AVMatrix SD1151-12G: Reclocked 12G-SDI Distribution to Five Outputs

The AVMatrix SD1151-12G is a 1x5 12G-SDI reclocking distribution amplifier that fans a single 4K60 SDI source out to five buffered BNC outputs. It is the compact, dependable hub that turns one camera or router feed into a clean signal for every monitor, recorder, and switcher on set. For engineers who cannot risk a dropped 4K feed mid-show, it delivers broadcast-grade distribution in a chassis that fits in a jacket pocket.

What a Reclocking Distribution Amplifier Actually Does

A distribution amplifier takes one SDI input and duplicates it across several outputs, but the SD1151-12G goes further by reclocking every output. Reclocking means it reads the incoming serial signal, re-generates a clean copy timed to a fresh internal clock, and equalizes for the cable loss that accumulates on long BNC runs. The result is that each of the five outputs leaves the box as strong as the original, so downstream gear locks reliably instead of dropping frames on marginal signals. It handles 12G/6G/3G/HD/SD-SDI automatically and is DVB-ASI compatible.

True 12G Bandwidth for 4K60 Workflows

Single-link 12G-SDI carries a full 4K60 image over one BNC cable at 12Gb/s, and the SD1151-12G supports that top rate on the input and all five outputs. Multi-rate auto-detection means the same box also cleanly distributes legacy 3G and HD feeds without any switch to flip. Rated cable reach runs to roughly SD 400m, HD 200m, 3G 120m, and 12G 60m, so it doubles as a signal regenerator that extends usable runs. Embedded audio and ancillary data ride through untouched to every tap.

Optional SFP Cage and Redundant Power

An optional SFP output cage lets you add a fiber module for long-haul or inter-building distribution where copper cannot reach. Two locking DC power inputs provide redundancy: if one supply drops, the second keeps the amplifier and all outputs live, which matters on live broadcasts where a blackout is unacceptable. The all-metal housing includes mounting ears for rack, wall, or under-desk installation and stays cool in continuous operation.

Where the SD1151-12G Fits

Reach for the SD1151-12G whenever one 4K 12G-SDI feed needs to reach many destinations at once: splitting a camera or router output to program monitors, recorders, multiviewers, and a switcher simultaneously. It is a natural fit for OB trucks, live broadcast, houses of worship, and any 12G facility fighting cable loss on long SDI runs. Video engineers, rental houses, and system integrators rely on it as a small, rugged building block for reliable 4K signal distribution.
