The Studio Technologies Model 5418 Mic/Line Interface provides a simple yet high-performance means of interfacing analog signals with applications that utilize Dante audio-over-Ethernet media networking technology. Eight analog microphone- or line-level sources can be connected to the unit and then output in the digital domain by way of a Dante interface. Eight digital audio signals, which arrive by way of Dante, are converted to analog and then output as balanced line-level signals. Configuration choices also allow other audio signals to be selected as the sources for the analog output channels. A monitor section allows the input and output signals to be selectively observed using meters and a headphone output.
The Model 5418 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 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.
Dante Audio-over-Ethernet
Digital audio data associated with the Model 5418 is interfaced with a local area network (LAN) using Dante audio-over-Ethernet media networking technology. Status LEDs provide a real-time indication of Dante and LAN performance. A major benefit of using Dante is its ability to use any standard Ethernet network implementation, including switches, to directly transport professional audio signals. The Model 5418 supports digital audio signals with a sampling rate of 44.1, 48, and 96 kHz and a bit depth of up to 24. These sampling rates were selected for optimal support of broadcast, production, industrial, and commercial applications.
Network Ports
Using the Dante Controller software application, the Model 5418's two Dante Ethernet ports can be selected to operate in either the switched or redundant modes. In the switched mode a single Ethernet connection is used for interconnection with other Dante-compliant devices. The second Model 5418 Dante Ethernet port can be used to interface with another piece of network equipment. In the redundant mode independent Ethernet connections would be made to the unit's two Ethernet ports implementing Dante's redundant network capability.
Applications
It's suitable for use in demanding on-air broadcast and live-event applications that require both excellent audio performance and reliable operation. The rack-mounted unit is appropriate for installation in fixed locations, serving the needs of systems associated with stadium, worship, education, commercial, and government facilities. Its lightweight enclosure also makes it suitable for mobile and field uses.
The Model 5418 features an optimized set of controls and indicators that makes it simple and intuitive to use. With the unit's headphone and level monitoring resources it's easy for operators to obtain optimal performance. And by providing standard connectors for all inputs and outputs, along with AC mains and DC powering, setup can be completed in just a few minutes.
