DIRECTOUT RAV.RAV.SRC.IO
DirectOut RAV.RAV.SRC.IO
RAV.RAV.SRC.IO to podwójny moduł sieciowy audio dla serii PRODIGY i MAVEN.A umożliwiający obsługę dwóch 64-kanałowych strumieni RAVENNA.
One module, two audio engines
Moduł wyposażony w dwie karty sieciowe audio oferuje 2 x 64 kanały RAVENNA. Można go podłączyć do dwóch różnych środowisk RAVENNA, każde z 64 kanałami, i zapewnia płynne przełączanie między sieciami w trybie redundancji.

Sample Rate Conversion
A custom HD SRC chip for bidirectional sample rate conversion is built in as standard.
The two audio network cards can operate at different sample rates.
Dual network modules provide a seamless connection between clock boundaries and different audio protocols in a single module.
Redundant streams
There are 2 x 2 independent network interfaces to connect each protocol via a second stream (primary/secondary or Port 1 / Port 2).
The number of audio channels per protocol is reduced at higher sampling rates - 32 channels at 2 FS or 16 channels at 4 FS.
RAVENNA is an open audio networking technology initially developed by the ALC NetworX.
DirectOut's own implementation of RAVENNA is based on more than a decade of development.
As a participant in the JT-NM Tested program, RAV.IO is listed in the JT-NM Tested catalog as a SMPTE 2110 compliant module.
