PCM2704 USB sound card/DAC, size: 58 * 58 * 24 mm Input: USB Output: coaxial, optical fiber, analog 3.5mm. Main chip HIFI level PCM2704 USB decoding chip(made by BB company), its performance is superior to the most commonly used on the market of microchip CM102S series. Power by USB port. Output can be directly connect headphones, also can do Pre-amplifier. in order to get better sound quality, digital output to provide more advanced DAC decoder SPDIF digital signal. Because it is the external sound card, to avoid the serious electromagnetic interference inside the case, signal-to-noise ratio and the quality is improved. PCM2704 is a monolithic analog-to-digital conversion chip.It has two analog conversion output channel and one integrated USB interface controller.The interface is in conformity with USB1.1 standards.PCM2704 can receive 44 KHZ and 48 KHZ, 32 KHZ sampling rate of 16 bit stereo or mono audio data, volume and mute function of chip internal integration, and can adjust the volume of the computer and synchronous mute. PCM2704 parameters: The power supply voltage: 5 V (USB power supply), Distortion: THD + N: 0.006% (RL > 10k ohms) Distortion: THD + N: 0.025% (RL = 32 ohms) Signal to noise ratio: 98 dB Dynamic range: 98 dB Headphone output power: 12 mW (RL = 32 ohms) Support the sampling rate: 16 bit and 32k, 44.1k, 48k Package include: 1 * PCM2704 sound card with case
