Embed professional analog audio or AES/EBU into an SDI signal, including Ultra HD and 4K DCI formats. The converter suits recorders as well as other SDI devices and converters.

Each of the four jacks carries one analog channel or a pair of AES/EBU channels. Audio is embedded at 48 kHz and 24 bit.
Add audio from the sound control room to SDI.
Embed audio from an analog recorder with the picture.
The signal with audio continues to recorders and other SDI devices.
Add audio channels to video converters.
The converter embeds up to 4 channels of balanced analog audio or up to 8 channels of digital AES/EBU into the SDI signal. Each of the four jacks carries either one analog channel or a pair of AES/EBU channels (1 and 2, 3 and 4, 5 and 6, 7 and 8).

The multi-rate 6G-SDI input detects SD, HD, 3G and 6G-SDI automatically and works with SD, HD, 2K DCI, Ultra HD up to 2160p30 and 4K DCI up to 30p. Reclocking stabilizes the output signal.

In addition to the main SDI input, the converter has a redundant ALT SDI input. If the main signal is lost, for example when a cable is damaged, the converter automatically switches over to the redundant input and the SDI output with audio keeps running.

Audio connects via standard 1/4 inch jacks, so no custom cables are needed. Sampling at 48 kHz and 24 bit matches the television standard, and the audio stays in sync with the picture.

The 4K model is designed for Ultra HD production; for SD and HD up to 1080p60 the more affordable Mini Converter Audio to SDI is enough. Both models have the same audio connections and the same setup with mini switches.

Functions are selected with mini switches using the diagram printed on the converter: analog audio or AES/EBU, sample rate conversion, the channel group in SDI that the audio is embedded into and disabling individual channels. Over USB and the utility for macOS and Windows, settings can be changed from a computer and new software installed.
The Mini Converter range of converters is built for 24/7 operation: the compact metal body fits into a rack in the sound control room, in the studio or in an outside broadcast truck. The connections are easy to reach and use standard cables.

One side has four audio jacks (each for one analog channel or a pair of AES/EBU channels), the other the SDI input, the redundant ALT SDI input, the SDI output with embedded audio and the power input.

The Mini Converter range is designed for professional broadcast, post-production and AV installations. A compact metal chassis, high-quality connectors and standard cabling make it dependable in studios, control rooms and mobile systems.
Core settings are selected with mini switches using the diagram printed on the unit, while USB is used for configuration and updates. The converter handles supported formats automatically and keeps picture and sound stable throughout the signal chain.
