AVMATRIX SD1191 | Professional SDI distribution and amplification

The AVMATRIX SD1191 professional 1×9 SDI amplifier is a solution designed for distributing SDI video signals in broadcast and audiovisual production environments. It allows a single SDI input to be split into nine independent outputs, maintaining signal quality thanks to its reclocking and equalization features.

This equipment is ideal for broadcast installations, mobile units, studios, and any workflow that requires distributing an SDI signal to multiple devices without loss or degradation, maintaining constant synchronisation, signal level, and reliability.

Thanks to its compact and professional design, the AVMATRIX SD1191 professional 1×9 SDI amplifier is ideal for television studios, OB vans, live events, and video distribution systems where signal stability and quality are essential.

Main characteristics:

• 1×9 SDI Splitter: distributes a single SDI input to nine active outputs.
• Compatible with SD/HD/3G-SDI, supporting up to 1080p @ 60 Hz without loss.
• Integrated re-clocking and retiming to restore the signal and improve stability.
• Signal equalisation to compensate for losses due to long cables.
• Independent outputs that maintain integrity without cross-interference.
• Compact and robust housing suitable for racks and technical spaces.
• Compatible with broadcast production environments, OB vans, fixed and mobile installations.

Practical example:

In a live programme production, the main camera transmits via SDI to the AVMATRIX SD1191, which splits the signal and sends it to nine different destinations: the director's main monitor, control room, audio monitor, graphics station and backup monitor. Thanks to re-clocking and equalisation, each destination receives a clean, stable signal with no loss of synchronisation or image degradation, even with long cables.
