Dante AVIO USB-C
Bridge a computer’s USB audio to a Dante network for playback, recording or a remote call.
Need this equipment for your project?
Tell us how the computer needs to connect to the Dante network and which applications you plan to use. GLMedia can review rental or purchase options and help plan the audio path. Start with a diagram or connection photos, even if some equipment is still to be decided.
Model and application
- Model
- ADP-USBC-AU-2X2
- Audio
- 2 inputs / 2 outputs
- Sample rate
- 48 kHz
- Resolution
- 24 bit
- Power
- Class 1 IEEE 802.3af PoE or USB power from a suitable host
Confirm the USB-C adapter, not AVIO analog, AES3 or Bluetooth. It is an audio interface, not an Ethernet internet adapter or a complete conferencing DSP.
Connections and required equipment
Playback: application → USB output → AVIO Dante transmit → network receiver. Recording/call send: console Dante transmit → AVIO receive → USB input. Configure both subscriptions and the application device; they are separate directions.
Prepare the system
- Record part number, host OS, firmware and the intended send/return map.
- Connect approved network/power and confirm device synchronization before routing at the supported sample rate.
- Select AVIO as the application microphone/speaker where required; test both directions with protected levels.
Questions and troubleshooting
Case: Dante Controller sees AVIO, but laptop playback is silent.
Network discovery does not select the computer’s playback device.
- Check the application and OS output device, volume and mute.
- Follow AVIO transmit subscription to the intended destination; then check its input patch and meter.
- Play a known file at a controlled level and check the destination meter. If selecting AVIO produces a signal, check which output the application was using. If AVIO transmits but no signal reaches the destination, follow the subscription and input patch. If the issue remains, record the OS, application and subscriptions for support.
Case: the remote guest hears themselves.
The USB bridge does not create a mix-minus by itself.
- Trace the call return separately from the console send into AVIO.
- Exclude that same return from its send bus and test with headphones before opening the room PA.
- If the send retains local speech and excludes the guest’s return, check the result on an actual call with a remote listener. If echo persists, review acoustic pickup and duplicate application or loopback paths with the audio operator instead of changing USB gain.
Case: USB power works, but an update fails.
The USB-C port can power the adapter during normal use. Updating requires PoE because the AVIO’s USB-C power-delivery circuit resets during the process.
- Identify the exact USB-C unit and use standards-compliant PoE for the documented update procedure.
- Do not interrupt a running update or repeat resets blindly; record the error and use official recovery/support guidance.
- Once the maintenance update completes successfully, check the reported firmware and both playback and recording routes before returning the system to use. If the update or recognition still fails with the required power arrangement, retain the exact error and power-source details for Audinate support; do not improvise a recovery procedure.
Choose the next check
| Observation | Next check | What to record |
|---|---|---|
| Playback absent | OS/app output plus Dante transmit | Device and subscription |
| Recording/call input absent | Dante receive plus app microphone | Bus and device selection |
| Power/update issue | PoE standard and update procedure | Injector, host, firmware and error |
Precautions
- Do not use an unidentified passive injector as a substitute for documented PoE.
- USB-C connector shape does not guarantee host compatibility or unlimited charging power.
- Schedule firmware changes outside operation; preserve working routing and avoid duplicate computer loopback.
