Optical fiber coaxial USB DAC decoding amp machine
The product of all parts are original authentic, chastity, pure quality; the use of high-quality original parts, is not only the safety quality guarantee,long service life, more important is the powerful guarantee to make the actual performance can meet the design target. The pursuit of first-classquality is our consistent aim.
The original AD1955+WM8805+PCM2706+ (AD827)
Electrolytic capacitor signal the main circuit uses the Taiwan famous brand,the main filter capacitor using BC special electrolytic capacitor capacity of 2 × 2200UF, most capacitor using solid-state import capacitor, rectifier using a full wave bridge rectifier circuit, ensure the support strength Everfountpower.
The original Japanese ALPS potentiometer potentiometer potentiometer.
This machine adopts the whole aluminum chassis, the chassis surface all by drawing oxidation coloring process, all aluminum knob, feel very good!
Resistance selection of five metal resistance, the main circuit uses the metal film resistor accuracy of ± 1%, the signal-to-noise ratio of the good.
PCB employs 1.6mm thick double-sided board, 2 oz copper thickness,spray tin full process, ensure the size of the current good through the performance. PCB first-class quality.
The board set the whole sealing of 15W transformer, the input voltage is 110-220V, does not require an external transformer!
The board amp output part is a reference to Lehmann line design, the German Lehmann amp with amp “Rolls-Royce” said. Music expressive force beyond doubt, but the price of four thousand yuan it does make a lot of fever group and step back, power tube current exceeds 20MA the wholeplate is in the class-A state, the expressive power of music is very good
The board next to LM317/LM337 four adjustable is adjusted to positive and negative 12V op amp for the power supply, BC capacitor beside 4adjustable resistor is used to give 2 pieces of I/V op amp 1 foot 7 footpocket! The op amp can all zero can reduce the DC output component, so the quality will be better!
Optical fiber, coaxial, USB audio signal input, earphone amplifier output or common audio signal output!
