Wireless transmitter

Bluetooth and Wi-Fi are the computer standards in wireless transmission.

But there are other means too.

Audioengine W3 Wireless Audio Adapter


16 bit / 48 kHz USB audio.


Audioengine D2

The D2 sends a 24bit/96KHz PCM stereo digital stream over-the-air in a "closed-system" Wi-Fi configuration. The system's proprietary RF technology ensures data integrity with no impact on existing routers or networks. The volume control on the D2 Sender is transmitted over an entirely separate channel so there is no impact on the digital audio stream.
