Extron LinkLicense (part number 79-2547-02) — the Dual Recording and Streaming upgrade for the 80 GB SMP 351 with 3G-SDI input.

The 3G-SDI variant of the SMP 351 accepts serial digital video from broadcast cameras and professional sources on Channel B. Left standard, it still composites both channels into a single archive. This license changes that: two archive encoders run concurrently, each writing its own full-screen recording and stream with independent archive settings. A third confidence encoder produces a monitoring stream that can be a two-window layout or either channel full screen. Advanced audio DSP and streaming presets come with the upgrade.

Key Capabilities

• Splits the SMP 351 3G-SDI into two independent recording and streaming channels.
• Per-channel archive stream settings instead of one shared composite archive.
• Confidence encoder supplies a separate monitoring stream of both sources.
• Enables advanced audio DSP for level control, filtering and dynamics.
• Adds streaming presets to simplify recurring session setup.
• Applies to the 80 GB SSD unit, holding roughly 16 hours at 10 Mbps.

Where It Is Used

Broadcast-adjacent teaching studios, medical and surgical education suites feeding SDI cameras, houses of worship with professional video chains, and rental and staging work where a serial digital source and a presentation graphic must be archived as separate deliverables.
