Details

Extron DA4 12G HD-SDI (part number 60-1674-01) — a four output multi-rate SDI distribution amplifier in a quarter-rack metal enclosure, covering everything from SD-SDI up to 12G-SDI.

SDI infrastructure tends to be a mix of vintages, and this amplifier deals with that by identifying the incoming rate itself. It locks to any common serial digital rate between 270 Mbps and 11.88 Gbps, adapting automatically to the relevant SMPTE and ITU standard, then equalizes the input and reclocks each output. Practically, the equalizer buys back real distance: roughly 230 feet on RG6 at 12G-SDI, 590 feet at 3G-SDI and 984 feet at SDI. HDR metadata, up to 16 channels of embedded audio, closed caption and time code all pass through untouched. Front panel LEDs report the detected input rate, so a technician can identify a feed without a scope.

Key Capabilities

One BNC input drives four BNC outputs at up to 11.88 Gbps per 12G-SDI connection.
Automatic input equalization for as much as -30 dB of cable loss.
Automatic output reclocking at 270 Mbps, 1.485, 2.97, 5.94 and 11.88 Gbps, selectable per output or bypassed.
Latency of 10 ns with unity gain and 75 ohm impedance throughout.
Handles both level A and level B mapping on 3G-SDI and 6G-SDI.
Front panel USB configuration port for setup and firmware updates.

Where It Is Used

Broadcast facilities and production trucks, live event and house-of-worship video systems, stadium and venue camera feeds, post-production monitoring, and medical or scientific imaging chains that carry SDI to several recorders and displays at once.
