TZT V4 R2R DAC Audio Decoder Zero Background Noise 0.1PPM TCXO High Precision Dynamic Compensation Decoder

Description:
- R2R decoder V4, zero background noise, fourth generation dynamic compensation decoder with one in ten thousandth precision resistor (0.01%). The difference from previous versions is that V4 manually selects the first 8 resistors of the array and compensates for the resistance values using wafer resistors. The effect of doing so is to make the accuracy of the resistor array far exceed one in ten thousandth, completely solving the problem of bottom noise. The operational amplifier supports plug-in replacement and has strong playability. Supports both coaxial and USB interface input, compatible with all devices, comes with volume adjustment function for headphone connection, supports RCA, 3.5, 4.4 output. Supports both home and car use. The double-layer motherboard design compresses the size to 10x12x3cm, which is very exquisite.

- The main features of this decoding are a large sound field, high dynamics, thick and smooth vocals, delicate high frequencies, strong low frequencies, strong spatial sense, precise positioning, and very durable listening. Compared with the previous generation, it has improved the signal-to-noise ratio and reduced the background noise, while increasing the simulated flavor and low-frequency atmosphere. It can be said that it has reached the level of ten thousand yuan.

The upgraded points for V4.0 are as follows:
- Upgraded crystal oscillator: Customized 0.1ppm, TCXO temperature compensated crystal oscillator.
- Upgraded shell: All aluminum alloy anodized black oxidation.
- Upgraded operational amplifier: Original 4625-2, one-step solution.
- Upgraded connectors: Customized connectors with thick gold plating are used.
- Upgraded potentiometer: for ALPS potentiometer to eliminate bass distortion.
- Upgraded power supply: The entire board is equipped with capacitor filtering for Sanyo, using multi-stage linear stabilizing LDOs such as LT1764, TPS7A, LP5907, etc., to control the ripple at the UV level.
- Upgraded resistor array: In case of precision resistors + for Vishay wafer resistors, the scale will double and the accuracy will double too.
- Operational amplifier plug-in design, with strong playability.

Package Included:
- 1 x V4 Decoder
- 1 x Thunderbolt5 Data Cable (0.8m)

Note:
- The linear power adapter is not included.
