AJA OG-12GDA-2x4 openGear Dual 1x4 12G-SDI Distribution Amplifier

AJA OG-12GDA-2x4 is built to distribute two independent 12G-SDI sources inside an openGear rack, giving you clean fan-out without leaning on router outputs or passive loops. It provides two separate SDI input paths, each distributed to four reclocked SDI outputs, so high-bandwidth UHD and 4K signals can be fanned out cleanly inside a centralized rack.

In practical systems, OG-12GDA-2x4 is used when multiple 12G-SDI sources need to feed several downstream devices without relying on router outputs or passive looping. Each input path is reclocked before distribution, helping maintain signal integrity across longer cable runs and complex rack environments.

Highlights

• Dual 12G-SDI distribution: two independent inputs, each feeding four outputs
• UHD and 4K support: handles SD, HD, 2K, UHD, and 4K up to 2160p60
• Reclocked outputs: improve jitter tolerance and downstream stability
• openGear integration: centralized power, cooling, and rack-based deployment
• Dashboard monitoring: configuration and status visibility within facility systems

Quick Specs & Practical Uses

• Inputs: 2x auto-detecting SDI inputs
• Outputs: 8x reclocked SDI outputs (4 per input)
• Supported formats: SD through 12G-SDI (2160p60)
• Signal handling: full reclocking on each distribution path
• Use cases: master control, monitor walls, UHD router fan-outs, OB trucks, flypacks, machine rooms

Signal Integrity & Reliability

Reclocking helps clean up jitter before the signal fans out, reducing intermittent behavior that can otherwise appear downstream. This is especially important when feeding monitors, multiviewers, recorders, and converters from the same source.

Connectivity & Rack Integration

As an openGear card, OG-12GDA-2x4 benefits from shared power and cooling within the frame. Engineers can monitor card status through the Dashboard, making it easier to validate system health during commissioning and ongoing operation.

Centralizing 12G-SDI distribution inside the openGear frame also improves rack hygiene, documentation, and long-term maintainability.

Why It Helps

SDI distribution is simple in theory and unforgiving in practice, especially at 12G. OG-12GDA-2x4 turns two high-bandwidth sources into stable, repeatable fan-out points that behave consistently under load.

It does not add features. It removes uncertainty.
