About the Harman Kardon Adapt

Add Bluetooth® and Wi-Fi® to your stereo

The Harman Kardon Adapt lets you add wireless music playback to your existing stereo or home theater system. It can also stream music to Harman Kardon Omni wireless speakers.
Add Bluetooth® and Wi-Fi® to your stereo
If you've got a killer home theater system that's missing wireless music streaming, there's a simple fix: the Harman Kardon Adapt. This compact device adds Bluetooth and Wi-Fi to your existing stereo or home theater setup, so you can stream music wirelessly with your smartphone or tablet. Just connect it to your receiver or amp, plug in the power cord, download the free app, and you'll open up a whole new world of music choices in your home theater.
Music throughout your home
The Adapt isn't just about adding more music to your current system. It can also link up with Harman Kardon's Omni speakers, to create a whole-home music system. Add an Omni 10 to your kitchen so you can keep listening while you grab a snack. Or play a different song in each room.
Easy wireless setup and operation
The Adapt works with your existing home Wi-Fi network, so it's easy to set up in just a few minutes. Once you're connected, you can stream music wirelessly using your smartphone or tablet. Send tunes to your stereo system and to Harman Kardon Omni speakers throughout your home. You can even stream 24-bit/96kHz high-resolution music for better-than-CD sound.

The compact Adapt offers Bluetooth and Wi-Fi connectivity for wireless music listening.
Stream audio from any app with Bluetooth®
In addition to Wi-Fi connectivity, the Adapt offers Bluetooth, which lets you stream audio from any app on your phone or tablet. Any song you can play on your device can be played wirelessly through your stereo using this compact adapter. Have apps for Spotify®, Pandora®, Google Play, and other music services? Stream them all via Bluetooth, with no restrictions. You can even stream from YouTube™ or audio from a video game — there are practically no limits. You can also send that Bluetooth stream to other Harman Kardon Omni speakers and components.
Easy control with your phone or tablet
Your smartphone or tablet isn't just your music source — it's also the remote. Download the free Harman Kardon Controller app to your Apple or Android device. Then, you can choose songs stored on your device, control music playback and volume, and group compatible HK speakers and components together for playing in multiple rooms. The app's colorful, intuitive interface makes multi-room music easy and enjoyable.
Add music to another room... without touching your smartphone
On the top of the Adapt, there's a large button with a slash. That's the "Link" button, and it offers some very cool features. Let's say you're listening to music in the kitchen on an Omni 10 speaker. As you move into the living room, you want the music to follow you. Simply press the Link button on the Adapt, and your stereo system will pick up the same music stream in perfect synchronization. Press and hold the Link button to engage party mode, so the same song plays on your entire Harman Kardon system of products.
