![]() The trick is to use Saffire MixControl 3.7, but with the file 'Pro40Firmware.bin' from MixControl 3.4. Here is a driver hack to get the Pro 40 working just as well as in Win 7:įirst of all, get use the Legacy Firewire drivers. But it looks like you did it manually on your unit.After getting my Saffire Pro 40 Working without the sync problem in Windows 10 (20H2 v2) I was getting awful performance. Anyway I took it to a Focusrite authorized repair shop and the guy said he doesn't have a special soldering machine to replace this chip. So now I have these two identical faulty units and as I really need them to work I am going to buy a THIRD ONE even if I hate this idea. I could hear something getting fried and now the firewire ports on the Mac do not work anymore, neither the interface will connect to any other computer. ![]() until the firewire 400 to 800 cable disconnected from my old Mac Pro and I managed to insert the 800 port turned 180 degrees to the computer. So I got another working unit, all good, and had it happily working for a week. ![]() so I really did all I could to fix it, managed to buy a replacement PSU on eBay, paid serious money to get it delivered to Brazil (where I live) but even if the unit got to power on again it did not fix the firewire or something else which also got fried. First one got fried by an power spike in my neighborhood. I've been very unlucky lately with these Saffire Pro 40 units. since you've had the lid off and already had a decent look at the signal paths? Reply Delete I figure you have more insight on this item. So, if you've read this far and choose to humor me, my question would be if you have enough familiarity following the dac paths and if so could you narrow down my potential repair items by these symptoms or is taking off the lid not worth my time. I hate when i get started and then cant fix something. ![]() Otherwise It serves my old brain better to buy a used working unit rather than get too frustrated by a difficult repair. I'm not at all familiar with the signal path from dac to fire-wire and adat output?Īs a retired EE I would bill my time at 50.00/hr so anything over 10 hours I consider a loss unless it's fun or not too frustrating. So wo opening the lid, i think i can deduce there is a problem somewhere in the sapphire 40 chan4 dac to adat digital injection path. Channel 4 vol level indication is present on the sapphire 40 front panel leds and I can hear chan 4 in my sapphire 40 headphone monitors The Channel 4 vol level indication is present on the sapphire mixer gui when I connect via fire wire on a separate computer which i use to reconfigure the sapphire mixer hardware with preset hardware files for mixer/adat connections from focusrite online tutorials. And I also can't hear chan 4 in my rme raydat mixer or the adat return path back to my sapphire 40 10] headphone out. But Recently I noticed Its missing all channel 4 volume level indication on my rme mixer's gui software. It worked for months, great low delay ms. I'm using adat in/out to connect it with my new rme raydat pcie card and mixer software. I bought My Sapphire pro 40, the same year as yourself guitar center for $499. I fixed my 2007 Vizio TV a few years back thanks to a youtube video and a $2.00 12V power transistor, so i googled sapphire repair and found your blog and here I go again looking for a cheap way to fix my old sapphire 40. ![]()
