MADI (AES10) to audio-over-IP bridge.


As the demand for Ethernet based transmissions in professional audio environments is increasing, MONTONE.42 provides seamless integration of network audio with existing infrastructures. Based on the Ravenna network standard and MADI (AES10) it serves as a versatile link for broadcast, live-sound and studio applications.


MONTONE.42 is equipped with four MADI and two gigabit network ports. Up to 32 Streams, 256 channels, Sample Rates up to 192 kHz with support for AES67 & SMPTE / ST2110-30.


The device can be synchronized to MADI input, word clock, video input (black burst), network (PTP) or internal clock. When set to internal clock, it may also serve as a network grandmaster. An AES67 compatible profile is available in MONTONE.42 to ensure seamless interoperability with other audio-over-IP devices. Beyond that, native Ravenna profiles can be used for e.g. high-performance transmission at minimum latency.




A fresh software update to DirectOut’s MONTONE.42 MADI/Audio-over-IP bridge brings greatly improved usability and increased flexibility.


With a user interface that has been completely revised and is now based on HTML5 and java-script, a new menu structure provides quick access to all relevant system and streaming information. Detailed adjustments can be made in the Advanced Settings area, ensuring that MONTONE.42 can be used in demanding and complex network infrastructures where the ability to adjust parameters – like QoS and PTP values – is key.


Using a native RAVENNA implementation, MONTONE.42 already supports the coming SMPTE ST2110-30 standard. This facility includes the ability to synchronize to Grandmasters running the SMPTE ST2059-2 PTP profile.


Recognising an increasing demand for network-based transmission and control in professional audio environments, MONTONE.42 is designed to be an inherent part of many of the latest IP-based media networks. The new interface provides seamless integration of networked audio with existing infrastructures, and allows the unit to serve as a versatile link in broadcast, live sound and studio applications.


Over the past two years of service, MONTONE.42 has proven itself to be a powerful and highly interoperable system, and constant improvement of the adoption and implementation of new standards ensures that it will remain the path of choice for migration to networked media operation.
