2 AUD-D2A Presentation
2.1 Overview
AUD-D2A is an 8 channels digital to analog audio converter. It has been designed to interface the DCP-2000 (Digital Cinema Server) digital audio output to Analog Audio Processors for theatres without a Digital Cinema Audio Processor.
It accepts digital audio format signal (AES/EBU) as an input and outputs the same signal converted into analog audio format.
The product ships with unbalanced output by default. It can ship with balanced output as well.
The unit has been designed to be rack-mounted. Its dimension is 1RU. It can be mounted either close to the DCP-2000 or close to the Cinema Analog Audio Processor.
2.2 AUD-D2A Front Panel
Its front panel has 2 LEDs:
- one green LED showing when the unit is ON,
- one yellow LED showing the audio activity.

2.3 AUD-D2A Rear Panel
The back panel allows you how to connect the unit to the power outlet (100-240VAC / 50-60Hz).
It has a Power switch for turning the unit ON or OFF.
On the back panel, two DB25-F connectors are available:
- one for the Digital Audio Input,
- one for the Analog Audio Output.
