4 Analog or 2 or 4 AES Digital Audio to SDI Multiplexer DESCRIPTION
FEATURES
The MXA-3901 provides audio multiplexing into 270Mb/s streams. Accommodation for analog and digital audio interfaces, both balanced 110 Ohm and balanced 75 Ohm are provided. Two stream and four stream AES versions are available. The two stream versions provide processed outputs as well. An integrated audio processing amplifier provides gain, invert, swap, sum and delay functions. This module, as is the case with all modules in the NEO family, can be controlled locally via a front-edge display or by remote communications allowing for remote control, monitoring and diagnostics using hardware control panels and/or a GUI.
