Product Details:
This machine has 4 digital signal input switches: USB, coaxial, optical fiber, Bluetooth.
This machine has 2 stereo RCA unbalanced outputs: normal output, tube buffered output. It is convenient to match the tube amplifier or integrated amplifier to obtain different effects.
The main amplifying board adopts double-sided board design, black high-grade solder resist.
Digital reception and digital-to-analog conversion adopt the well-known CS8416 of CIRRUS and PCM1794A of TI.
The electronic tube output part of this machine adopts medium-frequency and warm 6N3 vacuum tube, with soft tone, high voltage and filament are DC regulated power supply.
Powered by R type transformer with superior performance, high efficiency and low magnetic leakage.
The digital part and the analog part are independently rectified, filtered and stabilized for power supply to reduce interference.
The functions of this machine are controlled by MCU, and the channel status and volume level when the machine was last turned off.
Electronic volume adopts CS3310 chip, electronic volume, good synchronization, long life, no noise.
The headphone amplifier uses TPA6120 chip.
