Digibox-D2A - Converts SD, HD, 3G and 6G-SDI to HD/SD component.

Digibox/D2VA serial video to Composite video with analogue audio extractor

The Digibox-D2A allows extraction (deembedding) and conversion of one AES/EBU signal from the eight potentially embedded within the ancillary data space of an SDI signal. The converted signal will typically be a stereo pair, but could also be two mono signals.

A re-clocked SDI output allows the cascading of a number of Digibox units which would allow extraction and conversion of more audio channels.

The audio to be extracted is selected by a rotary switch, and a warning LED indicates if the selected audio is not present. A switch is provided to allow the user to mute the audio outputs. The AES/EBU audio which is to be extracted must be synchronous with the video and sampled at 48kHz and 24bit. The SDI input has automatic cable equalisation for up to 250m of Belden 8281 cable, or similar.

The DigiBox-D2A will find application in temporary and small installations and also where space is at a premium such as in OB trucks. Its small form factor and strong build make it ideal for OB applications. A +12V universal power supply is included with international socket adapters for all countries. Cable tie point.
