Capture high-quality audio with a PCIe audio card and then retask the Helios 3S with a PCIe SSD card to edit and archive tracks. You can swap cards in minutes, adding a new level of flexibility to your workflow.
Capture, Stream, and Share in Seconds
With dual 40 Gb/s Thunderbolt 3 ports that are backward compatible with Thunderbolt 2 and Thunderbolt, the Mercury Helios 3S offers the bandwidth needed to support data-intensive 4K capture cards to speed up diverse video workflows such as vlogging. Boost your DAW with external DSP acceleration and run larger mixes with multiple plug-ins. Livestream the action in your gaming sessions or share files over a 10GbE or Fibre Channel network without any speed throttling.
