Carbon expansion speculation
I know that Avid won't share their "roadmap" and what they have planned for the future - that's totally understandable IMO - but it doesn't mean we can't speculate, right? What would you like to see Avid release in the future in terms of Carbon-related expansions? What do you think they're likely to release eventually?
I have zero insights or behind the scenes information - this is purely speculative on my part. The "SUR" on the front panel seems to suggest that they'll eventually make Carbon surround sound capable in terms of monitoring. No big surprise there - the clue is right in front of us. I'm sure that would be welcomed by some users. Similarly, with that second RJ45 jack on the back, I wouldn't be surprised if they eventually also allow two Carbons to be used on a single system to provide increased I/O and DSP. There has to be some sort of reason that they included that second port on the back. What do you think they have planned for it? With four headphone jacks, I kind of doubt we're going to see any sort of network expansion boxes for headphones or anything like that, but I suppose that is a possibility that might appeal to some, although I suspect only a few, Carbon users. To me, Carbon has a lot of similarities with some of the UA products. If they were not an inspiration for Carbon, I'd say that UA is definitely at least a direct competitor. I'm not interested in brand wars - I personally own a UA Octo Satellite Thunderbolt (which I really love), and I've loved and used PT for two decades (Carbon is largely replacing my old HD3 Accel rig), so IMHO there's plenty of room for both in the world. I'm not trying to stir up any controversy. But it wouldn't surprise me if Avid eventually released an AVB DSP expander for Carbon to compete with some of the UA DSP expansion options. If they offered an 8 DSP AVB expansion unit for Carbon that cost $2k or less, I'd be all over it. I don't really need more I/O than 24 (even 16 is usually sufficient 90% of the time for me lately), but I have come close to maxing out the Carbon DSP for larger tracking sessions. What kinds of expansions and add-ons would you like to see Avid release for Carbon?

Re: Carbon expansion speculation
The second Ethernet is either for future expansion or Ethernet redundancy. And it's not clear why an "expansion port" needs to be on the box--it might, but I'd sure hope that any expansion is supported between boxes connected anywhere over AVB.

In terms of your latter point, I suspect that's because AVB switches are still rare and, even if they're not, it's one less device to qualify. It took Avid a while to qualify AVB switches for the S6L and even then, I think it's only the Luminex one that is officially supported. What would make it interesting to me is a soft upgrade that allowed it to also support Dante. (Or, an AVB card for the MTRX. I'll take either.)

Re: Carbon expansion speculation
Completely agree, it's all about that monitor latency and for some folks are tight on DSP resources already and I think the add ADAT IO for more channels but run out of DSP is will cause folks issues.
Not sure about implementing Dante... has anybody looked at what is on the Carbon motherboard? (post photos ). I have no idea if there is enough general purpose compute power in Carbon to run Dante Embedded. But with so many general purpose cores in modern FPGAs it would be great if this box has CPU to spare and it's in the network path. It's a very interesting system, and the Avid AVB-Dante split-brain is kinda interesting. And AVB support on Windows and old-Macs just seems to limit adoption here. I'd have probably gone with an I/O daughter card with Thunderbolt, Dante and maybe AVB options (don't think Digilink is an option unless you want to disable DSP and have it emulater a dumb box). Stymying early adoption because of AVB compatibility just seems such a bad idea. Last edited by Darryl Ramm; 01-12-2022 at 03:32 PM. |

(UAD is the obvious competitor, but as far as I understand Apollo DSP in console mode is also limited to local I/O. The difference is their DSP plugins are useful for mixing, because they're not available natively, i.e. the hardware is a dongle.) Quote:

Re: Carbon expansion speculation
Thanks for the photo link. In this case the TI Sitara ARM Processor, a single core A-8 32-bit processor running at up to 1 GHz, has on-board dual Ethernet and that's what's driving the dual Microchip Ethernet PHYs in the photo. Sitara has hardware support for AVB, and I'm assuming the software networking stack is just fully running on that Sitara processor. With the Xilinx FPGA handling audio routing/switching. Be interesting to go poking around and find where the embedded OS console port is and see what it says is running and is doing. That SD-Card drive looks interesting, it will be the OS boot drive and other goodies. Anybody want to pop it out of their Carbon and see what is on it If it's running Linux then would be interesting to see what versions of network stuff is running to deliver AVB.
Those Sitara processors may get clocked down in many uses so would be interesting to see what frequency it's running at, not a powerhouse processor by any means but maybe able to run Dante embedded at large enough #IO here. And for your Dante wishes... hopefully it's running Linux since Audinate has Dante on Linux on ARM embedded Dante IP available. I'm going to guess the Xilinx FPGA here is mostly audio routing/switching and ancillary staff. Audinate has Dante IP-cores for Xilinx FPGAs, but unlikely that helps here. From an adoption of Carbon viewpoint and focus on the Carbon project studio market, I would guess that having Dante on Carbon is more useful than having AVB on MTRX. And also not clear that the way to do this is to have AVB and Dante out of separate ports, it might make more sense to switch the box to be an AVB box or a Dante box. May not want to support trying to use it as a AVB/Dante router, may not have the power to do that, and you may not want to make it easy for/encourage folks to mix AVB and Dante on the same physical network switches? Although I guess this is not super high number of channels/bandwidth. But dual link for redundancy or for expansion makes more sense. I'm a big fan of RME products, and was interesting to see their MADI focus open up to AVB/Milan with more than a few public shots at Audinate/Dante for being proprietary and expensive to license.... and then of course RME come out with their Dante products, but yes more structured around the edge of their core MADI and AVB systems. Oh well I'm so horribly old-school I actually like MADI, nice antique 100Mbit FDDI technology from the 1990's. Last edited by Darryl Ramm; 01-12-2022 at 05:04 PM. |

Re: Carbon expansion speculation
Out of interest which NIC are they using there. (sadly?) I understand parts of PTP, having spend time with folks developing some really amazing distributed clock technology at Stanford University that goes beyond PTP but does not need switch support (but does leverage the NIC PTP hardware timestamps), and not meant to replace PTP either, maybe more an interesting microscope to look at distributed timing and to deliver ~ns precision network time in demanding corner cases. (and unlike basic NTP and PTP stuff I sure *don't* understand Dante and AVB at any depth).

NB, support for PTP in the switch itself is optional (well, maybe not for AVB but generally speaking). It does have some advantages though, at least in larger networks, but I imagine a poor implementation is worse than no implementation.

Re: Carbon expansion speculation
PTP switch support is optional and lets be polite and say varies widely in quality, including PTP failure under congestion. It's unsafe if this is being really relied on (e.g. in financial trading) to assume it works, it's got to be tested under load. Some folks seem to assume because its an IEEE standard and the switch vendors says they support PTP that it will really work
