H2 is a multifunctional desktop computer digital sound card. After connecting the computer with the distributed USB cable, it can output 3.5 analog signals, digital coaxial signals and digital optical fiber signals, many buyers consult where is the optical fiber output hole? Now make a special note (if the optical fiber output and analog output use 3.5 output holes together, after connecting the computer, the 3.5 holes will have red light, indicating that there is optical fiber signal output, can be connected with optical fiber cable with round head on one side and square head on the other side), it can not only connect audio equipment with analog input, but also connect audio equipment such as power amplifier with digital optical fiber signal input and digital coaxial signal input. Deliver one high-quality USB cable. H2 the chip uses the HIFI fever level PCM2704 USB decoding chip of BB Company, PCM2704 is a monolithic digital to analog conversion chip. It has two digital-to-analog conversion output channels and an integrated USB interface controller. This interface complies with the USB1.0 standard. It adopts the newly developed SPActTM (adaptive control tracking during the sampling period) system. The system can separate a stable clock signal with small deviation from the audio data of USB interface to coordinate the work of PLL and DAC.

1. Plug-and-play, Windows2000.XP. MAC, etc. are used as operating systems without drivers.

2. USB power supply: no power supply, direct computer power, easy to use

3. Analog output: gold-plated interface 3.5mm headphone socket stereo output, built-in ear amplifier, 3.5 headphone output has optical fiber output function at the same time, which can be directly connected to decoder.

4. Digital Output: Optical fiber output and RCA coaxial output. Coaxial output adds digital shaping circuit to output high-quality SPDIF digital signal.

5. The shell adopts aluminum shell, and the surface font adopts laser engraving.
