The small device can take audio from any source with a USB port, headphone jack or stereo outs.
Whole home audio is a very cool setup, but it's not something that most people can spring for right out of the gate (especially these days!). The problem is that many wireless audio systems require that you buy into the product line, replacing your existing gear.
The Home Audio Link wireless adapter allows you to take your audio signal from anywhere in the house and send it anywhere else in the house wirelessly. You'll get 16-bit/48kHz uncompressed audio to the speaker, and you can even hook up multiple sound systems and switch between which one gets the audio.
You have a variety of ways to connect the adapter so you can hook up virtually every device you have. With USB you can attach a computer and a headphone plug will allow you to hook up MP3 players or anything else with a jack. Finally, stereo RCA cables are perfect for attaching a wireless subwoofer.
The new Aperion Zona HAL will run $149 for the full system and $70 for additional receivers.
