Sonnet Echo II DV T5 Desktop connects two full‑length, single‑width PCIe cards to computers with Thunderbolt or USB4 ports.
Each PCIe slot is paired with a dual‑port Thunderbolt 5 interface so two high‑bandwidth cards can run at full performance simultaneously on appropriately equipped hosts.
The unit includes a universal 400W power supply, dual 75W auxiliary PCIe power connectors, dual Noctua fans rated at 17 dBA, two Thunderbolt 5 cables and three ThunderLok connector locks.

The Sonnet Echo II DV T5 Desktop is a two‑slot Thunderbolt 5 to PCIe card expansion system designed to add professional I/O and processing capabilities to laptops and mini desktops that lack internal PCIe slots.
Each PCIe slot is paired with its own Thunderbolt 5 interface so two high‑bandwidth cards can run at full performance simultaneously when the host computer supplies independent Thunderbolt PCIe lanes.
Echo II DV T5 Desktop features two x16 PCIe 4.0 slots that support Thunderbolt‑compatible, single‑width, non‑GPU PCIe 4.0, 3.1, 2.0, and 1.1 cards including video capture, streaming and transcoding cards; SSD storage; audio DSP; and multi‑port 10Gb and 25Gb Ethernet cards.
The unit contains two dual‑port Thunderbolt 5 interfaces (four Thunderbolt 5 ports total), with one interface dedicated to each PCIe slot; each interface includes two Thunderbolt ports to enable daisy‑chaining and single‑cable connection options.
When connected to two Thunderbolt 5 computer ports that provide independent PCIe lanes, each installed card can receive 6800 MB/s of PCIe bandwidth; with Thunderbolt 4, 3, or USB4 hosts the available bandwidth is 2880 MB/s per card.
Echo II DV T5 integrates a universal 400W power supply and provides two 75W auxiliary PCIe power connectors (one for each card slot) for power‑hungry cards; the secondary Thunderbolt ports provide 15 watts to bus‑powered peripherals.
Cooling is handled by dual Noctua fans rated at 17 dBA, with temperature‑controlled operation to balance airflow and noise for use in recording and broadcast studio environments.
Secondary Thunderbolt ports support Thunderbolt 5, 4, and 3 peripherals and can connect up to four additional Thunderbolt devices; the Thunderbolt 5 interface supports 80 Gbps bi‑directional data speed and up to 120 Gbps for higher display bandwidth.
The product includes two Thunderbolt 5 cables engineered to deliver Thunderbolt 5 bandwidth and three Sonnet ThunderLok connector locks to help prevent accidental cable disconnection.
