With this handy USB dongle, you can wirelessly stream music from your computer to your Arcam rCube or rDac KW. And that's not just the music stored on your PC, either — it also streams any audio source your computer can access online. So you can enjoy Internet radio stations, PANDORA®, SlackerFM — you name it. If it plays through your computer's speakers, you can stream it to your Arcam device to enjoy with noticeably better sound quality.
The dongle plugs into a USB port on your computer, and has a transmission range of up to 160 feet. You can also plug it into the USB port on an rCube. Either way, the dongle can stream to up to four rCubes simultaneously.
From the review The Arcam rCube -- portable and powerful
"The rWave transmits whatever your computer plays. So I not only could play my digital library through the rCube, but also Internet radio stations... I could also broadcast to four rCubes from my computer with an rWave. I could see setting up a party music playlist on my PC, and filling the house with sound."
