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 theaters
without a Digital Cinema audio processor.
It accepts digital audio format signal (A S/ BU) as an input and outputs the same signal converted
into analog audio format. The product ships with unbalanced output only. 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 L Ds:
•one green L D showing when the unit is ON
•one yellow L D showing the audio activity.
Figure 1: AUD-D2A Front Panel
2.3 AUD-D2A Rear Panel
The back panel allows you to connect the unit to the power outlet (100-240VAC / 50-60Hz). It has
a power switch for turning the unit ON and OFF.
On the back panel, two DB25-F connectors are available:
•one for the Digital Audio Input
•one for the Analog Audio Output

.2.3 Step 3: Connecting the AUD-D2A Power Cable
Plug the power cable into the AUD-D2A and power it ON by putting the power switch in the ON
position as illustrated in Figure 9 above. The power L D of the front panel should light ON (green
L D). If any activity is detected, the “active L D” (yellow L D) should be lighted – see Figure 1.
