The AJA 12GDA is a compact 1x6 12G-SDI distribution amplifier useful for rental productions requiring reliable single-link 4K/UltraHD signal distribution. It provides six independently buffered outputs that reproduce the recovered input, with automatic signal detection, re-clocking, and cable equalization to maintain signal integrity over long coax runs.

Key Features

• Compact 12G-SDI distribution, small footprint for easy placement on carts or in tight racks.
• Six separately buffered outputs deliver identical, re-clocked copies of the input for downstream devices.
• Automatic input sensing supports 12G, 6G, 3G, HD, and SD-SDI formats without manual configuration.
• Cable equalization and practical reach for 1694 coax: 12G up to 70m, 6G up to 120m, 3G up to 190m, 1.5G up to 195m, and 270 Mbps up to 405m.
• Passes all ancillary data, preserving embedded audio, timecode, and other metadata.

Use Cases

• Distributing a single 4K/UHD feed to multiple monitors, recorders, or converters on live events or studio shoots.
• Short-run mobile rigs and OB trucks where space is limited and quick setup is required.
• Post and QC workflows that require consistent, re-clocked SDI outputs that retain ancillary data.

Included with your rental

• DWP-U-R1 power supply is included with the rental, ready for immediate operation.
• Unit ships in a compact throw-down package for simple deployment and transport.

Note: The 12GDA is format-agnostic and intended for distribution rather than conversion; ensure source and downstream equipment are compatible with the chosen SDI rate.
