MADI (AES10) to Audio-over-IP bridge based on RAVENNA audio networking
technology and supporting AES67 and SMPTE ST2110-30. 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.
A significant update to DirectOut Technologies' MONTONE.42 format
converter adds new capabilities with support for the SMPTE standard ST
2022-7 (stream redundancy).
MONTONE.42 is an AES67-compliant converter that bridges MADI (AES10)
and RAVENNA Audio-over-IP technology. With the arrival of the new
firmware, it now supports the SMPTE standard ST 2022-7, which describes
Seamless Protection Switching between two RTP audio streams. As one of
the first manufacturers to implement ST 2022-7, DirectOut offers
customers an indispensable increase in transmission security for audio
signals in IP networks. Additionally, the two network interfaces - which
are now independently configurable - offer the possibility of operating
audio streaming and device control in separate networks.
The current upgrade of MONTONE.42 marks a further milestone in the
ongoing development of the MONTONE.42 format converter since its launch
two-and-a-half years ago. In 2017, the company added a new, intuitive
and HTML-based GUI and the ANEMAN plug-in for network management and
support of ST 2110-30 and ST 2059-2 to the feature set.
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
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.
MONTONE.42 offers highest flexibility as it provides three interface standards for MADI:
- 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 customer’s
application. The configuration of MADI I/Os can be defined individually
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).
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.
The MADI inputs can be configured as redundant inputs with automatic fail-over switching.
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.
