Supports AJA PAK Media Cards at Full Speed

Superior Dual-sot Ingest Performance

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.

Ingest Simultaneously from Two Cards

Dual Card Slots, Double Productivity

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.

Ingest Six Cards Simultaneously

Daisy Chain Power

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!
