RAV.IO is an audio network module for the PRODIGY Series and MAVEN.A to interface RAVENNA streams.
Optional available as RAV.SRC.IO with sample rate conversion (HD SRC) on board.
The PRODIGY Series also offers low latency sample rate conversion (FastSRC™) for input and output.
Three network ports can be configured to connect with two independent networks or for redundant transmission according to ST 2022-7. It interfaces up to 128 audio channels (input and output).
The amount of audio channels is reduced at higher sample rates - 64 channels @ 2 FS or 32 channels @ 4 FS.
RAVENNA is an open audio networking technology developed initially by ALC NetworX.
DirectOut's own RAVENNA implementation relies on more than ten years of development.
As a successful participant of the JT-NM Tested program RAV.IO is listed in the JT-NM Tested Catalog as a module aligning with the SMPTE 2110 standards.

Case Studies
FAQ
What is the difference between single network and dual network A Slot modules?
Single network A Slot modules provide one audio network interface, while dual network modules combine two networking technologies in one card, such as Dante-to-Milan or Dante-to-RAVENNA. Dual network modules are ideal for bridging different audio ecosystems and supporting hybrid workflows.
Which DIRECTOUT devices support A Slot modules?
A Slot modules are supported across several DIRECTOUT smart audio platforms, including PRODIGY.MP, PRODIGY.MX, PRODIGY.MC, and MAVEN.A. The number of available A Slots varies by hardware model.
What is the purpose of SRC in DIRECTOUT module names?
SRC stands for Sample Rate Conversion. Modules with SRC functionality include integrated high-definition sample rate conversion, enabling stable interoperability between devices running on different clock domains or sample rates.
What is the maximum channel count for A Slot modules?
Depending on the module type, A Slot modules can support up to 256 audio channels. Certain high-capacity modules, such as MADI4.IO and RAVENNA modules with optional licensing, offer expanded channel capabilities.
Which audio networking protocols are supported by DIRECTOUT A Slot modules?
DIRECTOUT A Slot modules support major professional audio networking standards including Dante, RAVENNA, AES67, ST 2110, Milan/AVB, and SoundGrid. This flexibility enables seamless integration into modern IP-based audio infrastructures.
