Unleash the Full Potential of Your Pro Audio Workflow Modern creative workstations like the Apple Mac Studio (M3/M4), Mac mini, and MacBook Pro deliver staggering onboard processing power, but they share one major limitation: no PCIe slots. When your workflow demands dedicated DSP, high-track-count audio I/O, or lightning-fast networked audio, you need a solution that won't bottleneck your performance. Enter the Sonnet Echo™ II DV T5 Rackmount.
Designed specifically for the most demanding pro audio, video, and broadcast environments, the Echo II DV T5 is a revolutionary Thunderbolt 5 to PCIe expansion system. Unlike traditional chassis that share a single Thunderbolt bus across multiple slots, this unique 2U rackmount system features dual independent Thunderbolt 5 interfaces—dedicating a massive 6000+ MB/s of PCIe bandwidth directly to each slot.
The Ultimate Hub for Studio & Live Sound Whether you are running dual Avid Pro Tools | HDX cards for massive DSP power, deploying high-density Dante or MADI network cards, or integrating ultra-fast NVMe storage alongside your audio I/O, the Echo II DV T5 ensures that both cards operate at absolute peak performance simultaneously. Zero bandwidth sharing means zero compromises.
Whisper-Quiet for the Control Room We know studio noise floor is critical. Sonnet engineered this unit with dual temperature-controlled, variable-speed Noctua fans. Rated at a virtually silent 17.1 dBA—well below the 20 dBA ceiling required for world-class recording and broadcast studios—the Echo II DV T5 keeps your heavy-duty cards cool without bleeding into your acoustic environment.
Key Features
-
Dual Thunderbolt 5 Interfaces: Dedicated, independent Thunderbolt 5 buses provide full PCIe bandwidth (up to 6000 MB/s) to each slot. No sharing, no throttling.
-
Two Full-Length PCIe Slots: Supports two full-length (up to 12.28"), full-height, single-width non-GPU PCIe 4.0/3.1/2.0 cards.
-
Studio-Silent Cooling: Equipped with dual premium Noctua fans operating at an ultra-quiet 17.1 dBA, perfect for noise-sensitive control rooms and mastering suites.
-
Pro Power for Pro Cards: Features a robust internal 400W universal power supply with two 75W auxiliary power connectors, fully supporting power-hungry hardware like Avid Pro Tools | HDX, AJA Kona, and Blackmagic DeckLink.
-
Rugged 2U Rackmount Enclosure: Housed in a heavy-duty steel chassis that is just 16.5" deep. Perfect for mobile recording rigs, DIT carts, and studio machine rooms.
-
Room to Grow: The Echo II DV T5 module occupies only half of the 2U rack enclosure, leaving space to easily install a second Sonnet module (such as another Echo II or an xMac mini module) side-by-side in the future.
-
Auto Power On/Off: Designed without a traditional power switch, the unit automatically powers on and off with your connected computer, saving energy and preventing accidental shutoffs.
