Yamaha power amplifier RX-V4600 research and development story6

indeed so. In order to realize this sound, what means in fact uses?in mountain: First strengthens the power unit largely, although is the same in the specification and RX-V2500, the peak power output is 180W x 7, but to realize “powerfully”, we increase the power transformer. Thus, may curl on a thicker line, the electric capacity also from 15000μF increases 18000μF, has realized the low impedance. Certainly is not only the capacity, the power transformer, the electric capacity uses after the RX-V4600 special-purpose tuning the part, the transformer uses 1 body packing structure the EI transformer, the electric capacity uses Carbon Sheath. Moreover, the independent volume line which installs through the transformer in carries on to the HDMI, i.LINK power supply, not because the function will increase gives other parts to bring the influence. the -- tone circuit also has the large part replacement?in mountain: Yes. Finally, compares with RX-V2500, unit replacement 120. -- has replaced a time part, will also trade?in mountain: In fact is each part trades while the audition, after having traded, returns process which is unceasingly redundant. Horn wire, RCA line, power line, if replaces, the sound will change, this will be everybody found that but the product internal part, as a result of the material quality, the structure, the factory to the sound strategy's difference, will have the inherent sound characteristic. If the product uses specific part constitution, has decided on the whole the power amplifier sound, also has the fixed characteristic. RX-V4600 increases the use the acoustic fidelity part is aims at reappears the musical instrument, the sounds of people and so on various timbres chooses. -- so that's how it is. You bring a part of this use the part, originally has these many types. The careful observation, the capacity electric capacity, the impedance, the different brand has many kinds similarly.in mountain: Yes. In tens of thousands kind of combinations, selects to this part most appropriate part is very important. Therefore this time to display “powerful” and “slender” the concept, main circuit's electric capacity which starts from the DSP foundation plate, uses needs the pressure resistance above part. Actual need 6.3V or the 16V pressure resistance's place, we use 100V. Because the high pressure resistance's part the material quality is quite good, can send out has the ample force, and is stable sound.in -- Mr. Shan knew very well that each part's sound, changes likely the magic resembles does a combination, makes RX-V4600 the sound.in mountain: It is not this. Because has period of time not to be engaged in the acoustic fidelity acting, now part's sound has had the very big change. For instance uses massively the electrolysis electric capacity's drive pipe, turns PET from 塩 the resin. The part post, foundation plate's galvanization also turned the tin from the lead + tin
