mourip Posted December 16, 2017 Share Posted December 16, 2017 It is an alternative audio re-sampling algorithm to the one that is built in to JRMC. If you have version 22 or later it is just a checkbox that you can try. I believe there is a standalone version of SOX with some parameter choices. I prefer it in JRMC.

Isoform Posted December 21, 2017 Share Posted December 21, 2017 RE: Mutec MC-1.2 or MC-3+ Smart Clock USB I recently acquired an Acoustic Plan Digimaster DAC which has one USB input and one BNC(SPDIF) input - both are 192/24. I play ~90% of my music from a Bryston BDP-1 digital player. I use the BNC out from the Bryston to the BNC in on the Digimaster. I have an Ayon CD-07s CD player which has only one digital out for use with an external DAC. This digital out is an RCA SPDIF. Would the Mutec MC-1.2 or MC-3+ Smart Clock USB be able to accept the Ayon RCA digital out and convert it to a USB digital out so I can use the USB in on the Digimaster? Thanks Link to comment
Miko Posted December 21, 2017 Share Posted December 21, 2017 As far s I know, the usb on the mutex only accepts incoming signals, not out going. Link to comment

There is only one USB port in the rear of the Mutec and it is an input port. Check https://www.mutec-net.com/downloads/manuals/MUTEC_MC-3plusUSB_Manual_E_screen.pdf page 13. Link to comment

You are right but the manual does not describe any mode of operation in which the device converts SPDIF (or AES/EBU) audio streams to USB audio streams. Of course data have to be sent through the USB port to comply with audio class 2.0 and for firmware upgrades, driver installation, etc. Link to comment

They would not indicate I/O USB if it wasn't.

nbpf Posted December 21, 2017 Share Posted December 21, 2017 At this point it would be nice if someone from Mutec could chime in and explain. Mutec needs anyway to make some efforts to describe the possible ways of using the MC-3+ USB more clearly. The manual that comes with the device (also downloadable from the Mutec site) is not bad but there is plenty of space for improvements and clarifications. The lights on the front panel are very bright and reading the tiny annotations between the lights nearly impossible, at least to my eyes. Link to comment
Miko Posted December 21, 2017 Share Posted December 21, 2017 I asked Julien about that a few months or more ago in this thread. The USB is only signal in...that’s that... Link to comment
Isoform Posted December 21, 2017 Share Posted December 21, 2017 I do not easily understand much of the technical side of audio electronics. It is confusing because I did study the Mutec site and it said the USB was bi-directional. It looked like I could use one of the inputs (RCA or RCA with BNC adapter) for my CD player and the USB as an out to my DAC. From the Mutec site: 1 x Cinch input (coaxial) for S/P-DIF, 75 ohms terminated, unbalanced (MC-1.3) 1 x BNC input for S/P-DIF + AES3id, 75 ohms terminated, unbalanced (MC-3+ USB) 1 x USB2.0 interface, bi-directional usable (both models) Link to comment
Miko Posted December 21, 2017 Share Posted December 21, 2017 I wanted to do something similar and was disappointed when I could not. Link to comment
Isoform Posted December 21, 2017 Share Posted December 21, 2017 I am beginning to think it is not worth it. I knew when I got the new DAC that this would be an issue. I can always use the CD player's internal DAC or my old DAC. I still want to contact Mutec directly to see what they say. Thanks all for your help. Link to comment
Miko Posted December 21, 2017 Share Posted December 21, 2017 What outputs are available on your DAC? I can try to help, tell me what you are trying to do with the equipment you have and the in/outs of each. The Mutec can accept a bunch of inputs and convert them, except to USB. Link to comment

I emailed Chris at Mutec, and he said some customers, who are using two Mutec's, are connecting the clock output, from the first one, to the clock input, of the second one, and setting the second one to EXT/RLCK. The only reason I haven't tried this configuration was the MC3+USB manual itself: "...In all cases, the converted digital audio and Word Clock signals will have the same sampling rate as the digital audio source. However, there is no phase lock between input and output signals in this mode!" In my understanding it means that even if the above config works an external master clock gen. is still needed to synchronize between the components. WIthout it there's no benefit compared to the word clock delivered in the input audio signal. With other words REF10 still rulez :-)) Link to comment

Hi all, Sorry for my absence during the holidays and a Happy New Year to you all! I agree that the manual leaves some room for clarifications. The MC-3+USB is a pretty powerful and extremely flexible device that can be used in both Hi-Fi and studio applications, so it's challenging to cover all possible scenarios without being super confusing. That's not meant as an excuse though. Anyway, the MC-3+USB is indeed a bi-directional 2-in/2-out interface. So you can re-clock a digital source like a CD player or transport and record the re-clocked audio on a computer. The interface is not full duplex though, so you can't also monitor the return from the computer through the MC-3+USB at the same time. Regarding @Isoform's earlier question: Both a USB DAC like the AcousticPlan DAC and the MC-3+USB are USB slave devices meaning that they expect a USB master (like a desktop computer or laptop) on the other. Therefor, it's unfortunately not possible to hook them up to each other via USB. Hope this clarifies most of the questions. Let me know if I've missed anything!

Best regards, Julian Thanks for the clarifications, I very much appreciated! Are there any plans for a MC-3+ USB version with external power supply? I have tested the MC-3+ USB for about one week and, while it worked perfectly and sounded fine, it did not sound better than my M2Tech hiFace Evo with Teddy Pardo 9V/2A LPSU. An MC-3+ USB with external PSU would be a natural complement to the standard version, I believe. Best, nbpf Confused 1 Link to comment
One and a half Posted January 22, 2018 Share Posted January 22, 2018 Here's an interesting perspective from Japan using an April and Mytek 192 DAC with the MC-3+USB. Compatible with the Melco (Dela) NAS designs. The author prefers natural PCM files, over the DSD conversions. One way around this is to use HQPlayer or Roon to perform the software conversion. Hey @julian.david, any chance to certify Mutec equipment as Roon Ready? Also check out the gear in the foreground & background of the photos. Right click (in Chrome) to translate to English.

Funny you should ask about Roon: we're actually in the process of becoming a partner and getting our USB devices (MC-3+USB and MC-1.2) approved for the Roon Tested program. Roon Ready is a slightly different animal that is only available when a device can be a network audio device rather than a simple USB interface. So that doesn't apply for MUTECs products. Anyway though, I expect this process to be completed soon and I'm sure you'll hear about it. Julian MUTEC GmbH Marketing Associate Email [email protected] Web www.mutec-net.com Link to comment

I guess all the 'old' MC's can have their firmware changed to add Roon in, or does it need new hardware. A networking option is pretty cool with Roon, but such an interface is not a trivial matter. Since Mutec is the clocking experts, a network to AES3/id/S/PDIF with re-clocking in the box would be a great product to have, hint, hint! Mutec hasn't ventured into AOIP and given the pitfalls, justifiably can put that on ice, with Roon though, the process is pretty much seamless with great sound quality.

Julian I am a little puzzled by this I have to say, why exactly does a USB to S/PDIF converter need to be 'Roon Tested'? My MC3+USB is happily running Roon thanks to the micoRendu that is feeding via USB, a set up that works splendidly, but I struggle to understand why a MC3+USB needs to be 'Roon Tested' any more than the amplifier and speakers that follow it. Surely it makes no difference to the USB feed if the music player is Roon, JRiver, iTunes or anything else? I have no problem with Mutec products being Roon tested, I am just genuinely curious as to what this means in practice. Can the MC3+USB be optimised in any way to suit a USB feed that just happened to originate in Roon?
