Make your home cinema set's speakers wireless.
No more messy cables in your room; the Surround Anywhere 221 enables you to connect your home cinema set's (rear) speakers wirelessly.
Transmitter and receiverThe Surround Anywhere 221 consists of a transmitter and a receiver. These connect to your home cinema set and your speakers, respectively.
Digital transmissionThe Surround Anywhere 221 ensures digital transmission, resulting in better than cd-quality sound. Additionally, the enhanced 2.4GHz technology prevents interference with your existing Wi-Fi equipment, and it allows multiple sets to be used in the same room. This enables you to make both your front and rear speakers wireless!

The uncompressed digital link provides better than CD-quality sound, without interference or delay.
Improved 2.4 GHz technology prevents interference with your existing Wi-Fi equipment, making them work perfectly side-by-side in the same area.
Transmitter and receiver are paired (secure pairing), enabling you to use multiple sets in the same area (6 max).
The receiver's built-in amplifier provides plenty of power for your rear speakers.
Because of the direct connection to your surround set’s speaker output, the speaker volume will automatically correspond to the surround set’s volume.
Volume control on the receiver ensures the right balance between front and rear speakers.
