New Echo III T5 gives new Macs three PCI-E slots across Thunderbolt 5

Sonnet's updated Thunderbolt 5 expansion lineup gives Mac mini, Mac Studio, and MacBook Pro users a way to connect up to three full-size PCIe cards with the newly updated Echo III T5.


The Echo III T5 family brings PCIe expansion to Macs that don't have internal card slots. Audio engineers, video editors, and other professionals can connect specialized hardware for recording, video capture, networking, and storage without replacing their computers.

The systems support up to three full-height, full-length single-width PCIe cards, or one double-width card alongside a single-width card. They're compatible with computers equipped with Thunderbolt 5, Thunderbolt 4, or USB4 ports, although available bandwidth depends on the connection.

Each system uses one x16 and two x8 PCIe 3.1 slots. The systems support compatible non-GPU cards and are qualified by Avid for use with up to three Pro Tools HDX cards.
