Even the 1375 MB/s PCIe bandwidth from Thunderbolt 2, Sonnet say is much more bandwidth than is needed.
#PRO TOOLS HDX CABLE FULL#
Sonnet explain that while this configuration does not yield the full Thunderbolt 3 performance of 2750 MB/s of PCIe bandwidth, it does provide somewhere in the region of 1600 MB/s, which they say is more than enough bandwidth for even aggressive Pro Audio workflows. The advantage to this option is that it does not require the use of an adapter.
#PRO TOOLS HDX CABLE UPGRADE#
So if you in the market for a solution with this option buy the Thunderbolt 2 Echo Express option and upgrade it with a Thunderbolt 3 upgrade card. Purchase a Thunderbolt 3 upgrade (BRD-UPGRTB3-E3) card to use with a Thunderbolt 2 version of the Echo Express III-D or III-R, which both have a PCIe Gen 2 bridge chip on the backplane board. The advantage to this configuration is that once Avid resolves the issue, the Thunderbolt 3 card can be installed back into the the III-D/ III-R TB3 Edition and the Apple TB3 - TB2 adapter will no longer be needed. Purchase (at a discount from Sonnet) the Thunderbolt 2 card (BRD-UPGRTB2-E3) card and use it with an Apple Thunderbolt 3 to Thunderbolt 2 bi-directional adapter in either a Thunderbolt 3 version of an Echo Express III-D or III-R, which will effectively downgrade it to Thunderbolt 2. In the meantime, Avid has qualified two Sonnet configurations that enable Pro Tools owners to use the Sonnet Echo Express III-R and III-D Thunderbolt chassis with HDX cards. Thunderbolt 3 Workarounds For Avid HDX Cards Rest assured that as soon as we get more information on this we will bring it to you. Sonnet have told us that Avid is aware of this and Avid are working to diagnose and fix it, but we have no information as to how long this might take. The problem when using Avid HDX cards in a multi-slot expansion chassis is the combination of a Thunderbolt 3 interface AND a PCIe 3rd generation 3 bridge chip on the backplane board with multiple slots (and this bridge chip is required to support multiple PCIe slots) means that the Avid HDX cards don’t work in these multi-slot chassis.
We reached out to Sonnet to try and understand the back story behind this statement and they told us the specific issue is that Avid HDX cards are NOT currently compatible with Thunderbolt 3 in multi-slot Thunderbolt 3 to PCIe card expansion chassis and for Pro Tools users this applies to the Sonnet Echo Express III-R and III-D as well as the Magma EBT3 chassis. “Thunderbolt 3 multi-slot chassis are not supported at this time unless using Sonnet's Echo Express III-D or III-R with a Sonnet Thunderbolt 2 Upgrade Card.”

As a general rule deviate from them at your peril.Īvid state in their Mac Pro Tools System Requirements compatibility document that… Essentially make sure you check the Avid compatibility documents before you buy any hardware or look at upgrading software. Let’s get straight to the nub of the problem. The Current Problem With Pro Tools HDX Cards and Thunderbolt 3 Following the release of Apple Thunderbolt 3 computers like the Mac Mini 2018 and the iMac Pro, we have seen some confusion about which thunderbolt expansion chassis you can use with a Thunderbolt equipped Apple computer and so we thought it would be helpful to put together a guide especially as the transition to Thunderbolt 3 has muddied the waters in this area.
