Extron LinkLicense (part number 79-2547-04) — the Dual Recording and Streaming upgrade for the 400 GB SMP 351 with 3G-SDI input.

This is the top of the SMP 351 dual recording range: serial digital video input paired with the largest internal drive Extron offered for the platform. Enabling the license puts the processor into Dual Channel mode, where two archive encoders each write a full-screen recording and stream with their own archive settings, while a confidence encoder supplies a third stream for monitoring. Because a 400 GB SSD stores around 320 hours of 2.5 Mbps material, doubling the recording load does not immediately push capture onto the network.

Key Capabilities

• Dual Channel recording and streaming on the SMP 351 3G-SDI, 400 GB model.
• Two archive encoders, each with independent archive stream settings.
• Confidence encoder produces a two-window or full-screen monitoring stream.
• Enables advanced audio DSP for level control, filtering and dynamics.
• Adds streaming presets for a simplified operating workflow.
• Backed by a 400 GB SSD holding roughly 80 hours at 10 Mbps.

Where It Is Used

Surgical and clinical education theatres feeding SDI cameras, broadcast training facilities, legislative and courtroom recording with long retention rules, and staging environments where professional video and presentation content are archived as separate assets all day.
