[BC] Moseley AES issue

[Bob Tarsio]

It is apparent from Ed's comments that this problem is a bit more widespread than I thought. I will reiterate what I posted earlier in that we have encountered this problem before and have helped customers solve this problem with the addition of our ATB Audio Toolbox series products. If you need to switch and route anyway, our products can be a good solution to this problem. Of course you can try and get the other manufacturers to figure out a fix for you but as Ed has attested to this can be a long and arduous process.
Another common problem that we encounter is the use of non synchronous AES switching causing AES receivers down the line to lock up. Some equipment cannot tolerate a non synchronous interruption of AES clock and it causes them to lock up. Some will recover after several seconds and some others require a reboot. Again, we have solved this problem with our ATB series product by doing all of the switching synchronously. I encourage those with questions about this to contact us about our product solutions or to visit our website. We recognize that AES audio delivery is not a trivial matter and try to work closely with customers to produce solutions.

As recently as 2007, and despite input from myself, Harris and BE, Moseley AES outputs continue to provide a CONSUMER, rather than PRO flag. Many professional boxes downstream will ignore improperly flagged data, and in some cases provide improper de-emph as well without the 'pro' bit.
You can check for this fairly easily by using a Bit Buddy. Check the AES source going into the Mosely transmitter, note all the diagnositc and error lights. Then check the AES coming out of the Mosely receiver. If the lights are not identical, you probably need the field modification that Kevin at Mosely assured me in 2005 did not exist.
Contact Moseley and ask for the bulletin on this. The bulletin exists because both BE and Harris worked with them on it. Yes I am being pissy because Moseley has refused to be proactive with this necessary correction and wont make the effort to notify and correct this oversight. I think Toyota learned QC from these guys.
It is just inexcusably bad design and then the horrid, rude, unaccountable attitude and waste of my time at a real $$ loss that I encountered when I first documented the problem in Dec. 2005. How is it four years later this is still a problem for Moseley users.
