Sonnet - 'Echo I Desktop'

Sonnet Echo 1 Desktop

Create ExpansionFor 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.

Thunderbolt Connectivity

Sonnet Echo 1 Desktop

The Thunderbolt ConnectionPlugged into one of your computer’s Thunderbolt 4 or Thunderbolt 3 ports, the Echo I Desktop system enables you to connect one professional PCIe 4.0, 3.0, 2.0, or 1.1 PCIe card to add ports and capabilities your computer lacks.

PCIe 3.0 x16 Slot

Sonnet Echo 1 Desktop

Space and Power to SpareThe 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.

Ultra-Quiet, Dual Fan Cooling Solution

Sonnet Echo 1 Desktop

Dual Fans, Ultra-quiet OperationFeaturing 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.

Included Cable & Locking Mechanism

Sonnet Echo 1 Desktop

Sonnet Thunderbolt 3 Cable & ThunderLok 3Sonnet includes a Thunderbolt cable that supports Thunderbolt's full 40Gbps bandwidth, and is fully compatible with Thunderbolt 4 and Thunderbolt 3 computers. Sonnet also provides a ThunderLok™ 3 Thunderbolt connector retainer clip that prevents accidental cable disconnections — just slide it over one end of the cable, and then plug in the connector and secure it to the chassis by turning a thumbscrew. Because of its unique design, ThunderLok remains on the cable so it won’t get lost when not in use.

Sonnet Echo 1 Desktop

ThunderLok AdvantageSonnet Thunderbolt expansion systems are designed with Thunderbolt ports that include threaded mounting holes for securing Sonnet’s ThunderLok retainer clips that prevent accidental cable disconnections.
