2 D19m MODULES
2.1 A/D and D/A Cards
2.1.1 D19m C4AD/24 – Quad 24 bit A/D Converter
1.940.562
The A/D card uses high-end 24 bit Delta-Sigma converters and can be used
for standalone applications as well as for the D19m rack. On one card, four
analog inputs (mono) are converted to two AES/EBU outputs; if a MADO
card is used in the system, these signals can be converted to a MADI link.
If the external sync signal fails or if the card is used in standalone applica-
tions, the sampling frequency will be generated on-board. For such cases the
sampling frequency can be selected at the front panel (44.1 or 48 kHz).
The channel status information contains the sampling frequency as well as
source channel information depending on the card address.
