Jan Ehrlich from Directout Technologies showed Mike Thornton the 3 Audio Over IP Bridging Units in their range, the Monotone 42 MADI to Ravenna converter, the SG.MADI - MADI to SoundGrid Convertor and the EXBOX.MD - MADI to Dante Converter on the Aspen Media stand at BVE in London.

Directout Technologies Monotone 42 MADI to Ravenna converter

The Monotone 42 MADI to Ravenna converter is a bidirectional 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 compliant protocols such as Dante, Q-Lan and AVB.

Directout Technologies SG.MADI - MADI to SoundGrid Converter

The SG MADI - MADI to SoundGrid Converter is a bidirectional audio format converter which interfaces MADI signals with a Waves SoundGrid network. SG.MADI simplifies interfacing live broadcast or studio systems with SoundGrid-based consoles and plug-in servers. It caters for all copper and optical MADI formats and includes analogue I/O and GPIOs, making Waves plug-ins in a SoundGrid DSP Server accessible to MADI or local analogue signals, or for local break-in/break-out applications such as the use of hardware processors.

• Uses Waves’ SoundGrid AoIP networking technology
• SoundGrid offers 128 uncompressed audio channels with low latency
• Allows local I/O to access Waves plug-ins
• AoIP channels can access external hardware processing
• Two mic level analogue inputs with switchable pads
• Two analogue line outputs
• Headphone output
• Front panel level controls for headphones and analogue outputs
• 2 x GPI and 2 x GPO ports
• Compatible with all MADI formats – 48/96k frame rate, 56/64 channels, S/MUX: formats are assignable on a per-port basis
• Sample rates: 44.1/48/88.2/96 kHz
• Two modular MADI I/O ports; may be individually specified as optical SC (singlemode or multimode), coaxial (BNC) or empty SFP carrier
• Two Gigabit Ethernet ports
• Supports parallel 2 x 64 channel operation for redundant recording
• Remote control through browser pages within SoundGrid application
• Word clock input and output
