ML-16D/ML-32D
16/32-Channel Analogue-Dante-Analogue Converter
ML-16D and ML-32D are compact, high-quality analogue-Dante-analogue converters designed to transfer 16 or 32 analogue audio channels over a Dante network in both directions. Space-saving 25-pin D-sub connectors are provided for use with optional breakout boxes to input and output balanced, line-level analogue audio signals. Two Ethernet connectors (Dante Primary/Secondary) are available for redundant operation using two separate networks.
The units feature indicators for operation status and current sample rate as well as overload LEDs for each input and signal LEDs for each input and output. Switches on the rear side allow the user to set the required maximum input/output level. Any other settings, such as sampling frequency, channel routing or latency, can be made by the freely available “Dante Controller” computer application.
Dante is a network technology by Audinate offering high-performance audio distribution over standard IP networks. It supports hundreds of simultaneous channels of uncompressed audio with ultra-low latency and accurate synchronization.
Now compatible with SMPTE ST 2110-30
With Dante module firmware V1.2.0, the ML16D/ML-32D now support SMPTE ST 2110-30, which will enable smooth IP transmission of PCM digital audio for structuring broadcast systems.
* Dante Domain Manager (DDM) v1.1 or higher is required for data transfer according to SMPTE ST 2110-30. For more information about DDM, please visit the Audinate website.

About SMTPE ST 2110
ST 2110 is a video and audio IP network standard defined by the Society of Motion Picture and Television Engineers (SMPTE). SMPTE ST 2110 is designed to separately embed and transmit video, audio, and ancillary signals, reducing the processing load for de-embedding and network load of each device, while also enabling users to de-embed only the packet data they desire for further edit. ST 2110-30 defines framework conditions for the IP transmission of PCM digital audio, enabling high-precision synchronization using PTP (IEEE1588-2008) and low latency. It is expected to become a network standard protocol in next-generation broadcasting systems.
Transfer up to 32 line signals over a network with one device
The Dante network protocol enables building highly stable and flexible audio systems. Use a ML-32D to easily set up a 32-channel audio transmission line between, for example, a stage and a control room via a Dante network connection.
Two network connectors for redundant transmission lines
Using their primary and secondary connectors, ML-16D/ML-32D can be connected to two Ethernet network infrastructures at the same time. Should the main line (the primary network route) fail, the unit automatically switches to the spare line (the secondary network route). This way it is possible to build a highly secure audio system which does not cause an interruption or noise at all at the time of switching the networks.
Flexible routing to other devices in your Dante network
The ML-16D/ML-32D uses Dante Controller for its own configuration and to connect to other devices within the Dante network. Using Dante Controller, you can flexibly route any single input and output channel to and from any other available Dante-compatible device.
About Dante Controller
Dante Controller is a free software application provided by Audinate. The latest version is available at the Audinate website: https://www.audinate.com/products/software/dante-controller
Possible to interconnect with AES67 and Ravenna systems
ML-16D/ML-32D also supports the AES67 network standard making it possible to interact with AES67-compatible audio networks including Ravenna.
Signal and overload indicators for each analogue input and output
ML-16D/ML-32D offer indicators to monitor signal present and overload conditions for each analogue input and output.
System status visible at a glance
Three LEDs show the current sampling rate and a blue/red status indicator informs about audio muting as well as any Dante malfunction or error.
Five selectable reference levels to adapt to your systems
The ML-16D/ML-32D offers five reference levels to be selected according to your technical environment. Whether used in a recording studio, broadcasting studios, sound reinforcement installation, or PA system – the appropriate level can easily be selected by DIP switches.
Compact audio connectors for flexible use with breakout boxes
Audio inputs and outputs of the ML-16D/ML-32D are available via D-sub 25-pin connectors. The advantage is that you can decide for yourself which connections you want to use. Tascam offers suitable breakout boxes with balanced Euroblock terminals or balanced male or female XLR connectors. Euroblock is ideal for a fixed configuration in permanent installations while XLR is more convenient when you change equipment more often.
