Digital audio interfaces accept analog microphones and line-level sources through mic/line inputs, then convert those signals into digital audio for network distribution. Depending on the interface, audio can travel over Dante or AES67 networks to compatible mixers, processors, amplifiers, and other endpoints, with Power over Ethernet (PoE) available on some devices for combined power and data.

Plan for a compatible Power over Ethernet (PoE) network switch and Category cable, such as Cat 5e, Cat 6, or Cat 6A, for PoE-enabled interfaces that carry power, control, and audio data over one connection. Some interfaces also support a local 5-volt power supply, while certain processors use separate Dante or AES67 and control network connections, so verify the device’s power and port requirements before installation.

Choose channel count based on how many sources and destinations must operate at the same time, and match input and output types, such as mic/line, XLR, RCA, 3.5 mm, analog, Dante, or AES67, to the equipment and wiring in the system. Select sampling rates and bit depth that the connected interfaces, processors, and network support, with the product range covering common rates from 44.1 kHz to 96 kHz and 16-, 24-, or 32-bit audio.

Digital audio interfaces can connect microphones, line-level sources, displays, and amplifiers to Dante or AES67 audio networks in residential distributed-audio systems, commercial spaces, and installed AV environments. Common applications include smart displays, home entertainment, meeting rooms, hospitality areas, classrooms, and courtrooms, where networked audio can help place inputs and outputs near the equipment or room where they are needed.
