Taidacent Studio Recording Full Duplex Coaxial Fiber 5V Raspberry Pi Sound Card Pcm2704 Usb Amp Dac Decoder External Sound Card
Product Description
Introduction
The main chip uses BB's HIFI-grade PCM2704 USB decoding chip, which has better performance than the most commonly used low-end chip CM102S series on the market. The power supply uses USB power, and the output can be directly connected to headphones or the front stage. The more advanced DAC decoder provides SPDIF digital signals to get better sound quality. Because it is an external sound card, it avoids serious electromagnetic interference in the chassis, and the signal-to-noise ratio and sound quality are improved.
PCM2704 is a single-chip digital-to-analog conversion chip. It has two digital-to-analog conversion output channels and an integrated USB interface controller. The interface complies with the USB1.1 standard. The PCM2704 can receive 16-bit stereo or mono audio data at 48KHz, 44KHz, and 32KHz sampling rates. The chip's integrated software volume and mute function can adjust the computer's volume and mute simultaneously.
