Compact Dante I O Interface for Networked Audio Systems

This 2x2 Dante I O expander is a compact network audio interface designed to add two inputs and two outputs to your Dante-enabled system. Ideal for live sound, installed AV, broadcast, and commercial audio applications, it allows you to connect microphones, line-level sources, and powered speakers directly to a Dante audio network. With support for 48 kHz and 96 kHz operation, this unit delivers high-quality digital audio over standard Ethernet infrastructure.

2 Input 2 Output Dante Expander for Flexible System Integration

Built for scalable audio networking, this Dante I O interface provides two mic or line inputs and two balanced outputs, making it perfect for extending audio to remote rooms, stage boxes, or distributed sound zones. It integrates seamlessly into existing Dante systems, enabling audio routing through compatible digital mixers, DSP processors, and network switches. For system integrators and AV technicians, this expander simplifies signal distribution without running long analog cable paths.

48 kHz and 96 kHz Operation for Professional Audio Quality

Supporting both 48 kHz and 96 kHz sample rates, this Dante interface ensures compatibility with a wide range of professional digital audio systems. Whether used in a live performance environment or a fixed installation such as a conference center or house of worship, it maintains clear, reliable audio transmission with low latency. This flexibility makes it suitable for modern networked audio workflows where consistent sound quality is essential.

Phoenix Euroblock Connectors for Secure Wiring

The unit is equipped with Phoenix Euroblock connectors, providing secure, professional-grade terminal connections for permanent installations. These connectors are commonly used in commercial AV and installed sound systems, allowing clean cable management and stable signal transfer. This makes the interface especially useful in boardrooms, classrooms, hospitality venues, and other environments where reliability and neat wiring are priorities.

PoE Powered or 12 VDC for Installation Flexibility

This Dante I O expander can be powered via Power over Ethernet or an external 12 VDC power supply, offering installation versatility. PoE simplifies setup by delivering power and audio over a single Ethernet cable, reducing clutter and installation time. For systems without PoE-capable switches, the optional 12 VDC input provides an alternative powering method. The external power supply is not included, allowing installers to choose the most appropriate solution for their setup.

Rugged Portable Design for Live and Installed Use

Designed with durability in mind, this compact Dante interface is suitable for both portable and permanent applications. Its sturdy construction makes it dependable for touring racks and mobile production rigs, while its small footprint allows discreet mounting in equipment racks, under tables, or behind displays. For professionals building reliable networked audio systems, this 2x2 Dante expander is a practical and scalable solution.
