Studio Technologies Model 5512-02 Audio Interface

The Model 5512 Audio Interface provides a simple yet high-performance means of interfacing analog signals with applications that utilize the SMPTE® ST 2110 suite of standards to implement audio-over-Ethernet networking connectivity. Redundant stream performance is also supported following the ST 2022-7 standard. Line-level analog sources can be connected to the unit and then output in the digital domain by way of the Ethernet interfaces. Digital audio signals, which also arrive by way of the Ethernet connections, are converted to analog and then output as balanced line-level signals. For application flexibility and troubleshooting a configuration choice allows other audio signals to be selected as the sources for the analog output channels. The Model 5512 is available in two versions – one with 8 input and 8 output channels and the other with 16 input and 16 output channels.

The Model 5512 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 24-bit PCM digital and then transported via the Ethernet network interfaces. The destination routing of these signals is performed using commands from the Model 5512's JSON API and related software applications. Digital audio sources associated with ST 2110-compliant devices can be routed to the Model 5512 using JSON API commands. These signals are then converted to analog and provided to users as balanced line-level outputs.

The Model 5512 provides three Gigabit Ethernet ("GigE") network interfaces, two to support redundant operation following the ST 2022-7 standard and the third for accessing the management menu system. An integrated web server allows fast and flexible monitoring and configuration of the unit's networking and audio performance. Front-panel indicators, a backlit LCD display, and pushbutton switches provide users with direct access to key operating parameters.

The Model 5512 can be powered by 100-240 V, 50/60 Hz mains or a source of 12 volts DC. Both can be simultaneously connected to provide redundant operation. The unit's lightweight enclosure mounts in one space (1U) of a standard 19-inch rack. Industry-standard connectors are used for the audio input, audio output, Ethernet, DC power, and AC mains interconnections.

ST 2110 is an emerging technology that is expected to find wide acceptance as an audio, video, and ancillary data transport "backbone" due to its interoperability, flexibility, and expected support by a large number of equipment manufacturers. The Model 5512 can serve as an "edge" device for ST 2110-compliant implementations, providing high-performance line-level analog input and analog output resources in a compact, cost-effective package. The unit can also serve as a general-purpose audio "tool" to help extend ST 2110 capabilities to facilities and applications that were initially implemented to support signals in the analog domain.
