The DAA-4400 is designed to provide a solution to
most AES/EBU digital audio signal distribution
requirements.
The DAA-4400 will operate at any frequency from
34 to 54 kHz and may be used with non-AES digital
signals that have a net zero DC content.
Whilst analogue VDA's may be used for 75 Ohm
AES signals, the digital circuitry of the DAA-4400
offers the advantage of restoring the signal rise and
fall times and output level without the need to
manually adjust gain and compensation controls.
A choice of rear assembly is available for either 110 Ohm
or 75 Ohm use. No changes are required to the main
DA to convert between the two output types.

The input includes both 110 Ohm and 75 Ohm input connectors
and is link selectable on the main PCB.
An optional SNMP (Simple Network Management Protocol) plug-in
module is available for monitoring when used in an IRT frame
fitted with SNMP capability.
The DAA-4400 is designed to fit IRT's standard
1RU and 3RU Eurocard frames and may be used
alongside any other of IRT's analogue or digital
Eurocards.
