Power to Spare

Perfect for AJA Kona 5 Cards or Bluefish 444's Epoch and More!

‍Echo Express SE IIIe includes an auxiliary PCIe power connector, enabling you to install a card requiring extra power, such as the AJA Kona 5 or Blackmagic DeckLink 4K Extreme 12G, and Bluefish444’s Epoch and KRONOS SDI cards.

1. Three PCIe 3.0 x8 slots
2. 6-Pin Auxiliary Power Connector

Ultra-Quiet - Perfect for Noise Sensitive Enviornments

Although thin Mac, Windows, and Linux computers with Thunderbolt 3 ports offer processing power to spare, for many users (such as pros in the creative fields) onboard processing power alone is not enough. Sonnet’s Echo Express SE IIIe is a compact, desktop Thunderbolt 3 to PCIe card expansion system that enables you to connect three professional PCIe cards at the same time to any computer with Thunderbolt 3 ports.

The Echo Express SE IIIe is designed to be ultra-quiet so that it can be comfortably used in noise-sensitive environments. Its enclosure is ventilated front and back to facilitate airflow over the cards bya large, quiet, temperature-controlled fan to efficiently cool the system. The fan automatically speeds up and slows down smoothly as needed—there’s no guesswork in deciding which fan speed to select.
