2.4 GHz wireless system, jack plug transmitter and receiver

What's the main difference between the previous B-2?<br>Narrower bandwidth (2Mb only) provides better anti-interference ability.<br>Lower power consumption, longer battery time. (7hrs working per charge.)<br>Auto Off: The TX will turn off automatically since there is no input signal for 10 minutes, then the RX will also turn off after another 10 minutes.<br><br>NUX B-2 PLUS<br>The NUX B-2 PLUS is a pocket-size 2.4GHz wireless system that offers guitar players an easy solution to go wireless. Step on the latest NUX wireless transmission algorithm, B-2 PLUS secures a better connection in a noisy RF environment. With the newly-added auto-off function, you'll never have to worry about leaving the system on and draining out the batteries.<br><br>HD audio quality,ultra-low latency & comparable operating range<br>NUX B-2 PLUS offers 24bit/44.1KHz high definition audio quality and has a comparable operating range of 60 feet(line-of-site) with less than 5ms of latency. <br>You can hardly find anything better within the same price range.<br><br>Improved connection stability<br>Products utilizing the 2.4GHz frequency band is everywhere nowadays; it's critical to find a way that can avoid most unwanted interference. Instead of increase the transmit power, we decided to narrow down the bandwidth to 2Mb so that B-2 PLUS can find the most available band. It's like driving a Motorcycle through a crowded highway.<br><br>Plug-and-play operation, 4 optional channels<br>Plug the transmitter into your guitar, plug the receiver into your amplifier or effect pedal; turn on both the transmitter and the receiver, and you're good to go. You can also take advantage of its four optional channels when gigging with your friends. <br>Up to four B-2 PLUS can be used at the same time in one space.<br><br>Guitar friendly, smart design<br>Plug the transmitter into your guitar, plug the receiver into your amplifier or effect pedal; turn on both the transmitter and the receiver, and you're good to go.
