D19m AESO – Dual AES/EBU Out, w. Dithering or SFC
1.940.470
The AESO card has been developed for the use in the D19m rack. On one
card, four channels coming from the TDM bus are converted to two
AES/EBU outputs. The signal on the TDM bus is normally coming from the
MADI card (input).
For each of the two AES/EBU outputs individually, either reduced word
length with dithering, or sampling frequency conversion can be jumper-
selected. In dithering mode, output signal resolution is 16 or 20 bit (with
dithering), or 24 bit (without dithering), depending on the front-panel switch
setting. In sampling frequency converter (SFC) mode, the output sampling
frequency is identical to the one of the signal at the AES/EBU sync input.
LED:
SYNC
Indicates that a valid synchronization signal for the SFC is detected at the
AES/EBU sync input.
SUPPLY
Indicates “ power on” status.
Jumpers:
SYNC AES / TTL
This jumper must always be in the SYNC AES position.
SFC / DITHER
Selects the sampling frequency converter or dithering mode, separate for the
two channel pairs 1/2 and 3/4.
