AES/EBU CHANNEL STATUS DATA:
The EQ1 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 output Channel Status Data Bits are generated in the various conversion modes.
Output selected: Consumer format, Input: Consumer format:
All Bits fed forward (transparent), except for Byte 1:
Bits 0...6: 0000000 (category code general)
Bit 7: 1 (original)
Output selected: Consumer format. Input: Professional format:
Byte 0:
Bit 0: 0 (consumer)
Bit 1: 0 (audio)
Bit 2: 1 (copy allowed)
Bits 3, 4: Pre-emphasis according to input
Bit 5: 0 (two 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
Output selected: Professional format. Input: Professional format:
All Bits fed forward (transparent), except for Byte 2:
Bits 0, 1, 2: 001 (max. sample length = 24 Bit)
Bits 3, 4, 5: 101 (24 Bit word-length)
Bits 6, 7: 00
Output selected: Professional format. Input: Consumer format:
Byte 0:
Bit 0: 1 (professional)
Bit 1: 0 (audio)
Bits 2, 3, 4: Pre-emphasis according to input
Bit 5: 0 (source fs locked)
Bits 6, 7: Sampling frequency according to input
Byte 1:
Bits 0, 1, 2, 3: 0001 (two channel mode)
Bits 4, 5, 6, 7: 0000 (no user Bit encoding)
Byte 2:
Bits 0, 1, 2: 001 (max. sample length = 24 Bit)
Bits 3, 4, 5: 101 (24 Bit word-length)
Bits 6, 7: 00
Bytes 3...12: All Bits 0
Byte 23: CRCC byte
Output selected: Transparent. Input: Any format:
All Bits fed forward (transparent), except if EQ not bypassed for Byte 2:
Bits 0, 1, 2: 001 (max. sample length = 24 Bit)
Bits 3, 4, 5: 101 (24 Bit word-length)
Bits 6, 7: 00

FILTERS:
The filter topology used in the EQ1 is a very low noise filter structure for a state of the art performance.
