This applies to the Audiohub 2x4
We always recommend using the mains power supply with Audiohub for optimum performance and to avoid unwanted audio artefacts. Optimal audio streaming performance and loud headphone levels cannot be guaranteed on all computers without the use of the included power supply.
It is possible to use Audiohub 2x4 with only USB bus power however you may find that the Audiohub has some limitations in this case:
- You will be unable to use the USB hub on the device.
- When using low impedance headphones with high output levels, it's possible to experience audio dropouts.
