing the HP gain knob, like 6 and 7 series do. I sincerely believe that it would be a good improvement to consider in future firmware updates. Greetings, Andres

Thanks Philip, there isn,t any smell...but after 8 hours it doesn't turn on however. I'm losing my expectations

Hello everyone. I 'm afraid I've fried my SD633. I was testing a non- original external DC power supply. After connecting the mixer it worked perfectly for a few minutes, at some point I disconnected the power supply. The unit switched to batteries flawlessly. But when reconnecting the external power supply, It abruptly turned off. after that it doesn't turn on anymore. Not any LED lights up (anyone) and does not respond to power cycles and hard resets. Anyone of you ever suffered a similar problem? it is possible that the equipment has been damaged? or there is a possibility that possess some kind of protection and possibly react after a while? Thanks in advance.

I agree with Jay. Here you have more information about it. http://www.modestoradiomuseum.org/microphone man 9.html cheers
