NFC offers an extremely simple setup. Android Beam software uses NFC to complete the steps of enabling, pairing and establishing a Bluetooth connection. Simply tap your NFC enabled device on this unit and you are paired. 
 
Simply pair your Bluetooth enabled device–such as your smart phone, iPad, Android tablet and connect to your AV receiver, multimedia speakers and more with this bluebooth receiver. With the inclusion of the highly renowned apt-X codec, this receiver allows you to enjoy wireless Bluetooth audio quality indistinguishable from wired, with an impressive dynamic range. Featuring a high-quality DAC that helps clean up poor audio that is often found in downloaded music and videos. Also SBC compatible for other Bluetooth devices using the A2DP standard. 
 
The receiver outputs audio through both analogue and digital outputs simultaneously! Not only does this make it great for hooking up to your high-end amplifier or receiver using the high quality digital link, but you can also plug in another pair of powered speakers at the same time! This allows you to listen through either system without the need to connect to another Bluetooth device! 
 
A Signal-to-Noise Ratio (SNR) of more than 100dB, in combination with 2Vrms output at maximum volume means the receiver can not only compensate for low volume sources, but gives you a wider range of control from your mobile device without losing audio quality or increased background hiss you get from other devices on the market! Basically keep the volume on your amp or speakers low for reduced noise, and control the audio level directly from your phone or tablet—perfect for audiophiles!
