An XLR to Ethernet converter is an active interface that digitizes balanced analog audio into network packets, so a microphone or mixer can travel over Ethernet as Dante or AES67 audio.
You can’t plug a mic cable into an RJ45 jack, and the reason is electrical: XLR carries balanced analog voltage, while Ethernet carries packetized digital data. Something in between must sample the signal, set a gain, and address it to a receiver on the network.
XLR to Ethernet Conversion: What Happens Inside The Box
Conversion runs in one of two directions, each with a full analog-to-digital or digital-to-analog stage. Nothing is passive wiring.
Analog-to-network: a microphone or line-level source connects to an XLR input; the converter digitizes the signal, applies configured gain and sample-rate settings, packetizes the audio, and sends it out the RJ45 port as Dante or AES67. Dante’s AVIO adapter documentation describes exactly this chain.
Network-to-analog: the device receives a Dante or AES67 stream over Ethernet, converts it back to analog, and presents it on an XLR output for a mixer, amplifier, powered speaker, or recorder.
Routing happens in software, not in the wiring. Dante devices are configured and routed through the Dante network rather than by mapping XLR pins to RJ45 pins, which is why a plain Ethernet cable connected to an XLR output does nothing useful.
What The Current Adapters Can Do
Modern adapters are small, Power-over-Ethernet powered, and spec’d well beyond most rooms. The Dante AVIO Analog line lists XLR and RJ45 connectors, sample rates of 44.1, 48, 88.2, and 96 kHz, 16-, 24-, and 32-bit audio, Dante Audio over IP with AES67 RTP transport, configurable latency of 1, 2, or 5 ms, and Class 1 IEEE 802.3af PoE at under 2 W.
Analog output specs include frequency response of 20 Hz–20 kHz at ±0.5 dB, dynamic range above 100 dB, signal-to-noise ratio above 100 dB, and total harmonic distortion below 0.01% at +4 dBu — figures that keep a short network hop acoustically invisible. Operating temperature is listed at −10 to +50 °C.

| Dante AVIO Analog (ADP-DAO-AU-0x1 / 0x2) | 1 or 2 ch, analog in or out | Up to 96 kHz, 16/24/32-bit, AES67, PoE under 2 W |
| Dante 2CH Analog XLR Input Adapter | 2 ch XLR to Dante | Balanced or unbalanced input, five-level gain, 1/2/5 ms delay, PoE or USB-C |
| Dante 2CH Analog XLR Output Adapter | 2 ch Dante to XLR | Five-level gain, AES67, PoE or USB-C power |
| xIn XLR 4 | 4 ch XLR input | 24-bit, 48/96 kHz, AES67 enabled |
| Soundking CXA036 | 1 RJ45 in, 2 XLR out | PoE from switch or separate injector |
| Blustream DA11AU | 2 ch analog to Dante | AES67 RTP, PoE, 24-bit, 100 Mbps |
| CTP Systems DIO0808MA-XLR | 8 in / 8 out | Gain +65 to −12 dB, phantom power, PoE or AC |
If you’re wiring a rack and weighing which unit fits your channel count, this tested roundup of xlr to ethernet adapters worth buying narrows the field by input type and power.
How Do You Set One Up?
A working setup takes five moves, and order matters because gain and clock problems hide behind each other.
- Connect the XLR source or destination to the converter.
- Connect the converter’s RJ45 port to a suitable Ethernet switch; use a PoE-capable switch or injector when the model requires PoE, per Dante’s AVIO adapter documentation.
- Connect the receiving Dante device to the same Dante network.
- Use Dante Controller or the manufacturer’s control interface to discover devices, set input gain or output level, and route transmitter channels to receiver channels. Dante identifies Dante Controller specifically for latency configuration.
- Confirm sample rate, clocking, channel routing, and analog level before raising the system volume.
When it works, every device shows up in Dante Controller with a green check and your receiver’s channel meter moves when someone speaks into the mic.
What Trips People Up
Compatibility depends on the network protocol, not on an RJ45 socket. Dante devices interoperate within Dante systems; AES67 operation requires compatible AES67-enabled equipment and configuration on both ends.
Power is the second trap. Some models accept PoE only, while others also take USB-C, DC, or mains power — check the exact model first, because a PoE-only unit on a non-PoE switch simply stays dark.
Signal level is the third. XLR microphone-level, line-level, balanced, and unbalanced signals aren’t interchangeable without correct gain and input-mode settings, and excessive gain clips the front end before the network ever sees the audio. Set gain at the converter, not at the far end of the chain.
Common Questions
Can I just solder an XLR connector onto an Ethernet cable?
No. Ethernet carries packetized digital data and XLR carries balanced analog voltage, so the two cannot be joined by wire alone. You need an active converter with an analog-to-digital or digital-to-analog stage inside, plus a network protocol such as Dante or AES67 handling the transport.
Does the converter need a computer to run?
Not for audio transport. Once a Dante converter is configured and its routes are set, it passes audio over the network without a host computer in the signal path. A computer running Dante Controller is only needed for discovery, routing changes, and latency settings, then it can be disconnected.
Will a Dante converter work with my AES67 mixer?
It can, if both ends support AES67 and are configured for it. Dante devices interoperate easily inside Dante systems, but AES67 mode needs compatible AES67-enabled equipment on the receiving side and matching configuration. Verify each unit’s AES67 support, not just its RJ45 port.
