Channel Status Data: Input accepts professional or consumer format.
Channel Status Bits
forwarded to AES/EBU output: see table below
Connector: XLR female
AES/EBU Output
Sampling Frequencies: 44.1 kHz, 48.0 kHz, 88.2 kHz or 96kHz
Output Wordlength: 24 Bits
Connector: XLR male
AES/EBU Channel Status Data
The DS1-MK3 allows to convert the incoming Channel Status Data as follows:
∗ From Consumer to Professional
∗ From Professional to Consumer
∗ Transparent mode, i.e. Channel Status Data is fed forward to the output without any conversion
(one exception, see below)
The following tables describe how the Channel Status Data bits are generated in the various
conversion modes.
Output selected: Consumer format.
Input: Consumer format.
Output: All bits fed forward (transparent), except for:
Byte 1: Bits 0..6: 0000000 (category code general)
Bit 7: 1 (original)
Input: Professional format.
Output:
Byte 0: Bit 0: 0 (consumer)
Bit 1: 0 (audio)
Bit 2: 1 (copy allowed)
Bits 3,4: Preemphasis according to input
Bit 5: 0 (2 channel mode)
Bits 6,7: 00 (Mode 0)
Byte 1: Bits 0..6: 0000000 (category code general)
Bit 7: 1 (original)
Byte 2: Bits 0,1,2,3: Sampling Frequency according to input
Bits 4,5: 00 (accuracy grade II)
Bits 6,7: 00
Bytes 3..23: reserved bytes
