Studio Technologies Model 5412-01 Audio Interface

Model 5412 Audio Interface

The Model 5412 Audio Interface provides a simple yet high-performance means of interfacing line-level analog signals with applications that utilize Dante^® audio-over-Ethernet media networking technology. The Model 5412 is available in two versions – one with 8 input and 8 output channels and the other with 16 input and 16 output channels.

Analog sources can be connected to the unit and then output in the digital domain by way of a Dante interface. Digital audio signals, which also arrive by way of Dante, are converted to analog and can be output as balanced line-level signals. For application flexibility and troubleshooting configuration choices allows selection of the audio sources used by the Dante transmitter and analog output channels. This provides digital and analog loopback and test tone capability.

The Model 5412 is a fully professional product that offers the audio quality, features, and reliability required by 24-hour on-air and commercial applications. The analog inputs and analog outputs use 25-pin D-subminiature connectors for easy interfacing with balanced and unbalanced sources and destinations.

The line-level analog audio input signals are converted to PCM digital and then transported via a Dante interface. Using the Dante Controller software application, digital audio signals can be routed (subscribed) to the Model 5412 via the Dante interface.

The Model 5412 provides three Gigabit Ethernet (GigE) network interfaces, two to support redundant Dante operation and the third for accessing the management menu system. To meet the latest interoperability standard the Model 5412's Dante implementation supports AES67-2018. The unit also supports the Dante Domain Manager^™ (DDM) software application. An integrated web server allows fast and flexible monitoring and configuration of the unit's networking and audio performance. Front-panel LED indicators, a backlit LCD display, and pushbutton switches provide users with direct access to key operating parameters
