Description

The For-A UFM-30DEMUX is a module-type digital audio de-multiplexer designed to extract 8-channel AES/EBU signals (4 stereo pairs) from 3G-SDI, HD-SDI or SD-SDI signals. ANC time code can be output as LTC by switching an AES output to LTC output.

Available Configurations Include:

UFM-30DMXAO

UFM-30DEMUX Analog Audio Output Option

Features

UFM-30DEMUX features include:

De-multiplexes 4 pairs of AES/EBU signals (8 channels) from SDI signals
Supports 3G-SDI Level A/B
Sixteen channels of embedded audio can be assigned to 8 arbitrarily selected AES channels*
Supports asynchronous embedded audio de-multiplexing
Supports remapping and multiplexing of embedded audio onto SDI signals after de-multiplexing and remapping
Switching from AES OUT 7/8 to LTC OUT allows LTC output support. ANC time code can be output as LTC
Enables SDI signal input to bypass output when the power is turned off or By-pass mode is selected
UFM-3DMXAO: Analog audio output option. Equipped with connector for independent LTC time code output
*With asynchronous audio sources, audio channels can be freely mapped on a per-group basis, not per-channel
