Description ?Condition?UsedThe A-9150 integrated amplifier incorporates musical instrument tuning know-how.The NOVUS NV10 is a hybrid piano created by Kawai Musical Instruments Manufacturing Co., Ltd., using 90 years of musical instrument manufacturing know-how. The NOVUS NV10 incorporates Onkyos 70 years of know-how as an audio manufacturer. The A-9150 (S) is an integrated amplifier created through sound quality tuning that takes advantage of the experience gained through collaboration across industry boundaries. The sound perfectly reproduces the timbre, reverberation, and lingering sound of instruments, thereby once again offering the true meaning of audio equipment, which is enjoying music. Joint development of a concept model In the spring of 2016, the electronic piano concept model CS-X1 was exhibited at the Frankfurt Music Messe 2016, an instrument show held in Germany. From there, the collaboration between KAWAI and Onkyo began. The CS-X1 was set with the very high goal of reproducing the sound of KAWAIs highest-level concert grand piano, SK-EX, on an electronic piano, and professionals in both musical instrument and audio fields worked hard to develop the housing and electronics. We approached this from both sides of the circuit. Collaboration for commercialization Unlike traditional tuning, which is designed for use in a home listening room, checking the sound of KAWAI, a traditional musical instrument manufacturer, is a very difficult task because it is designed for performances in concert halls and other venues. did. In order to overcome the high hurdles of reproducing a vast sound stage and power reminiscent of a grand piano, and a transparency close to that of a live performance, we repeated trial and error on the component layout and wiring patterning of Discreate SpectraModule and DIDRC filter. We will continue to evolve. Newly developed Discrete SpectraModule that achieves high-end class dynamic characteristics A discrete configuration amplifier module that achieved a slew rate of over 500V/?sec and flat linearity up to the megahertz band, born from the Onkyo R&D teams long-term pursuit of dynamic characteristics. Discrete SpectraModule is installed in the amplification stage of the main amplifier. In addition to a clear sound field and a fresh sound image, it realistically reproduces the nuances of the performance, the tone of the instrument, the resonance, and the lingering sound, conveying the passion contained in the sound source. Discreate SpectraModule has been highly evaluated for its ability to reproduce the natural tones typical of a grand piano, and has been adopted by Kawai Musical Instruments Manufacturing Co., Ltd. (KAWAI)s hybrid piano NOVUS NV10. * * The Discrete SpectraModule installed in the A-9150 has been further customized for audio use by incorporating the musical instrument know-how gained when adopting the NOVUS NV10. Carefully designed housing structure including a 1.6mm thick flat chassis In order to suppress high-frequency vibrations that adversely affect sound quality, a flat chassis with no unevenness is used. It uses a 1.6mm thick steel plate to ensure extremely high rigidity. By choosing aluminum material with excellent vibration damping properties for the front panel and volume knob, we are working to eliminate coloration that could not be eliminated by improving the electrical circuit alone, reproducing purer tones. Furthermore, the strength around the volume knob is strengthened to suppress unnecessary vibrations and achieve clear sound quality. Strengthening the power supply improves power linearity and provides stable music playback.The power amplifier section uses reinforced transformer windings, bus bars, etc. to strengthen the power supply and improve power linearity against constantly changing speaker impedance. Achieves high drive power. The power supply section is equipped with a large capacity EI type transformer and two custom designed 10,000?F electrolytic capacitors. By connecting the power supply capacitor to the power transistor with a copper bus plate, a low impedance and powerful power supply circuit is realized. In addition, a large extruded aluminum heatsink is used that has a large heat capacity and is resistant to thermal changes. We have also thoroughly addressed heat dissipation, which is essential for stable operation. These commitments have resulted in high-level speaker drive capabilities that create a stable operating environment and reproduce even the finest nuances of musical information. Equipped with a DIDRC filter that reduces noise outside the audible band In the ultra-high frequency band that cannot be heard by the human ear, there are signal components caused by digital devices such as clock signals. When distortion occurs in that band, a phenomenon called beat occurs, which generates noise that is harmful to the auditory sense and has a negative impact on the original timbre of the sound source. Onkyo investigated the beat generation mechanism that causes this noise and developed DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry). We succeeded in suppressing the noise level to below -140dB, which is far lower than the limit of human hearing (approximately -120dB). A-9150 has this DIDRC filter installed after the DAC. It realizes smooth and rich music playback, free from the noise peculiar to digital sound sources that leads to the hardness and digital smell of the sound. ?We take the utmost care in packaging!
