Spec:
1. equipped with BISA current indicator and external BI1, using imported Z11 core pole level isolation cattle and imported EI core high performance broadband output cattle; Using the United States 12AWG single and multi-strand fever wire connection, the extreme isolation cattle effectively alleviate the impact of the current, so that the low-frequency spring power, control power is enhanced, the knot power is richer. The material used in the machine is 100% original imported customized components.
2. 5 AR4 real bile rectifier design, balance tube life, bile flavor, unique double high voltage circuit.
3. 12 AX7 high gain front stage tube, is 100 times the gain coefficient of ordinary 6N3, 6N8, etc., the sound is more vivid and fresh.
4. four KT88 tube after the push, high pressure, sound full and calm, momentum sharp, open Yang delicate, low frequency is unusually strong and powerful, cope with symphony and other large food speakers easily.
AS ADJ adjustment function, easy to monitor the power tube working state and adjustment; Dual function level meter display, the hands swing with music, dynamic.
5. with MM head amplification, convenient for you to appreciate LP simulation original sound, with the merging machine \ pure after the random switch function, force water full, senior players have to play.
The output of the headset directly has the output of the cow, and the sound quality is benefited from the unique core technology of the X7 output cow, which is beyond the reach of the ordinary independent ear amp.
If X5 breeds EL34 characteristic roundness, fine, analytical power, delicate and elegant;
X7 shows a KT88 output structure amplifier valuable atmosphere, full, sweet, open Yang, power
The machine features
1. pure manual production, the whole machine adopts shack welding
2. adopt two high quality wide frequency response high sound quality Japanese EI type output transformers
3. Use high-power Z11 iron core ring type power transformer specially designed for this machine
4. voltage amplification and push stage using 5AR4 as bile rectifier power supply..
5. Use 12AX7 and 12AU7 vacuum tubes for voltage amplification and phase reversal, and use KT88 vacuum tubes for AB1 push-pull power amplification; Provide triode and superlinear selection function: triode working mode, sound soft, pure and smooth, suitable for the appreciation of human voice, string music and other types of music; Super linear working mode, sound open Yang, bold and unrestrained, good momentum, suitable for enjoying the big scene, big dynamic and other types of music.
6. peripheral power tube current adjustment button and current display head
7. with pure after function, can be connected to independent before signal input
8.with the function of sing and play, can be connected to the vinyl record player
9. infrared function remote control
10. Mute delay function (about 30 seconds)
11. ALPS motor potentiometer in Japan was used
12. easy to install plug type vacuum tube protective cover
