lenticularis Posted July 25, 2020 Share Posted July 25, 2020 (edited) Item: Price Range: $250-350 Item Condition: Used Extra Info: This is a discontinued item in Mutec's range, however it does SPDIF to USB conversion which is what I'm after. Please don't forget to report your post as FOUND when possible. (You can now delete this text). Edited July 25, 2020 by lenticularis Link to comment Share on other sites More sharing options...
Ittaku Posted July 25, 2020 Share Posted July 25, 2020 By the way, you will see this device only has a USB B connector. That means it doesn't have USB out in the way that would interface to a DAC (either.) I don't believe there's such a thing as a USB B male to USB B male converter unfortunately.

"1 x USB2.0 interface, bi-directional usable" And the connection looks common like seen on printers. Or am I misunderstanding your point being made?

Or am I misunderstanding your point being made? Yes you are misunderstanding. You can't have a "printer end" at both ends of the USB cable, meaning you can't use USB out on this device to plug in to a DAC. You can only use USB out on this device as a USB input (recording) device on a PC. Edited July 25, 2020 by Ittaku Link to comment Share on other sites More sharing options...
sakabatou Posted July 25, 2020 Share Posted July 25, 2020 I think I've seen this discussed elsewhere. That interface allows you to input spdif via usb into your computer, (which is a usb host), rather than a dac. I haven't looked at the specs or documentation, though Link to comment Share on other sites More sharing options...

You can connect PC USB -> Mutec -> SPDIF on DAC You can connect DAC/PC SPDIF -> Mutec -> USB on PC You can't connect DAC/PC SPDIF -> Mutec -> USB on DAC Does that make it clearer?

Yes Pity they don't make it clearer in their site! Guess it is a no go for someone with a USB only DAC then Link to comment Share on other sites More sharing options...

You could put a raspberry pi after this and then use it to capture and then send it USB out again but that's very convoluted and not exactly a trivial task for most people. I've done it but it's messy. 1 Link to comment Share on other sites More sharing options...

That would make sense. I wonder... Is it a physical cable form-factor issue, or a USB protocol issue? I too was noting the advertising blurb from the quote on the Mutec-1.2 advert. I have a USB Type-A to Type-B adapter, so I do have the ability to fashion a Type-B cable at each end, if form-factor is the limitation. It's a pretty expensive error to make if the assumption proves wrong of course. Link to comment Share on other sites More sharing options...

About the only safe part, I guess, is that power can only be pushed down the type A connector so if you do B to B you shouldn't blow anything up (hopefully). 1 Link to comment Share on other sites More sharing options...
muon* Posted July 26, 2020 Share Posted July 26, 2020 Type B at both ends are available to buy at a few places. If not powered via USB you need to use a power supply. Only sure bet is to email them and ask. 1 Link to comment Share on other sites More sharing options...
