1, Yamaha dongle:
Yama dongle has superior performance, advanced technology and guaranteed product quality. Yamaha's products range from keyboard instruments such as piano, electronic organ and synthesizer, wind instruments such as brass and woodwind, stringed instruments such as violin and cello, and all percussion instruments to the most advanced professional audio equipment. Yamaha is the largest musical instrument manufacturer in the world. ?
2, marantz dongle:
Marantz dongle has comprehensive functions, and users can switch back and forth between various functions, making it more convenient to use. Marantz efficacy machine is rich in music sense, advanced in technology and ultra-high-definition. Marantz wireless power amplifier achieves better sound quality by selecting components and modifying the design.
In addition, there is a KI signature edition, which is a special edition signed and sold in the name of marantz's current chief designer Ken Ishiwata. Marantz audio with KI has been strictly screened and carefully arranged by Ken Ishiwata from components to the whole machine structure, which means that uncompromising Hi-Fi playback is much better than ordinary models without KI signature.
3. Sony dongle:
Sony dongle is the first choice for many users because of its simple structure and novel design. In 1950s, Sony's black-and-white TV sold well, but its technical competitiveness was not outstanding, and the quality control of color TV products manufactured afterwards was not satisfactory, which led to huge losses and pushed the company to the brink of bankruptcy.
1967, Sony released Teletron CRT technology developed by Masaru Ibuka himself, which made Sony TV sell well all over the world, and the huge development debt borrowed by Akio Morita from the Japanese Development Bank was paid off within three years. It has become the dominant standard in the field of professional broadcast video, and many broadcast video standards are based on this.
4. Wireless dongle:
Pioneer dongle has advanced technology and many breakthroughs in function. The company's business scope includes the manufacture of musical instruments, musical instrument accessories, wooden handicrafts and hardware accessories.
Technically, the encryption dog format is far stronger than other formats, but Panasonic has won the support of many manufacturers through flexible authorized operation, thus dominating the civilian market. With its technical advantages, wireless power amplifier format has entered the professional field and become the dominant standard in the field of professional broadcasting and video. Today, many broadcast video standards are based on this.
5. Harman Kardon dongle:
Harman Kardon dongle is easy to use and has no complicated structural design. The tuner, the component control unit and the speaker are integrated into a whole. Harman Kardon wireless power amplifier sells the world's first stereo receiver, once again aims at non-technical users, and strives to make high fidelity more widely adopted.
Harman Kardon dongle implements encryption by exchanging data with encryption locks during software execution. The encryption lock has built-in single chip microcomputer circuit, which makes the encryption lock have the processing ability of judgment and analysis and enhances the ability of active anti-decryption.
This kind of encryption product is called intelligent password lock. The built-in microcontroller of the encryption lock contains algorithm software dedicated to encryption. After the software is written into the microcontroller, it can't be read out. In this way, it is ensured that the encryption lock hardware cannot be copied. Meanwhile, the encryption algorithm is unpredictable and irreversible.
With the development of decryption technology, the single-chip encryption dog is gradually being eliminated by the market because of its simple algorithm, small storage space and easy to be copied by hardware. Domestic encryption dog manufacturers have developed the fourth generation encryption dog with better stability, larger storage space and effective prevention of hard cloning.
