Product name: PCIE-USB3.0 S2T2 OCXO high-precision clock OCXO crystal oscillator PCHIFI audio dedicated Number of USB3.0 interfaces: 2 Suitable slot: PCI-EX1 X4 X8 X16 Voltage and current: DC5V/2A Operating system: Support XP, Win7, Win8, Win8.1, Win10 Transmission rate: 5GB High baffle size: length 125MM * height 120MM (including baffle) * thickness 35MM (constant temperature crystal oscillator thickness 27MM) Weight: Net weight: 0.12Kg Package weight: 0.22Kg
Advanced audio enthusiast PCIE×1 USB3.0 expansion card Dual USB3.0 port output.
Product features: dual card design, one USB card equipped with integrated OCXO module, suitable for chassis with ample PCIE slot position, one USB card with OCXO module can be installed separately, suitable for narrow chassis. The long baffle has a 5V DC5.5/2.5 or DC5.5/2.1 power port, which can be connected to an external power supply to improve the quality of power supply.
Use high-precision, high-stability, low-noise constant temperature OCXO crystal oscillator, with an accuracy of 0.01PPM. Matching full-height, half-height short baffle.
Sound quality features: dynamic sound, sharp dynamics, three-band equalization, good sound field level, high analytical power, rich details, wide and deep sound field without holes, an excellent choice for PCHIFI audio USB output channels. Independent power supply to get rid of the trouble of insufficient power supply and asynchronous power supply frequency of multiple groups! Each interface is independent and a large 4DIN interface will never affect each other or interfere with each other!
Question 1: Why is the external power supply better than the power-free one?
Answer: Because the external power supply can avoid the electrostatic interference generated by the computer`s switching power supply, and avoid the unclean power supply, causing a series of noises, and the PCI power supply is reduced by the mainboard 12V, the mainboard has divided a lot of current and load for other hardware. The larger the loss, the greater the loss, and various instabilities will occur! External power supply can completely avoid these problems. The external linear power supply is regulated and supplied. The multi-level processed power supply is very clean and can provide a stable output of 5V, reducing other losses, and there will be no insufficient power supply!
Question 2: What are the benefits of upgrading a constant temperature crystal oscillator? What are the improvements?
Answer: There are too many benefits to upgrade the constant temperature crystal oscillator. The constant temperature crystal oscillator has high accuracy. More importantly, the temperature of the constant temperature crystal oscillator is internally used to ensure accurate positioning and accurate clock positioning, which greatly improves the sound dynamics, sound density, and quiet sound background. , Layering, and details are all handled well. These benefits are not the same.
Question 3: Can the computer power supply be directly powered by 4DIN? Will it affect the USB expansion card?
Answer: The direct power supply of the computer power supply does not affect the use, but relatively speaking, it is not as clean as the external power supply, which will cause the interference of the USB device, and the expected effect will not be achieved. Thicker, if you say that the upgraded constant temperature crystal oscillator has been greatly improved, then using a linear power supply, the output sound background is quiet, and the sound field is extended. There are obvious consolidation and improvement, so Xiaoshuai reminds everyone that the linear power supply is clean and very clean. It`s important, you can compare it to understand it.
