DXA-USB-ED Overview and Use Cases – OREI

What Is the DXA-USB-ED?

The OREI DXA-USB-ED is a 2-channel Dante® USB Transceiver that bridges USB audio devices with professional Dante® networks. Based on the Dante® Ultimo platform, it functions as a high-quality USB sound card, enabling seamless transmission of analog audio over standard IP networks with full AES67 compatibility.

It delivers high-resolution audio at 24-bit depth with sampling rates of 44.1 kHz, 48 kHz, and 96 kHz, and is compliant with USB Audio Device Class v1.0. The device can be powered via USB (5V) or Power over Ethernet (PoE, IEEE 802.3af Class 0), making it a plug-and-play solution for live sound, recording studios, and broadcast environments.

IMPORTANT — DXA-USB-ED Connects USB Audio Devices to a Dante® Network

The DXA-USB-ED is designed for users who need to integrate a standard USB audio device — such as a laptop, computer, or USB microphone — into a professional Dante® audio-over-IP network.

Common use cases include:

Connecting a laptop or PC to a Dante® network for live sound applications
Integrating USB audio sources into broadcast or studio environments
Routing audio from a computer to Dante®-enabled speakers, mixers, or amplifiers
Using a computer as a Dante® transmitter or receiver alongside other Dante® devices

IMPORTANT — Audio Routing Requires Dante® Controller Software

The DXA-USB-ED does not have physical input or output audio connectors beyond the USB port. All audio routing between Dante® network devices is managed using the free Dante® Controller software.

The device will appear in Dante® Controller as a transmitter and receiver, allowing its audio channels to be patched to and from other Dante®-enabled devices on the same network. Basic USB audio playback and recording on the host computer does not require Dante® Controller.

IMPORTANT — DXA-USB-ED Does Not Have Analog Audio Ports

The DXA-USB-ED is a digital bridge between USB audio and Dante® network audio. It does not include XLR, TRS, or RCA analog connectors.

If you need to connect analog audio sources (such as microphones or line-level devices) directly to a Dante® network, use a Dante® analog encoder instead.

Ports and Panel Layout

Port / LED	Location	Function
USB	Side panel	2-channel USB digital audio port. Supports L/R mixed audio input and L/R stereo audio output. Also provides 5V USB power from the connected device.
DANTE (PoE)	Side panel	RJ45 port for Dante® network audio transmission and PoE power input (IEEE 802.3af Class 0). Green LINK LED stays steady when the network connection is established. Yellow DATA LED blinks during active Dante® audio data transmission.

Step-by-Step Setup

Connect the included USB cable from the DXA-USB-ED's USB-B port to a USB-A port on your computer or USB audio device.
Connect a CAT6 or CAT6A Ethernet cable from the DANTE (PoE) port on the DXA-USB-ED to a network switch on your Dante® network.
Power the device via the USB connection (5V from the host device) or use a PoE-capable switch to supply power through the Ethernet cable (IEEE 802.3af Class 0). Both the USB and PoE connections can supply power independently.
Confirm the green LINK LED on the DANTE (PoE) port is lit, indicating a successful network connection.
On your computer, the DXA-USB-ED will appear as a standard USB audio device (no drivers required on Windows or macOS).
Open Dante® Controller on a computer on the same network. The DXA-USB-ED will appear as a Dante® device with transmit (Tx) and receive (Rx) audio channels.
Use Dante® Controller to route audio channels between the DXA-USB-ED and other Dante®-enabled devices on the network.
Verify audio is transmitting by checking that the yellow DATA LED on the DANTE (PoE) port blinks during active audio data transmission.

Cable Requirement — Important

For reliable Dante® network audio performance, use CAT6 or CAT6A Ethernet cables up to 328 ft (100m). A dedicated Gigabit Ethernet switch is recommended to avoid network congestion and clock sync issues. Ensure all Dante® devices on the network are set to the same sample rate.

Understanding Power Options

The DXA-USB-ED supports two power input methods:

USB Power (5V): The device draws power directly from the USB-B port connected to the host computer or USB power adapter. This is the simplest option when a PoE switch is not available.
Power over Ethernet (PoE): The device can also be powered through the Ethernet cable from a PoE-capable network switch (IEEE 802.3af Class 0). This is useful for installations where running a separate USB power cable is not practical.

Either power method can be used independently. You do not need to use both at the same time.

What Devices Is the DXA-USB-ED Compatible With?

The DXA-USB-ED is compatible with any computer or USB audio device that supports USB Audio Device Class v1.0 standards. No additional drivers are required on Windows or macOS for basic USB audio operation.

Compatible USB source devices include:

Windows PCs and laptops
macOS computers and MacBooks
USB audio interfaces and mixers with USB-B connectivity
Any device compliant with USB Audio Device Class v1.0

On the Dante® network side, the DXA-USB-ED is compatible with any Dante®-enabled device, including other ToVi Dante® models, Dante®-enabled mixers, amplifiers, speakers, encoders, and decoders.

Frequently Asked Questions

Q: What is the OREI DXA-USB-ED used for?

A: The DXA-USB-ED is a Dante® USB Transceiver that connects a USB audio device — such as a computer or laptop — to a professional Dante® audio-over-IP network, allowing audio to be routed to and from other Dante®-enabled devices.

Q: Does the DXA-USB-ED require drivers?

A: No. The device uses USB Audio Device Class standards and is recognized automatically by most Windows and macOS systems. No additional drivers are required for basic USB audio operation.

Q: How do I route audio to and from the device?

A: All Dante® audio routing is managed through the free Dante® Controller software. The DXA-USB-ED will appear in Dante® Controller as a transmitter and receiver, and its audio channels can be patched to and from other Dante®-enabled devices on the same network.

Q: Can I power the device without a PoE switch?

A: Yes. The device can be powered directly from the USB-B port connected to your computer or a USB power adapter (5V). A PoE switch is not required if USB power is available.

Q: What sample rates does the DXA-USB-ED support?

A: The device supports 44.1 kHz, 48 kHz, and 96 kHz at 24-bit depth. All Dante® devices on the same network should be set to the same sample rate to avoid audio issues.

Q: What does the green LINK LED indicate?

A: The green LINK LED on the DANTE (PoE) port remains steady when the network connection is established successfully. The yellow DATA LED blinks during active Dante® audio data transmission.

Q: The device does not appear in Dante® Controller — what should I check?

A: First, confirm the device is powered (via USB or PoE). Then make sure your computer and the DXA-USB-ED are on the same network subnet. Also check that firewalls on your computer are not blocking network discovery for the Dante® Controller application.

Q: Why is audio distorted or not playing correctly?

A: Confirm that all Dante® devices on the network are set to the same sample rate. Check for clock synchronization issues in Dante® Controller. Also avoid network congestion by using a dedicated Gigabit Ethernet switch rather than a shared general-purpose network.
