Introduction
Overview
The MUX-9258-A provides a cost effective miniature solution to multiplex four
AES/EBU digital audio signals into a 3G/HD/SD-SDI signal.
The MUX-9258-A accepts one SDI signal and provides one processed SDI
output on BNC connectors. The four DIP switch assignable AES/EBU inputs
are also provided on BNC connectors.
Five dual color LED indicators provide SDI and AES/EBU signal status
information. The SDI LED will be illuminated green when a valid SDI signal is
present at the input or illuminated red when no SDI signal is present. The A1,
A2, A3, A4 LED's will be illuminated green when an AES signal is present on
inputs 1 through 4 respectively and available to be multiplexed into the SDI
signal. These LED's will remain off if no signal is present on the respective
inputs.
Power to the MUX-9258-A is provided by an external AC adapter with locking
DC connector supplied with the module.
