The DAD08/09 Card
Introduction
The Axon DAD08 and DAD09 are Digital Audio Distribution
Amplifiers that distribute a single input to eight outputs. The
DAD08/09 accept AES/EBU or SPDIF (Consumer Interface
Format) digital audio input that is then reclocked, buffered and
distributed to the eight outputs. The DAD08 has transformer
coupled balanced input and outputs, whereas the DAD09 has a
transformer coupled balanced input and direct balanced outputs.
Multiple regenerated independent low jitter outputs make the
DAD08 and DAD09 ideal for the most demanding digital audio
signal distribution requirements in both large and small audio and
video facilities.
Key Features
The Key features of the DAD08 and DAD09 are as follows:
Wide Range Of
Sample Rates
The DAD08 and DAD09 offer a wide range of sample rates.
Sample rates from 24 to 96 kHz are decoded and cleanly
regenerated. Standard sample rates of 32, 44.1, 48, 88.2 and 96
kHz are indicated.
Signal Status
Indication
Signal status and error messages included in the audio data format
are decoded and displayed.
I/O Flexibily
The DAD08 and DAD09 offer a wide range of input and output
options depending on the choice of backplane, giving a high
degree of system flexibility.
Balanced Input: Both the DAD08 & DAD09 offer a transformer
coupled balanced audio input when a backplane is used that
supports the use of three-conductor connections e.g. BPL05.
Balanced Output: The DAD08 offers transformer coupled balanced
audio outputs, whereas the DAD09 offers direct balanced audio
outputs when a backplane is used that supports the use of three-
conductor connections e.g.BPL05
Unbalanced Input: Both the DAD08 & DAD09 can be used with
an unbalanced audio input when a backplane is used that supports
the use of BNC connectors e.g. BPL01
Unbalanced Output: Both the DAD08 & DAD09 can provide
unbalanced audio outputs when a backplane is used that supports
the use of BNC connectors e.g. BPL01
Levels and connectors are optimized for use with balanced XLR
110 ohm cable or unbalanced BNC 75 ohm coaxial cable.
