Quick Overview

Audio DeEmbedder for 3GSDI stream removes and routes audio data from any SDI source to any four AES/EBU audio outputs



Manufacturer Part Number: GEF-SDI-AUDD

The GefenPRO 3GSDI Audio De-Embedder extracts audio from 3GSDI, Single-Link HDSDI, EDSDI, and SDI video signals. Up to four AES/EBU digital audio streams can be de-embedded and routed to any of the four audio outputs. Selection and routing of each audio group or pair can be configured via RS-232.

How It Works

Connect an SDI source to the SDI In connector. Connect the SDI Loop Out connector to an SDI audio/video device to monitor the original unmodified signal. Connect the Output connector to an SDI acceptor (such as video broadcastequipment). Connect up to four AES/EBU digital audio reproduction devices (such as a DAT recorder or pre-amp) to the Audio Out connectors. Connect the RS-232 cable from the Audio De-Embedder to a PC or automation system to control which audio group or pair will be de-embedded from the video signal. Connect the AC power cord to the 3GSDI Audio De-Embedder and to an available electrical outlet. Once the unit is powered, RS-232 commands can be used to select the audio group and pair to be de-embedded from the video signal.
