Extron LinkLicense (part number 79-2547-01) — the Dual Recording and Streaming upgrade for the 80 GB SMP 351 H.264 streaming media processor.

A standard SMP 351 composites its two channels into one archive. This license splits them apart. With Dual Channel mode active, two archive encoders run at once, producing two independent full-screen recordings and two streams, each with its own archive stream settings. A confidence encoder still delivers a third stream that can show either channel full screen or both in a two-window layout, so an operator can monitor the whole capture from one place. The upgrade also opens advanced audio DSP for level control, filtering and dynamics, plus streaming presets that shorten the setup routine.

Key Capabilities

• Creates independent recordings from two different video sources on one SMP 351.
• Separate archive stream settings per channel, rather than a single composited archive.
• Confidence stream composites both channels for single-window monitoring.
• Unlocks advanced audio DSP: level control, filtering and dynamics.
• Adds streaming presets for a simplified, repeatable workflow.
• Targets the 80 GB SSD SMP 351, which holds roughly 32 hours of 5 Mbps recording.

Where It Is Used

Lecture halls capturing presenter and content as separate assets, corporate training rooms that publish two edits from one session, courtrooms and medical education suites where each camera angle must remain a distinct file, and any lecture-capture workflow feeding a content management system.
