Echo I Desktop

1-slot Desktop Thunderbolt to PCIe Card Expansion System for Computers with Thunderbolt 4 or Thunderbolt 3 Ports

Connect One Full- or Half-length, Single- or Double-width PCIe Card to Computers with Thunderbolt™ 4 or Thunderbolt 3 Ports. For many creative pros relying on recent portable, mini desktop and all-in-one computers to get their jobs done, their computers’ onboard processing power alone is not enough. While these Mac®, Windows®, and Linux® computers include high-performance Thunderbolt ports to support peripherals, they lack PCIe expansion slots to install a specialty card that adds needed storage expansion, video or audio inputs, transcodes data, or connects to high-speed shared storage and networks. Sonnet has a solution — the Echo™ I Desktop. This professional Thunderbolt to PCIe card expansion system enables you to connect one up to full-length (12.28 inches long) single- or double-width PCIe card to your computer via a single cable.

Supports Every Type of Thunderbolt Compatible PCIe Card

Echo I Desktop supports every type of Thunderbolt compatible PCIe 4.0, 3.0, 2.0, and 1.1 card available including video capture and transcoding; audio DSP; 6Gb or 12Gb SAS or SATA host bus adapter; 10Gb or 25Gb Ethernet; SSD storage; and other specialty types to your system.

Do you have a card in mind but aren’t sure it’s compatible? We’ve put together a compatibility list that identifies cards conforming to Thunderbolt technology requirements, and organized by fit and power compatibility with specific expansion systems.

Space and Power to Spare

The Echo I Desktop features one x16 PCIe 3.0 slot, enabling it to support a huge variety of cards, whether single- or double-width, low-profile or full-height. To support power-hungry cards, it integrates a universal 400W power supply and includes a 150W 8-pin (6+2 pin) auxiliary power connector for cards that require extra power (including the Avid® Pro Tools | HDX). The Echo I powers on and off automatically with the connected computer, saving energy in the long run. With no power switch, you can’t forget to turn off the system!

Dual Fans

Dual Fans. Ultra-quiet Operation.

Featuring dual Noctua fans, the Echo I Desktop is designed to deliver ultra-quiet operation so that it can be comfortably used in noise-sensitive environments. Rated at 17.1dBA — below the 20dBA ceiling prescribed for use in recording and broadcast studios — the fans spread the spectrum of their noise to minimize the impact at any single frequency. To further ensure negligible noise levels, the fans are temperature-controlled, automatically speeding up and slowing down smoothly as needed, and the enclosure is engineered to optimize airflow over the installed card to cool the system effectively and efficiently.
