SRC-64 Asynchronous Samplerate Converter Module (optional hardware)
add-on module - available as separate hardware - adds the capability
of asynchronous sample rate conversion to your multiverter. Designed as internal
add-on module, it leaves the
"Extension" port available to
other break-out boxes. (Note: The
module is called "ASRC" in this
manual for clarity).It features
highest analog performance
(THD+N -134dB typ.) , 64-channel,
bi-directional conversion
between any interfaces supported
by the multiverter plus a number
of special modes for maximum
flexibility. The ASRC can be
assigned to any input interface and also any output of the multiverter, giving a true
bi-directional conversion between both clock domains:
The ASRC is inserted (by software) between the selected input and the rest of
the multiverter. The input can run independently, and the ASRC takes care of
matching the data to the main clock of the multiverter.
For the output, the ASRC can be inserted between the main clock of the
multiverter and the selected output. The data is then converted to match the
ASRC's asynchronous clock ("async clock") and sample rate before it is sent out.
Existing multiverter routing capabilities are fully preserved.
Special modes allow the use of two MADI or AES50 ports together, to send and
receive all 64 channels at 96 kHz (48ch for AES50). Conversions between MADI
64ch@96k => MADI 64ch@48k or vice versa - using two MADI ports for the 96k
part and one for the 48k part - are also supported.
