Studio Technologies Debuts SMPTE ST 2110 Audio Interfaces

Studio Technologies is showing two new audio interfaces for applications that use the SMPTE ST 2110 suite of standards to implement Audio-over-Ethernet (AoE) network connectivity — the Model 5512 Audio Interface and the Model 5518 Mic/Line Interface.

The Model 5518 allows users to connect eight analog microphone or line-level sources and then output the signals in the ST 2110 digital domain via Ethernet. In addition, eight audio channels that arrive via ST 2110 are converted to analog and output as line-level signals. The Model 5512 supports analog live-level inputs and outputs and is available in two versions — one with eight input and eight output channels and the other with 16 input and 16 output channels. Both the Model 5512 and Model 5518 support redundant stream performance using two Ethernet interfaces following the ST 2022-7 standard.

The Model 5512’s analog inputs and outputs use 25-pin D-subminiature connectors for easy interfacing with balanced and unbalanced sources and destinations. With the Model 5518, the unit’s eight mic/line audio inputs are located on the front panel and use standard three-pin female XLR connectors. These analog audio input signals are converted to 24-bit PCM digital and then transported via the AoE network interfaces. Each unit is housed in a compact, lightweight enclosure, which mounts in one space (“1U”) of a standard 19-inch rack. Power can be provided by 100-240 volts, 50/60Hz or 12 volts DC with redundant operation supported.

Both the Model 5512 and Model 5518 include three Gigabit Ethernet network interfaces, two to support ST 2110-30 essence stream transport and the third for accessing the management menu system. An internal web server allows fast and flexible monitoring and configuration of many of the units’ audio and network parameters. In addition, front-panel indicators, a display and pushbutton switches provide users with direct access to key configuration selections.
