Studio Technologies Launches New SMPTE ST 2110 Audio Interfaces
Studio Technologies has introduced two new audio interfaces for applications that use the SMPTE ST 2110 suite of standards to implement audio-over-Ethernet (AoE) network connectivity. Both the Model 5512 Audio Interface and the Model 5518 Mic/Line Interface are included as part of the 2018 IBC IP Showcase, an event hosted by major technical and standards organizations, including the Alliance for IP Media Solutions (AIMS) in which Studio Technologies recently became a member.
The Model 5518 allows users to connect eight analog microphone or line-level sources, and then output in the digital domain by way of an AoE interface. The Model 5512 offers similar digital conversion of line-level analog sources 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 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 units 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 the unit’s audio input and output performance. Front-panel indicators, a display and pushbutton switches provide users with direct access to key operating parameters.
Here are the details.
