EXBOX.RAV is an Audio-over-IP to MADI converter running on DirectOut’s well-proven RAVENNA (AES67/ST 2110-30 / -31) implementation. It supports NMOS for stream and device discovery and connection management.
Four gigabit ports with an internal switch and PoE, plus three MADI ports in BNC, SC and SFP format offer bidirectional conversion and routing of 64 audio channels, with built-in SRC functions (FastSRC™) and automatic redundancy switching (EARS™).
The handy size of the popular EXBOX series (1/3 of 19’’), combined with the rock-solid housing and redundant power supplies, makes EXBOX.RAV a compact and affordable solution to migrate baseband audio to IP.
Up to 32 streams with a total number of 64 audio channels are supported. The device complies with AES67, ST 2110-30 / -31, and supports all ST 2022-7 classes.
EXBOX.RAV offers highest flexibility as it provides three MADI ports of different interface types:
- optical SC (single-mode or multi-mode)
- coaxial (BNC)
The Small Form Factor Pluggable cage can be fitted with any SFP module suitable for the particular application.
The FastSRC™ is a low latency sample rate converter, switchable for the audio network I/O, and ensures seamless exchange between MADI and IP when both sources are not synchronised.
Enhanced Automatic Redundancy Switching™ is a system to prevent interruption of the output signal. It uses either the proven BLDS™ technology or pilot tone triggering. A logic monitors the condition of the trigger signal on the RAVENNA input. In case of a failure it switches automatically to the backup input (RAVENNA or MADI).
Two independent NICs can be connected to four network ports of the built-in switch, supporting redundant audio streaming as per ST 2022-7.
Device functions of EXBOX.RAV, such as the channel based routing matrix, FastSRC™ or EARS™ are accessible via globcon and a browser UI. NMOS standards IS-04 and IS-05 are supported for stream and device discovery and connection management.
The device can be powered by up to two external power-supplies as well as PoE (Power over Ethernet).
Each EXBOX can be mounted into a standard 19’’-rack by using the optional kit BOXMOUNT.XL. Up to three devices may fit side-by-side within 1 RU.

DirectOut's FastSRC™ 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.
