When your multicam live event production, documentary, news or sports programming is captured to AJA Video System’s Ki Pro Ultra 12G 12G-SDI4K/UHD/HD recorder and player, your footage is recorded on ultra-reliable AJA PAK Media SSD cards. With the recorder’s ability to support four channels of simultaneous 1080p at 60 fps recording — or a 4K at 60 fps recording in single-channel mode — those cards fill up fast. The need for a tool that accelerates offloading media files from multiple cards is greater than ever, too. Sonnet SF3™ Series - AJA PAK Media Pro Card Reader is the perfect tool for the job.

Certified by AJA, this Sonnet media card reader ingests media files from PAK Media memory cards at the fastest speeds the cards will support to any computer with Thunderbolt ports. And, for even greater efficiency, it can ingest files simultaneously from two cards at high speed — up to 1030 MB/s — to cut your ingest times in half.
Ingests footage from all AJA PAK media cards at maximum supported speeds.
Dual card slots enable simultaneous ingest of files from two cards for greater efficiency, up to 1030 MB/s aggregate.
Pro media card reader provides four lanes of PCIe bandwidth for maximum performance.
Small and rugged aluminum enclosure for reliable operation; design enables multiple SF3 Series card readers to occupy same footprint.
Threaded mount points enable secure attachment of two readers side-by-side on a rack tray in just 1U of rackspace.
One port connects to computer; second port supports daisy chaining additional card readers.
Compatible with Mac and Windows. See Tech Specs for details.

Because Sonnet’s PAK media card reader features a dual-port, high-bandwidth Thunderbolt interface, you can daisy chain up to six of them together to a single port on your computer. Connecting three readers to your computer enables you to ingest six cards simultaneously at full speed to complete the process — without swapping cards — in about one sixth the time required using a single-slot reader!

Sonnet’s SF3 Series Professional Media Card Readers include threaded mount points that enable you to securely attach two readers side-by-side on a rack tray in just 1U of rack space.
For DITs working multi-camera shoots or in a small space, equipment size and design features matter. Sonnet’s PAK media card reader measures just 5.8 inches wide by 6.1 inches deep by 1.4 inches tall, making it suitable for use in any workspace and workflow.
Sonnet Thunderbolt products feature a high-speed Thunderbolt interface that delivers PCIe bandwidth needed to support data transfers at full speed.
Many Sonnet Thunderbolt products featuring Thunderbolt ports come equipped with threaded mounting holes to securely attach a Sonnet ThunderLok connector lock, preventing Thunderbolt cables from accidentally disconnecting.
SF3 Series Professional Media Card Readers are purposely designed with a Thunderbolt 3 controller and its four lanes of PCIe (not available in a Thunderbolt 4 peripheral) to achieve maximum simultaneous ingest speeds. Watch this video to learn more about the performance benefits.
