The Model 5518 Mic/Line 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. Eight analog microphone- or line-level sources can be connected to the unit and then output in the digital domain by way of the Ethernet interfaces. Eight digital audio signals, which 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. A monitor section allows the input and output signals to be selectively observed using a meter function, a headphone output and, if desired, two line-level analog outputs.
