Project Description

DirectOut Technologies MONTONE.42

A bi-directional MADI-to-Ethernet bridge enabling audio channels to be routed as required between up to four MADI streams and two Gigabit network ports, using RAVENNA audio-over-Ethernet technology. The unit is fully compliant with AES67, making it compatible with other AES67-compliant protocols such as Dante, Q-Lan and AVB.

  • Bridge between MADI and Audio-over-IP network audio
  • Interfaces existing MADI streams with standard IP infrastructures
  • Simplifies streaming from MADI sources
  • Uses AES67-compliant RAVENNA audio networking technology
  • RAVENNA offers minimum latency, maximum data transparency and high reliability
  • Full routing matrix – any audio channel(s) at any input may be routed to any output
  • Compatible with all MADI formats – 48/96k frame rate, 56/64 channels
  • Sample rates: 44.1/48/88.2/96 kHz
  • Four MADI I/O ports; may be individually specified as optical SC (singlemode or multimode), coaxial (BNC) or empty SFP carrier.
  • Two Gigabit Ethernet ports
  • Remote control from browser interface
  • Word clock input and output
  • Video sync reference input
  • USB port for firmware updates
  • Network ports may be configured as dual-redundant with auto fail-over
  • Dual internal PSUs

The MONTONE.42 is one of the range of DirectOut MADI interfaces. Other units are available for routing mic inputs direct to MADI (ANDIAMO.MC) and interfacing between MADI and AES3 and analogue (the ANDIAMO range).

Description

Audio-over-IP (AoIP) is being increasingly implemented in broadcast as it enables existing IP infrastructures to be utilised for the transport of high-quality, multichannel audio. With MADI as an accepted standard for multichannel audio within studio environments, the MONTONE.42 allows direct interface between the two systems with full routing flexibility.

The unit allows the broadcast engineer to directly assemble multiple output streams in a fully transparent and compatible IP format directly from MADI audio channels. The unit can also – simultaneously, if wished – extract individual AoIP audio channels from the network and route them elsewhere in the facility as specific MADI channels.

The MONTONE.42 is equipped with four MADI I/O ports, each of which may specified to be i) dual optical SC (singlemode or multimode), ii) dual coaxial on BNCs, or iii) an empty SFP carrier to accept a compatible cartridge of the user’s choice. There are also two standard Gigabit Ethernet ports for connection to the IP network.

Audio-over-IP is achieved using RAVENNA. RAVENNA is a non-proprietary, open-technology standard developed primarily for the broadcast industry, and thus exhibits high data transparency, low latency and excellent reliability. Most importantly, it is fully complaint with AES67, which specifies interoperability with other compliant systems, which currently include Audinate’s Dante, QSC’s Q-Lan, Telos Systems’ Livewire among others.

MONTONE.42 incorporates a full internal routing matrix which permits any audio channel in an incoming MADI or RAVENNA stream to be re-embedded in any outgoing MADI or RAVENNA stream. Access to the matrix – and all other unit setup functions – is via Java-based software accessed through the network ports. Basic settings are also available from the unit’s front panel.

The unit’s sync source may be an internal clock (when the unit is used as a sync grand master), a MADI input, PTP via the network, an externally applied wordclock or video sync (black-and-burst). The unit is compliant with AES11 for clock stability. A USB port is also provided for system firmware updates.

The unit is intended for permanent installation in broadcast studio complexes and transmission centres, and has been designed for fail-safe operation: the network ports may be configured as a dual-redundant pair with auto fail-over, and the unit is fitted with dual internal universal PSUs with separate AC inlets, fuses and AC switches.
