The maturity and success of a product requires time and the joint efforts of countless people. The successful development of HP's Siqi power amplifier proves this point. At present, most domestic brand power amplifiers on the market have a technical gap that is difficult to overcome in a short time compared with foreign famous brand power amplifiers. In order to meet the competitive needs of the market and the psychological needs of consumers, some common big brands in the market have or are currently cooperating with foreign brands and institutions. These cooperations have indeed provided some successful and useful help for their market operations.
It was in this market climate and environment that HP boldly attempted a joint venture with Australia's Whatmough Company, making full use of HP Audio's world-renowned HI-Fi speaker manufacturing technology and Whatmough Company, which is well-known in the European and American audio industry. A beautiful rebirth of electroacoustic technology in praise. Siqi amplifier AI-50 is the result of this cooperation.
As the first color screen power amplifier with dynamic matrix fluorescent display in China, its birth officially announced the advent of the era of color screen display in power amplifiers. Its color screen function gives people a strong visual impact, breaking the monochromatic display world dominance and giving the power amplifier a brand new look.
AI-50’s entire machine panel is made of space technology magnesium aluminum alloy wire drawing material and is precision processed by CNC. It is equipped with Japan’s NORITAKE super large round high-density radiation-proof color display and imported high-density alloy buttons. , continuing the tradition of simple and clear panels of Siqi, giving people a simple, novel and fashionable feeling.
As the latest product in the Siqi series, AI-50 has a high technical content. As the latest 6-channel AV amplifier, it has 6-channel independent power amplification. In addition to supporting the latest and most top-notch audio formats such as DTS ES and DOLBY DIGITAL EX, it is also compatible with all other audio formats on the market. The power amplifier adopts a large dynamic, high current, high slew rate, wide frequency response design, and the ultra-high sound quality multi-channel fully meets the requirements of SACD and DVD-AUDIO.
This machine adopts fully humanized operation. The panel buttons adopt a touch-type design, which not only improves its durability but also makes the operation easier; the display screen adopts a full Chinese layered menu, all operations are clear at a glance, and the user can perform correct operations according to the display without even looking at the manual. operate. This machine also introduces an environmentally friendly volume design to prevent the user from affecting human hearing and the service life of the amplifier due to the previous too loud volume when turning on the phone. Of course, it can also effectively protect the speaker.
The materials used inside this machine can also be described as well-intentioned. The whole machine adopts a fully separated high-strength intensive structure and independent circuit design to prevent mutual interference between lines to the greatest extent. The additional shielding design is supplemented to completely exclude the electromagnetic waves generated during use and avoid the impact of electromagnetic waves on the effect. . Toshiba's 2SA1943 high-power amplifier tube has a maximum undistorted continuous output power of 120W per channel under a load of 8°, meeting the discerning requirements of audiophiles for music intensity performance. The independent power supply system of multiple power supplies makes it more stable under long-term working conditions, and also reflects the manufacturer's high specification requirements for this amplifier in order to achieve the HI-FI standard. In particular, it should be mentioned that the amplifier has a built-in 16-bit high-speed microcomputer CPU chip, which can control the operating system and effectively control signal changes at a speed of processing 5,000,000 instructions per second, making the user's operation more convenient and the listening effect more ideal. . Coupled with its multi-channel interfaces (including DTS ES, DD EX) designed to meet the latest home theater technology requirements, you can keep pace with the latest audio-visual trends. In addition, if a certain function of the power amplifier is in use, other functions will automatically enter the sleep state, truly ensuring the complete independent operation of the three major functions of viewing, listening and singing, so that the viewing, listening and singing synchronization can meet the requirements of high-standard effects.
When listening to the clip of "Thunder Rescue" recorded using the latest 6.1 technology, a huge wave hit the face, strings of water droplets flowed down from the soldiers' helmets, and bits of gunshots roared from the ears. However, it all makes people feel the chilling reality of being on the battlefield. Coupled with the AI-50 full-band equal power output, the entire battlefield is presented in three dimensions in front of the listener. Let's listen to the highlights from another blockbuster movie "Dragon Slayer": the thick midrange of the dragon, the flapping of the wings of the flying dragon flying around the head, and the different textures of the horse and the flying dragon stepping on the grass, all of which reflect the details of the AI-50 Home theater capabilities such as true restoration and continuous positioning. Let's listen to the concert suite "Butterflies in Love with Flowers" by the famous Chinese composer Chen Qigang. The female voice in the song is deep and delicate, melody, euphemistic and lingering. It completely integrates the charm, sexiness and vitality of oriental beauties into the music, making every listener enjoy the process. , all felt the trembling of their hearts. Throughout the performance of the piece, the orchestra's different instruments were accurately positioned, and the scene was vast, giving the audience a sense of immersion.
Karaoke is indispensable for Chinese people to use home audio. Therefore, Siqi AI-50 amplifier also has a fully digital multi-function karaoke system. This machine uses Mitsubishi M65831 top chip, which can repair the defects of different voices. Carefully adjust each frequency band of the voice, and then combine delay and reverberation effects according to the different styles of the songs, so that the human voice can be optimally modified and adjusted to achieve the best singing effect and allow the singer to get the best performance. Feel like a professional singer.
As the representative of the latest generation of Siqi power amplifiers, the AI-50 power amplifier has experienced the development and training of the 70, 60 and other series, and is generally more mature. In addition, the technology development process breaks the limitations of domestic technology. The entire development process is fully synchronized with Whatmough Company over the network, so it draws on the strengths of both parties. In addition to retaining the traditional simple and professional appearance design of Siqi amplifiers, this machine's internal technical structure, material matching, etc. are completely developed and designed by European and American electroacoustic experts from Whatmough Company. It is believed to have strong competitiveness in the market.
