POSITIONS ON THE BOARD
3.5.1. Selection of 20 or 24 bits
The DAR3000C01 module can deliver audio sampled at 20 or 24 bits in the AES/EBU
stream. This selection is made via switch 1 of S1 as shown in the following table:
MODE SW1
20 bits OFF
24 bits ON
3.5.2. Selection of the audio tone level
When the module generates audio tones, their level can be set to 0 dBfs, -18 dBfs or
-20 dBfs. This selection is made via switch 2 of S1 as shown in the following table:
LEVEL SW2
0 dBfs OFF
-18 dBfs ó -20 dBfs ON
Selection of -18 dBfs, -20 dBfs, the frequency of the audio tones and the insertion of
periods of silence for channel identification can only be done via the module's control
software, and this requires that a communications controller be installed in the same
mounting frame. The module is configured at the factory such that the ON position of
the switch 2 selects -18 dBfs.
