5 Bit Gigabit HIFI Audio Ethernet Switch Full Linear DC Power Supply SC Cut OCXO Constant Temperature Crystal Oscillator Upgrade

Description:
- The traditional magic change switch removes the original DC-DC switching power supply and adopts DC12V direct current power supply. But in fact, the switch motherboard uses DC12V power supply, and then it still needs to be converted into 3.3V and 1.2V low-voltage direct current power supply to each chip through the DC2DC high-frequency switching regulator chip on the board. However, the switching regulator chip on the motherboard still brings high-frequency switching noise, so this solution cannot completely remove the noise caused by the switching power supply regulator chip. This machine directly uses the 2-level multi-channel low-noise pure DC power supply composed of LM1085 and lt3045 to supply the chip on the motherboard. The power noise is as low as uV, which greatly reduces the various noise and interference on the board, which is expressed in the amount of sound information. Without reduction, the background is purer, and the high frequency is more rounded and shiny.
- High-precision OCXO constant temperature clock
- Unlike most merchants in the market who use OCXO grinding machines from small domestic workshops, this machine uses a genuine imported high-precision SC-cut OCXO constant temperature crystal oscillator, replacing the low-end 2-pin crystal oscillator of the original switch, which greatly improves the clock accuracy and reduces the clock pulse. Dithering makes the sound details significantly richer, and the sound field positioning is more accurate.
