First off, I love mine, it has amazing SQ, plenty of options, and none of the popping or other issues discussed here. I have no real complaints except for the well-discussed fault of the pre-pro not holding the Logic 7-channel setting and switching seemingly at random into 5-channel mode.


Two questions: First, how does one go about revealing what firmware revision is loaded into the receiver?


Second, has Harmon released a firmware upgrade and if so, how can one upgrade their receiver?


Thanks!

I can't find any mention of 635 firmware on their website, but you could try filling out this form and see if you get a reply.

Warning, that's not a real URL, I just changed '430' to '635' in the URL for requesting the 435 upgrade. Just foolin'

Thank you for the reply. Hmm, mine says it is version 5.01. I'll try contacting Harmon and see if they have additional insight into this problem.
