Network to Digital Audio Interface-Dante

Ideal Use Cases

The RDL SF-ND2 is designed for systems that need to convert two Dante network audio signals into left and right digital audio. It provides three digital output connections: a transformer-isolated 110 Ω AES/EBU XLR output, a 75 Ω S/PDIF coaxial RCA output, and an optical S/PDIF output. This combination supports integration with equipment that accepts professional AES/EBU or coaxial or optical S/PDIF signals while keeping Dante audio in the digital domain through the output.

The module is suited to fixed or equipment-rack installations requiring a compact connection between a Dante network and digital audio devices. Its selectable sample rates and multiple output formats allow it to serve systems built around 44.1, 48, 88.2, or 96 kHz digital audio.

Why Choose This Model

The SF-ND2 combines Dante network reception, format conversion, and PoE operation in a single module. It accepts two Dante signals and converts them into a left/right digital audio pair without introducing an analog conversion stage. The digital audio output sample rate follows the selected Dante sample rate, providing a direct relationship between the network source and connected digital equipment.

AES/EBU users receive a transformer-isolated 110 Ω XLR output, while S/PDIF connections are available through a 75 Ω RCA jack or optical output. The unit supports 24-bit audio and does not require special software for module setup.

Installation and Integration

Network connection is provided through an RJ45 port operating at 100 Mbps. Rear-panel Link and Speed indicators show Ethernet connection status, while a front-panel Sync indicator provides network synchronization status. Power is supplied through PoE Class 0 in accordance with IEEE 802.3af, so a separate power requirement is not specified in the supplied product data.

The enclosure measures 2.79 inches wide, 1.68 inches high, and 5.77 inches deep, equivalent to 7.09 by 4.27 by 14.66 centimeters. It is equipped for SysFlex rack mounting or surface mounting. The specified ambient operating range is 0° C to 50° C, allowing installers to confirm environmental compatibility before deployment.

Performance Highlights

The SF-ND2 supports Dante sample rates of 44.1, 48, 88.2, and 96 kHz, with 48 kHz identified as the default. Supported bit depth is 24 bits. Because the output sample rate equals the Dante sample rate, the selected network rate determines the rate delivered to the digital audio output.

Two Dante network audio signals are converted to left and right digital audio while remaining digital through the output path. Available connections include transformer-isolated AES/EBU over XLR, coaxial S/PDIF over RCA, and optical S/PDIF. These documented options allow the module to connect with multiple types of digital audio inputs without claiming support for formats beyond those listed.

What Makes It Different

The defining feature of the SF-ND2 is its combination of Dante reception and three established digital audio connection types in a compact module. The transformer-isolated AES/EBU output addresses 110 Ω balanced digital connections, while the 75 Ω RCA and optical connections provide two S/PDIF options. This gives an installer a choice of XLR, coaxial, or optical connectivity from the same Dante-to-digital interface.

PoE Class 0 operation, visible Ethernet and synchronization indicators, and compatibility with SysFlex rack or surface mounting bring the network, status, power, and placement requirements together in one design.

Final Assessment

The RDL SF-ND2 is a focused interface for converting two Dante network signals into left/right AES/EBU or S/PDIF digital audio. Its 24-bit support, four selectable sample rates, matching Dante and output sample rates, transformer-isolated AES/EBU connection, and coaxial and optical S/PDIF options define its role clearly. With 100 Mbps Ethernet, IEEE 802.3af PoE power, status indicators, and rack or surface mounting capability, it provides the documented essentials for integrating Dante audio with compatible digital equipment.
