The main features of A30 are:
① The output transformer of the traditional bile duct machine is canceled and the power semiconductor transistor is used to replace the output transformer. The advantage is that various additional distortions caused by the traditional output transformer, such as frequency, phase, transient, square wave distortion, are completely eliminated, so that the frequency response range of the A30 can reach 10Hz-60kHz ± 1dB, and the output power can reach 200W/8 Ω, which is far beyond the output power of the traditional KT88 bile duct machine (within 100W), It is easy to drive low efficiency speakers, and it can also control large floor speakers with high efficiency.
② The success rate output stage is composed of 8 Toshiba high-power transistors, which can also be switched to 4 transistors through the panel switch for damping coefficient adjustment, facilitating the matching requirements of speakers with different sensitivity. The same panel switch can switch the bias voltage of AB1 (Class A) or AB2 (Class A and B) to obtain different timbres.
③ Mr. He confidently emphasized that the A30 uses all domestic electronic tubes. The front end uses ECC83 (12AX7) double triode for input amplification, 6N11 electronic tubes for secondary voltage amplification, and KT88/6550/EL34 and other electronic tubes with the same pin can be replaced at will. They are responsible for Class A driving circuits, making the A30 have a beautiful voice performance of traditional courage machines.
④ Advanced components dedicated to audio are widely used in the machine, such as the MKP film electrodeless capacitor dedicated to audio from WIMA, the oil immersed aluminum foil electrodeless capacitor dedicated to audio from Mcap (tube interconnection), the high-precision low noise resistance, and the 10000uf/80V electrolytic capacitor dedicated to audio from ELNA from Japan, which have excellent performance in both timbre and sound field; It plays an important role in improving the sound quality and timbre of the whole machine.
⑤ The precision high-voltage stabilized voltage power supply with electronic tube and field effect tube can effectively reduce crosstalk to ensure large dynamic performance. The AC ripple coefficient is extremely low, and the voice performance is more "bold".
⑥ The Japanese ALPS large quadruple high-precision potentiometer is adopted, which has the characteristics of low noise, no sound pollution, and minimal error between two channels.
⑦ The additional function of equal loudness switch can improve the performance of high and low bass when the volume is low.
⑧ Bluetooth (5.0) digital audio connection can be made with mobile phones, laptops, tablets and other devices. You can also connect digital or analog audio with iPod, iPhone, iPad, CD, DVD, and TV HD cassette. It is equipped with optical fiber, coaxial, USB digital signal input interfaces, 24Bit/192kHz digital to analog conversion accuracy, supports DSD512 format, and a group of analog signal balance input terminals.
⑨ Aluminum alloy multi-function infrared advanced remote control, better and more fashionable.
⑩ Surprisingly high cost performance, the A30 is priced at 19888 yuan, with 20000 yuan available.
To put it simply, the A30 is a new generation of tube combined power amplifier with full function and built-in decoding chip without output transformer and extremely high output power. Sonya has launched many CD players, and is no stranger to digital lines. The CV-1HD pre stage launched this year also has built-in decoding lines. CV-1HD is the first time that Sonya has added the decoding function to the front level. The decoding ability keeps pace with the times and provides a variety of audio source inputs, which is convenient for young generation digital streaming media players to use. USB adopts the mainstream XMOS receiving scheme. The decoding chip is the top class ESS9038Q2M, which supports up to 32bit/384kHz PCM and DSD512 formats. The detailed parameters of the A30 have not been published yet. It is estimated that the decoding part should be similar to the CV-1HD pre stage, which is very cost-effective!
