It caused quite a stir when it hit market. Its role and advantages are, it can greatly reduce the digital taste and transistor sound when connected between VCD, CD, DVD, CD-ROM and other digital audio amplifier, so that the entire sound system has sweet natural tube taste. X10-D Music Fidelity, cleverly designed that output terminal with a deep negative feedback, reaches a high performance, distortion rate dropped to a surprising degree.


Its output terminal with a deep negative feedback, reaches a high performance, distortion rate dropped to a surprising degree. 

And, its designer took advantage of the feature of a very good linearity and working condition of tube 6N11 still when its screen voltage reduce to 50V.And when provide AC 12V low voltage power supply , and boost to ± 28V power supply , which can significantly prolong life and improve the signal to noise ratio of tube.

Also. adopt positive and negative DC power supply, eliminating the second stage amplification tube cathode resistor and capacitor, eliminating the negative impact brought by the cathode resistor and capacitor. And transistors can also be used, without using those expensive, bulky high-voltage components.

We do not know, three-proof functions so called waterproof, dustproof, shockproof begins gradually integrated into design of many phones since when, in order to accommodate their needs of outdoor sports or field travel, such as MOTO three-proof smartphone for waterproof, dustproof, shockproof. Features of three-proof of smart phone is very simple with a slight dustproof, shockproof, waterproof phones, mainly for young users who love outdoor sports or professional users with special needs. As its professional waterproof, dustproof and excellent anti-wrestling, anti-rolling performance, it is competence to endure those extremely bad weather conditions and application of special occasions. Wireless Bluetooth speaker seems to have followed the trend, the three-proof function portable has added in wireless Bluetooth speaker. Here is this kind of wireless Bluetooth speaker designed for outdoor sports for young users or users with special professional needs.
three-proof Portable Bluetooth Speaker for outdoor sports

It may be parity trouble that to take a wired connection to listen music at outdoors, this portable speaker with Bluetooth wireless connection adopt Bluetooth version 2.1,it can be used to connect with smart phones, tablets, and a stereo Bluetooth enabled digital devices to listen music, its application is more extensive. The wireless Bluetooth speakers adopt two units which designed for armored car specifically and the sound effect is very shocking. Meanwhile, it has been specially designed, equipped with internal damping and waterproof rubber, waterproof level reaches IPX5. According to IPX5 definition of Baidu Encyclopedia is defined as follows: it can be withstand water spray test without damage, use the 6.3mm diameter nozzle spout, make test samples be apart 2.5m ~ 3m from mouth water with 12. 5 L / min (750 L / h) of water flow speed, and testing time is at least 3 min according to sample shell’s surface area of per square meter of 1min (not including installation area); namely in the above experimental conditions, waterproof function of three-proof wireless Bluetooth speaker works fine to ensure that it does not leak.

There are hidden metal grids behind converters of wireless Bluetooth speaker. Because waterproof rubber connector of the side and back is covered by a thick layer of special material, not only can it withstand rain water also it work for some time even if it is completely soaked in water. Its external dimensions are 127mm × 83mm × 57mm, weighs is about 346 grams, adopt two same 3W speaker units and a passive subwoofer unit components; the back set up a 3.5 mm audio output hole, which is an interesting option, you can use a cable to connect two devices and use them as a stereo device or external stereo headphones, as the case of multiple speakers 3.5mm series to increase the volume. There is also a Micro-USB Interface (USB Adapter), for using with an external adapter or USB output interface device, and there is a charging and battery status indicator also.

It is powered by a 1400mAh internal rechargeable Li battery, and can provides 12 hours playback time after a full charge , also due to its built-in noise reduction microphone, thereby it provide speakerphone function, and call sound clarity.

Also there is similar products for Rainproof Dustproof Antiscratch Antishock Portable Bluetooth Speaker Bluetooth 2.1 Plus EDR Stereo Outdoor .

Sound of nature -- Wistao NFC Bluetooth 4.0 HIFI Bluetooth acoustics hit market, wireless HIFI come from here!


It has been used in high-end Bluetooth stereo that CSR's Bluetooth 4.0 chip with apt-x Professional codec technology widely, and become a trend in wireless HIFI acoustics. Recently, Wistao Technology released a pair of separated HIFI tube Bluetooth acoustics, and two HIFI Bluetooth speakers which based on CSR Bluetooth 4.0 technology and apt-x decoding all. For both Bluetooth speakers, one is a 2.0 channel stereo HIFI Bluetooth speakers, the other is an integrated desktop HIFI tube Bluetooth acoustics.

These HIFI Bluetooth acoustics are two-channel stereo output, adopt CSR Bluetooth 4.0 technology, and support CSR apt-x professional decoder. All cabinets of HIFI Bluetooth speaker is made of high quality MDF (medium density fiberboard); separated HIFI tube Bluetooth acoustics and integration Desktop HIFI tube Bluetooth stereo, whose preamplifier is made of tubes, and their out power are from 2 X 25W to 28W, fully to meet the demand for enjoying music indoor . Cabinet of speaker are designed and tuned by professional engineers and its circuit is completed to adjust by the UK experienced engineering team in order to make sure it more perfect sound quality, let you enjoy HIFI music. Overall feeling is, that surging tide of audio sound, powerful bass, treble highly resolving power, and human voice being rich sense of the scene, accurate sound field positioning, like a "good voice" singer standing in front of you…... In addition, all models above can be built-in NFC chip as an option, so you don’t need to open the Settings menu of smart mobile terminals, and can quickly achieve Bluetooth pairing, greatly enhancing users’ experience.

And if you download and install a lossless music formats player (such as WMA, AAC, FLCA, AIFF, etc.), it will achieve to reproduce HIFI music with a wireless way .Due to adopting Apt-x professional audio decoding technology, its performance will be strived for further improvement to compare with normal speaker, or even pull away, and easily to achieve CD-quality sound.

Main characteristics of CSR APTX audio codec technology is low-power, low-latency (when sampling frequency is 48 kHz, it is less 2 ms), fault tolerance (When BER <1:10,000 perfect to regenerate), high-quality, etc. Its high sound quality is main reflected in frequency response range of 20Hz-22kHz, supporting 16bit, 24bit audio, sampling frequency up to 48kHz, dynamic range in 16bit> 92dB, 24bit > 120dB, but sound basis of dynamic range is 96dB for minimum sample rate of 44.1kHz CD-quality of 16bit stereo (entry-level quantization bits). From comparison above data of apt-x, we can draw a conclusion that it is not difficult to see how it reach and exceed t CD quality. It can break through the barriers of bandwidth with Bluetooth connection to transmit excellent reproduction of stereo sound with CD-quality stereo audio. At the same time, CSR provide Clear Voice Capture (CVC ®) technology for high-end Bluetooth stereo acoustic echo and noise cancellation. (More specific features of apt-X audio decoding technology, please see "Bluetooth 4.0 version of the CSR series chip key features of" and "CSR Bluetooth 4.0 and apt-X high-fidelity audio technology").

Perhaps, these figures may sound so professional that you are boring, ok, let look at evaluation to apt-x from manufacturers such as Nokia, Samsung.
Nokia's evaluation it that apt-x audio codec technology of CSR can break through the barriers of bandwidth, with CD-quality stereo audio through a Bluetooth connection to a wide variety of consumer electronics applications Transfer ".
Samsung's evaluation is similar, CSR apt-x technology demonstrates superior stereo audio Bluetooth connection quality, and its completed audio frequency bandwidth consistent complies with high-fidelity performance.

What are you waiting for still? Why do not you work together with us to enjoy this fantastic wireless HIFI music!
