![]() But it looks like you did it manually on your unit. 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. Please note: Focusrite Control will NOT detect 1st or 2nd Gen Scarlett Solo. 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. However when I try to use MixControl it dies abouty after 30-40 seconds and. 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. But its nice to have ya interface for DAW work exclusively anyway.Nice Project. Yes I do use a line-in and line-out sorta situation to get onboard audio through my focusrite so I can hear stuff. And it should improve over the coming weeks (for some reason - I think windows builds performance profiles or something). You may need to go down a notch or two in performance, but it'll work. And use MixControl 3.7 but with 'Pro40Firmware.bin' from MixControl 3.4. TLDR: Disable the focusrite in the 'Sounds' control panel window. You need to use an older version of the drivers, and then one file from a different version of the drivers. Introduction Thank you for purchasing Safre PRO 40, the latest Focusrite professional multi-channel Firewire interface. You DO need to use your onboard sound for every day windows stuff, but you can use your focusrite with ASIO on its own. I have gotten the Pro40 working almost flawlessly in Windows 10 latest build as of Feb 2021.
