Figure 7 – Converting dual AES 24/96 to a single wire double speed one
The dCS 974 converts a 96 kS/s 24 bit Dual AES input to a double speed
96 kS/s 24 bit signal available from any or all of the 4 AES, 2 electrical SPDIF,
optical SPDIF or SDIF-2 outputs. When using the
96 kS/s 24 bit signal available from any or all of the 4 AES, 2 electrical SPDIF,
optical SPDIF or SDIF-2 outputs. When using the
Format Conversion
menu,
the operation is bit for bit on the audio data (messages can be edited).
