Coaxial Digital Audio Outputs
The ADC16 features eight coaxial digital
outputs. There is one RCA coaxial connector
for each pair of digital-audio output channels.
The coaxial outputs are designed to operate
within AES3-id and SMPTE 276M standards,
and drive 1Vpp into 75-Ω. 75-Ω coaxial
cables are required when connecting these
outputs to other devices. Data transmission
errors may occur if the wrong cables are
used.
The coaxial outputs on the ADC16 are DC-
isolated, transformer-coupled, current-
limited, and diode-protected. They
incorporate filtering to minimize RF
interference and susceptibility.
Data Format = AES/EBU professional
Word Length = 24 bits
Sample Rate = 28 to 50 kHz, 75 to
100 kHz, and 150 kHz to 200 kHz
Clock Source = Internal or External
Data Source = A/D or DAW
The digital audio data at the ADC16's digital
outputs can come from one of two sources:
the ADC16's A/D converters ('A/D') or the
optional interface card ('DAW')
The user can select digital output sources via
the 'SOURCE' buttons on the front panel.
Each set of outputs ( 'AES I/O', 'S/PDIF', and
'Optical') has a 'SOURCE' selection button.
These may be used in any combination.
When 'DAW' is selected as the source, the
user can assign any tracks or sub-mixes of
tracks to the coaxial outputs.
