Dante-Compliant Audio Interfaces from Studio Technologies
Studio Technologies, manufacturer of professional audio, video and fiber-optic solutions, has introduced the Model 5412 Audio Interface and the Model 5418 Mic/Line Interface, two new Dante-compliant solutions for applications that use Audio-over-Ethernet (AoE) network connectivity.
The Model 5412 supports analogue line-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. The Model 5412 uses 25-pin D-subminiature connectors for easy interfacing with balanced and unbalanced sources and destinations. Low noise, low distortion, and high headroom are key highlights to the audio performance of this unit. Troubleshooting features, including signal loop-back and tone generation, help to ensure successful deployment and operation.
The Model 5418 allows users to connect eight analogue microphone or line-level sources, and then output the signals in the Dante digital domain by way of an Ethernet interface. In addition, eight audio channels that arrive via Dante are converted to analog and output as line-level signals. The eight mic/line audio inputs use standard three-pin female XLR connectors, which are located on the Model 5418’s front panel. The analogue audio input signals are converted to 24-bit PCM digital and then transported via the Dante network interface. The unit offers excellent audio performance with adjustable preamplifier gain, high-pass filters, and P48 phantom power. Control of the operating parameters can be performed locally using the front-panel push-button switches, or remotely using the management web pages or ST controller software application. A monitor section allows both visual and audible observation of the input and output signals.
Both the Model 5412 and the Model 5418 are housed in compact, lightweight enclosures, which mount in one space (“1U”) of standard 19-inch racks. Power can be provided by 100-240 volts, 50/60Hz, or 12 volts DC with redundant operation supported. Both units include three Gigabit Ethernet network interfaces, two to support redundant Dante operation, 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.
