The Echo Express III D Desktop Thunderbolt 2 Expansion Chassis from Sonnet enables you to connect three compatible full size professional video capture, audio interface and other special purpose cards to your iMac, Mac mini, MacBook Air, MacBook Pro or the new Mac Pro with a Thunderbolt port. The Echo Express III D integrates a universal 300W power supply and includes a 75W auxiliary power connector for cards that require supplementary power. The expansion chassis is eco friendly as it automatically powers off when the connected computer is powered off or in sleep mode. The use of larger, slower spinning fans in the Echo Express III D reduces noise. Two Thunderbolt 2 ports support daisy chaining of up to six devices to a single port on your computer.


The original 10 Gb/s Thunderbolt interface has provided breakthrough bandwidth for external expansion, which is more than sufficient to support the maximum performance of most PCIe cards. However, some high bandwidth cards such as the RED Rocket, 16 Gb Fibre Channel, multi port 10 Gigabit Ethernet cards, or multiple bandwidth hungry cards require more than 10 Gb/s. Thunderbolt 2 overcomes this barrier by providing a higher bandwidth of up to 20 Gb/s for these demanding applications.
