CHAPTER 4: Operation
Sample Rate Conversion
A switchable sample rate converter is available for the audio network I/O. This is
helpful if the device can't be clocked to the audio network (or act as grandmaster).
The FastSRC™ is a low latency sample rate converter and ensures seamless
exchange between MADI and RAVENNA I/O when both sources are not
synchronised. It is either switchable in the EXBOX Remote or in globcon.
NOTE
When the device is clocked via PTP, it is neither necessary nor recommended to
activate the FSRC.
NOTE
With the FastSRC™ activated at the RAVENNA I/O the trigger signal detection of
EARS™ is limited to Pilot tone - see "EARS™ - Triggering" on page 44.
About FastSRC™
DirectOut's FastSRC™ (FSRC) is a low latency sample rate converter for when two
digital interfaces of a device must work in different clock domains.
FastSRC™ combines good sound quality with very low latency of less than 0.15msecs
and is invaluable in live sound applications and a "life-saver" in critical situations.
High-end sample rate conversion requires noticeable processing time, so for the
very best audio quality we recommend DirectOut's dedicated SRC products such
as the RAV.SRC.IO, DANTE.SRC.IO or MADI.SRC.
