Wireless speaker connection. Send audio from your AV receiver or amplifier wirelessly to your surround speakers. Expand audio to multiple rooms (max. 3) in your home (multiroom). Digital audio technology ensures interference-free transmission and CD-quality sound. The transmitter and receiver are uniquely paired, allowing you to use multiple sets in the same room (max. 6). Automatic volume control through the AV receiver or amplifier and/or local control at the receiver. The volume control at the receiver ensures the right balance between the front and rear speakers. With this wireless speaker cable, you can connect the (rear) speakers of a surround set wirelessly. No more loose audio cables in your room. The Speaker Anywhere 650 guarantees digital transmission for high-resolution audio. The set can be expanded with up to two additional receivers (sold separately), allowing you to send audio to speakers in another room if desired. It is also possible to use an additional receiver to connect both speakers wirelessly to the AV receiver/amplifier without needing a cable between the two speakers. Use multiple sets in one room to make your front speakers wireless as well.
