MONTONE.42 is a MADI (AES10) to Audio-over-IP bridge based on RAVENNA audio networking technology and supporting AES67 and SMPTE ST 2110-30 / -31. As the demand for Ethernet-based transmissions in professional audio environments increases, MONTONE.42 provides seamless integration of network audio with existing infrastructures.
Equipped with four MADI and two gigabit network ports, it serves as a versatile link for broadcast, live-sound and studio applications. The network ports support redundant audio streaming as per ST 2022-7.

As a successful participant of the JT-NM Tested program MONTONE.42 is listed in the JT-NM Tested Catalog as a device aligning with the SMPTE 2110 standards.

Powerful networking, seamless interoperability
MONTONE.42 integrates RAVENNA networking technology. RAVENNA is a solution for real-time distribution of audio and other media content in IP-based network environments that offers outstanding features in terms of timing accuracy and scalability.
It is also fully AES67-compliant (the interoperability standard from AES) for seamless compatibility with other AoIP devices. MONTONE.42 offers both an AES67 profile for straightforward network integration and RAVENNA profiles for more demanding applications requiring high performance transmission at minimum latency.

Clocking
MONTONE.42 can be synchronized to MADI input, word clock, video reference, network (PTP) or internal clock. The device may also serve as a network grandmaster. The achieved clock accuracy complies with AES11 throughout the whole network.

All-Round Functionality
MONTONE.42 offers highest flexibility as it provides three interface standards for MADI:

optical SC (single-mode or multi-mode)
coaxial (BNC)
SFP
The Small Form Factor Pluggable cage can be fitted with any SFP module suitable for the customer’s application. The configuration of MADI I/Os can be defined individually at order.

Streaming
Assemble up to 32 streams with an individual number of audio channels from the MADI inputs via the integrated routing matrix. Subscribe to another 32 streams and convert the incoming audio channels to MADI.
256 channels are supported even at higher sample rates (96 kHz).

Remote control
An integrated webserver provides access via web browser through the network interface to configure network streams, audio routing and all device settings.
Basic settings are also adjustable via a local interface on the front panel.

Reliable
The MADI inputs can be configured as redundant inputs with automatic fail-over switching.

Safe operation
Thanks to two phase-redundant power supplies with separate IEC inlets and AC power switches on the rear panel the device offers the highest reliability.
