Maximize Your PCIe Card Investment
Using a video, audio, storage, network, or even gaming PCIe card with a Mac Pro or PC desktop is a simple matter of inserting your card into an open slot. But what do you do if you have a laptop or even a space-confined desktop like an iMac or Mac mini that doesn't contain a PCIe slot?
The Mercury Helios 3S is an easy to use yet powerful expansion solution that adds an external PCIe slot to your Thunderbolt 3 equipped computer. Now you can maximize your existing PCIe card investment — or expand it! — while enjoying the flexibility of adding professional-class video production, transcoding, audio processing, data storage, and high-speed network connectivity to your machine.
Retask Without Limits
Instead of buying one or more function-dedicated Thunderbolt interface devices, you can use Mercury Helios 3S like a dock for multiple PCIe cards. Capture incredibly high-quality audio with a PCIe audio card and then retask 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 40Gbps Thunderbolt 3 (Thunderbolt 2/Thunderbolt backward compatible), 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.
