User Manual  

GENERAL:

The IRT-6400-DAA is designed to provide a solution to most AES/EBU digital audio signal distribution requirements.

A choice of rear assembly is available for either 110 Ohm or 75 Ohm use.

The IRT-6400-DAA can be configured as either a single 1x8 DA or a dual independent 1x4 DA.

The IRT-6400-DAA will operate at AES sample rates from 34 to 54 kHz and may be used with non-AES digital signals that have a net zero DC content. When operating in the 1x8 mode, the alternate input can be used as a reference to which the incoming AES audio can be resampled. An internal reference can be applied to either channel to resample to 48KHz.

The IRT-6400-DAA is designed to fit the openGear® standard 2RU frames which allow a mixture of cards from various manufacturers to be mounted within the same frame.

The DashBoard™ control software is available as a free download.
