Channel status data: input accepts professional or consumer format
The channel status data bits forwarded to AES/EBU output: see the table below
Connector: XLR female
AES/EBU output
Sampling frequency: 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz(Always the same as the input)
Output word length: 24 bits
Connector: XLR sub
Channel state data
DS1 allows the input channel state data to be converted as follows:
From consumer to professional
From professional to consumer
Transparent mode, that is, channel state data is fed to the output without any conversion(One exception, see below)
The following table describes how to generate output channel status data bits in various conversion modes.
Output selection: consumption format, input: consumption format:
All bytes are fed forward(transparent), Except byte 1:
Bit 0…6: 0000000(General category code)
Bit 7:1(Original)
Output options: consumption format, input: professional format:
Byte 0:
Bit 0:0(consumer)
Bit 1: 0(Audio)
Bit 2: 1(Allow copy)
Bit 3, 4: Pre-emphasis based on input
Bit 5:0(Dual channel mode)
Bit 6, 7:00(Mode 0)
Byte 1:
Bit 0…6: 0000000(General category code)
Bit 7:1(Original)
Byte 2:
Bits 0, 1, 2, 3: According to the input sampling frequency
Bit 4, 5: 00(Accuracy class II)
Bit 6, 7:00
Byte 3…23: reserved byte
Output options: professional format, input: professional format:
All bytes are fed forward(transparent), Except for byte 2:
Bit 0, 1, 2: 001(Maximum sample length = 24 bits)
Bits 3, 4, 5: 101(24-bit word length)
Bit 6, 7:00
Output selection: professional format, input: consumption format:
