1.A17CSII is a gallstone hybrid power amplifier with digital fiber coaxial and wireless Bluetooth input.
2. The audio signal amplifying circuit in the machine is the common cathode amplifier and buffer amplifier of the electron tube. The used electron tube is a 12AX7LPS/12AU7 made in Russia. The sound performance is better than that of the domestically produced 12AX7/12AU7 used in the A17, and the bile taste is more intense. Better air quality.
3. The use of electronic tube and field-effect transistor and IC hybrid precision high voltage power supply, the tone performance is not only more bile, but also very high voltage stability, AC ripple coefficient is very low, than the pure transistor high voltage power supply The benefits of timbres are even more pronounced.
4. The voltage gain stage of the transistor power amplifier part is cascoded by the FET; Class A current amplification adopts the Toshiba brand power tube, and the tone performance is thicker and warmer; the output power is increased to 150W (8Ω) specifications. Sound density and great dynamic performance make it easy to drive a variety of high-end branded speakers.
5. The cross-connected and uninterrupted capacitor for the electronic tube circuit is the German WIMA brand MKP series advanced audio capacitor. The filter capacitor used in the power amplifier of the transistor is the Japanese 10,000uf/80v specification for the FORAUDIO series of the ELNA brand. It has excellent performance in both the tone and the sound field. It plays an important role in improving the sound quality and timbre of the whole machine.
6. The signal input and output cables used in the machine are all American-made XLO advanced signal lines, making the performance of the timbre even more icing on the cake.
7. Adopt Japan's ALPS large remote volume potentiometer; it has reliable and durable, low noise, no sound, small error between the two channels.
8. The output can be easily connected to any speaker cable with a large gold-plated binding post, and a two-wire split-tone connection can be used to achieve ideal transmission of high and low audio currents.
9. Aluminum alloy multi-function infrared remote control, make the operation feel better and more stylish.
