    M5512A-01 - Overview

    The Studio Technologies Model 5512A 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 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 troubleshooting a configuration choice allows a sine wave tone or the analog inputs to be selected as the source for the analog output channels.

    Audio over Managed IP Networks
    Digital audio data associated with the Model 5512A is interfaced with local area network (LAN) connections following SMPTE ST 2110 standards. A highlight of ST 2110 is the ability to utilize any standard Ethernet network implementation, including switches, to directly transport professional audio signals. For signal integrity the Model 5512A supports redundant audio data streams per the ST 2022-7 standard. The unit is compatible with digital audio signals with a sampling rate of 48 kHz and a bit depth of 24.

    Network Ports
    The Model 5512A's primary and secondary Ethernet ports can be selected to operate in either a switched or a redundant mode. In the switched mode the primary Ethernet port will be used for interconnection with other ST 2110-compliant devices. The secondary Ethernet port can be used to interface with another piece of network equipment. In the redundant mode independent Ethernet connections will be made to the primary and secondary Ethernet ports to implement redundant network capability per SMPTE ST 2022-7.

    The Model 5512A's management Ethernet port will always be used to access the management webpages. This port can be connected to an independent network that some facilities implement for equipment monitoring and maintenance purposes. The unit's management web server can also be connected to the network that is being used for ST 2110 operation.

    Two versions of the Model 5512A Audio Interface are available. The Model 5512A-01 provides 8 line-level analog inputs and 8 line-level analog outputs. The Model 5512A-02 provides 16 line-level analog inputs and 16 line-level analog outputs. Both units are general-purpose interface devices intended for a variety of audio and audio-for-picture applications that utilize the ST 2110 suite of standards. Each is suitable for use in demanding on-air broadcast and live-event applications that require both solid audio performance and reliable operation.

    Notes: Requires SFB running Minuet Firmware v4.5.3-j627 and later.
