Fiber coaxial USB DAC decoding amp machine
- using the original AD1955 + WM8805 + PCM2706 + (AD827 disassemble)
- electrolytic capacitor signal main circuit using Taiwan famous brand, the main filter capacitor using BC dedicated electrolytic capacitor capacity 2 2200UF, most of the capacitor using solid-state imported capacitors,
rectifier full-wave bridge rectifier circuit to ensure a strong stream of continuous power support.
-potentiometer using Japan original ALPS potentiometer potentiometer.
- The machine is made of aluminum chassis, the chassis surface all the use of brushed oxidation coloring process, all-aluminum knob, feel very good
-resistance selection of five-ring metal resistance, the main circuit with a precision of 1% of the five-ring metal film resistors to ensure a good signal to noise ratio.
- PCB with 1.6mm thick double-sided sheet, 2.0 oz copper thick, spray tin all the process to ensure the size of the current through the performance. First-class PCB quality.
-board set sealed 15W transformer, the input voltage is 110-220V, no need to add transformer
The output of the board is part of the reference Lehman line design, Germany Leiman Er put the amp "in the Rolls-Royce," said the music expressiveness is no doubt, but the price of more than 4000 yuan so many low-calorie Prohibitive,
power tube current over 20MA full board in class-A working state, the whole music performance is very good
n board LM317 / LM337 next to the four adjustable to adjust the plus or minus 12V to the op amp power supply, BC capacitor next to the four adjustable resistance is used to give two I / V op amp 1 feet 7 feet with the zero All the op amp can be zero to reduce the DC output components, so the sound quality will be better
