The sound is grand and magnificent, open and wide; performance of each frequency point perfect! In particular, when the use of imported tube like as RCA6080 (Default as Beijing 6N5P tube), more delicate high-frequency, low frequency more powerful!
The greatest feature of Bluetooth audio decoder or Bluetooth audio amplifier is that give up traditional wired connection, use Bluetooth technology to connect mobile phones, tablet and other electronic terminals with them.
This speaker completely overthrew the concept of speaker-making, speaker adopted Labyrinth cabinet structure that will get well effect but the structure is more complex, limiting its development. Through we continuous the efforts, we make a revolutionary new speaker for 2 inch full range speaker.

Natural, warm and soft sound from this perfect matched, it is very convenient to play lossless music songs from the music player like as HIFI music app of your Bluetooth emabled devices.Natural, warm and soft sound from this perfect matched, it is very convenient to play lossless music songs from the music player like as HIFI music app of your Bluetooth emabled devices.
It is connected with the main speaker through smartphone, and then the main speakers connect s with the slave speaker via a Bluetooth wireless mode connection, to achieve true wireless Bluetooth for left and right channels separated of Bluetooth speaker.The program based on CSR Bluetooth4.0 with dual-mode module development. When not connected to the speaker, the main speaker stereo back monomers. It is no delay, and good sound quality. Designed to provide customers with stable performance characteristics of high-end Bluetooth loud speaker programs. It need 2 pcs Bluetooth modules with TWS function to realize it as below.
For tube amplifier with parallel connected by 2 pcs 6P1 tubes, the internal resistance of output transformer will be reduced by half, and more control power to speaker, output power increased as double.
And there is one type preamplifier, we call it as tube buffer that is no gain, input and output signals 1 to 1, 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

Output transformer used in HIFI tube amplifier is a key component in high-fidelity audio equipment, it utilizes electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core. In electrical equipment and radio field, commonly used as lifting voltage, matching impedance, safety isolation and so on.
It is a finished tube FM tuner, whose tubes have been located on the same board, so it looks compact and elegant, and it is a little different with the tube FM radio that we have post before.

Hundreds of preset stations available, you can listen radio worldwide from it.
Listen to the sound is far wider sound field, better resolution, better layer structured. We are intoxicated by the music, the melody of each neuron start wondered if peristalsis, high, medium and low frequency is very balance, so fantastic! The sound of the human voice is warm, soft and pure, and natural loose, smaller noise pollution, rich musical taste, great flavor, also has a good low-frequency performance, is a treat for the ears, very enjoyable for long time listening and you don’t feel tired.
DAB is the third generation broadcasting after conventional AM, FM analog broadcasting .DAB is short for Digital Audio Broadcasting, which is close to CD quality sound, and the listener can listen to the radio non-interference completely.
The tube FM radio used tube 6N3 as a high-level and mixing, tube 6C11 as the unit local oscillates,tube 6J4 as IF amplification together with 5pcs mid cycle inductances, and it has the advantages of high sensitivity, low noise. After stereo decoded by TA7343AP, then the signal will be amplified by tube 6N2 as a preamplifier. And power amplifier part, it used 6N2 to drive 2pcs tube 6P1 that is classic and famous application.
This tube radio has two tubes, which adopt super-regenerative mode to receive FM radio signals. Has high sensitivity, Either high impedance headphones with nostalgia, but also through the line output jack. You may connect it to amplifier and computer sound card to access the playback, that expand the scope of application of the radio.
This tube FM radio head adopted tube 6C11, and its rectifier adopted tube 6Z4. Its signal reception and treatment adopted classical tube circuit, and used TA7343 as a stereo decoder that then result in stereo output. After stereo FM signal input power amplifier system for amplification, you will listen to FM radio with musical tube sound
Gennally, a HIFI interconnection RCA cable is made of 2 pcs pure copper RCA connecters which are made of copper-plated plug generally, copper shell, and advantages of copper shell can be shielded from external interference and a pair separated OFC wires cable instead of a pair of wires molded together, and then assemble them though soldering with high quality solder.
Tube amplifer combines wireless Bluetooth technology is new trend, especially, combines the latest Bluetooth 4.2 like as CSRA64215 that also supports aptX audio technology that provides CD-level sound quality with Bluetooth connectivity
