Professional 12G-SDI Audio Converter

The AJA 12G-AMA is a mini-converter designed for professional video workflows. It embeds or disembeds four channels of balanced analog audio through XLR breakout connections. The unit handles 12G-SDI signals up to 4K UltraHD at 60p. Free Mini-Config software provides control via USB.

Suited for broadcast and live production teams

Engineers who need precise 24-bit audio conversion alongside 12G-SDI routing will benefit from the flexible embedder and disembedder modes. Fiber options extend signal reach for remote camera positions. This device does not serve users who require HDMI or DisplayPort interfaces, nor does it support unbalanced consumer audio connectors without external adapters.

Check your 12G-SDI cabling and power plan

Verify that existing coax runs meet the 65m limit at 12 Gbps using Belden 1694A or equivalent cable quality. Confirm the locking power connector matches your rack or camera-rig power distribution. Ensure a USB port is available on a nearby computer for Mini-Config setup and firmware updates. The universal supply includes international plugs for global locations.

Questions about this item

Does the AJA 12G-AMA need a separate power source or can it run from the camera rig?

It includes a universal power supply with international plugs and a locking connector, plus an optional P-TAP cable for camera-rig power.

Will the 12G-SDI input on the 12G-AMA accept an older 3G-SDI camera signal?

The unit handles SD, HD, 2K, UltraHD and 4K formats, so legacy 3G-SDI sources pass through without extra adapters.

How can I confirm the 12G-AMA is passing 4K at 60p with 24-bit audio after setup?

Connect via USB and open the free Mini-Config software; it reports the active input and output formats and all audio channel status in real time.
