AVMatrix SD1141 1x4 3G-SDI Distribution Amplifier

Compact 3G-SDI Distribution Amplifier for Professional Video Signals

The AVMatrix SD1141 is a compact 1x4 3G-SDI distribution amplifier designed to take a single SDI video signal and distribute it to up to four separate SDI outputs simultaneously. It is built for professional video environments where one reliable SDI feed needs to be sent to multiple monitors, recorders, switchers, or broadcast devices without signal degradation. This makes it a practical solution for studios, live production setups, OB vans, and fixed AV installations.

Reliable Signal Splitting with Reclocking and Buffering

At the core of the SD1141 is reclocking technology that regenerates the SDI signal before it is distributed to each output. Each of the four outputs is independently buffered, helping maintain signal integrity over longer cable runs. This ensures clean, stable video delivery and minimizes issues such as jitter, signal loss, or timing errors when feeding multiple downstream devices.

Automatic SDI Format Detection for Flexible Workflows

The distribution amplifier automatically detects incoming 3G-SDI, HD-SDI, or SD-SDI signals, removing the need for manual configuration. This allows the SD1141 to adapt quickly to different video formats and production requirements, whether working with standard definition legacy equipment or modern high-definition workflows. Automatic detection helps streamline setup and reduces the risk of format mismatches during live operation.

Support for Embedded Audio and Ancillary Data

Embedded audio is passed through all outputs without alteration, preserving synchronization between video and audio signals. Ancillary data contained within the SDI stream is also maintained, ensuring compatibility with professional broadcast and production equipment that relies on metadata, timecode, or control information. This makes the SD1141 suitable for both simple monitoring tasks and more complex signal distribution chains.

Miniature Form Factor for Tight Installations

The small, lightweight design of the SD1141 allows it to be easily integrated into tight rack spaces, flypacks, or behind-the-scenes installations where space is limited. Its low-profile build makes it ideal for mobile production kits and permanent installations alike, providing dependable SDI signal distribution without adding unnecessary bulk or complexity.

Designed for Consistent Performance in AV and Broadcast Environments

Built for continuous operation, the SD1141 is well suited for professional AV, broadcast, and live event environments where consistent signal performance is critical. By combining reclocking, buffering, and automatic format detection in a simple device, it offers a dependable way to manage SDI signal distribution across multiple endpoints.
