Extron LinkLicense (part number 79-2547-03) — the Dual Recording and Streaming upgrade for the 400 GB SMP 351 H.264 streaming media processor.

This is the large-storage counterpart in the SMP 351 dual recording family. The license itself does the same work as its 80 GB sibling: it enables Dual Channel mode, so two archive encoders run side by side and write two independent full-screen recordings and streams, each configured separately. What changes is the headroom behind it. A 400 GB SSD holds roughly 160 hours of 5 Mbps capture, which matters a great deal once every session is being written twice. Advanced audio DSP and streaming presets are part of the same upgrade.

Key Capabilities

• Two archive encoders produce two independent recordings and two full-screen streams.
• Independent archive stream settings on each channel.
• Confidence encoder adds a monitoring stream in two-window or full-screen form.
• Enables advanced audio DSP covering level control, filtering and dynamics.
• Adds streaming presets that reduce per-session configuration.
• Suited to the 400 GB SSD unit: about 80 hours at 10 Mbps or 800 hours at 1 Mbps.

Where It Is Used

High-volume lecture capture rooms recording all day, corporate training centres archiving locally before overnight upload, government and courtroom systems with long retention requirements, and any site where the network share is not always available at capture time.
