Extron LinkLicense SMP 351 w/ 3G-SDI 400 GB Dual Recording Upgrade

Product Overview

The Extron LinkLicense SMP 351 w/ 3G-SDI 400 GB Dual Recording Upgrade enables independent dual-channel recording on the Extron SMP 351 3G-SDI 400 GB Streaming Media Processor. This SMP 351 dual recording license lets the processor capture two separate MP4 files — Channel A and Channel B — from a single unit, plus unlocks advanced audio DSP for level control, filtering, and dynamics.

Product Description

By default, the SMP 351 3G-SDI 400 GB composites its two encoding windows into a single output file. This LinkLicense changes that behavior so the processor records Channel A and Channel B as two independent MP4 files, and streams two independent videos in Dual Record mode — well suited to broadcast and production environments taking a 3G-SDI camera feed alongside a content source, with the larger 400 GB internal drive giving more headroom for longer recording archives before offloading. The same license also unlocks advanced audio DSP capabilities on the unit, including level control, filtering, and dynamics processing, improving recorded audio quality without an external DSP box in the rack. Because it is a software entitlement, the upgrade is installed via the SMP's embedded configuration page and takes effect immediately — no card swap or hardware downtime. This license pairs naturally with the SMP 351's Kaltura, Panopto, or YuJa integration licenses for automated publishing of the resulting independent recordings.

Key Features

• Independent dual-channel recording — Captures Channel A and Channel B as two separate MP4 files instead of one composite.
• Dual Record streaming — Streams two independent video feeds simultaneously in Dual Record mode.
• Advanced audio DSP — Unlocks level control, filtering, and dynamics processing on the SMP 351 3G-SDI.
• 400 GB recording headroom — Pairs with the larger internal drive for longer archive windows between offloads.
• Per-processor licensing — One license activates one SMP 351 3G-SDI 400 GB unit for the life of the unit.

Typical Applications

• Broadcast and production rooms combining SDI camera and content sources
• Multi-session recording archives before offload to storage
• Lecture capture requiring separate speaker and content recordings

Frequently Asked Questions

Does this license require new hardware?
No. It is a software entitlement applied to an existing SMP 351 3G-SDI 400 GB processor.

Is this license specific to the 3G-SDI, 400 GB model?
Yes. Extron issues a separate SKU for each SMP 351 capacity and I/O configuration — confirm your exact model before ordering. Browse the full Extron SMP Streaming Processors line.

Does this work with the 3G-SDI input specifically?
Yes, dual recording and the audio DSP unlock apply regardless of whether the source feed is SDI or HDMI.

Can Creation Networks help design a dual-channel recording room around this?
Yes. As a certified Extron integrator, Creation Networks designs, commissions, and supports lecture capture and production rooms end to end — see the full Extron catalog or contact our team for a room design consultation.
