HIFI Digital Sound Card I2S Digital Audio Expansion Board Optical Fiber Module For Pi 3/2 Model B
Function introduction:
1 the adoption of I2S interface; Supports 16 to 24 bit audio formats; distortion and dynamics is very ideal, support the high sampling rate of 192 kHz, advanced shake reduction technology can be intrinsic jitter control in 50 pcs RMS, high degree of reduction.
2. Use the optical output and coaxial output twointerface output, convenient for the user to connect an external power amplifier
3 hardware support modes for controlling volume ( I2C interface)
4. Power supply Raspberry PI supply, there is no need for external power supply; and use π power-type design filter to reduce power interference effectively.
5 using I2S interface direct digital output, high degree of reduction, no USB interface DAC methods, not busy raspberry plus extended GPIO
6. Provide the power light, easy to observe the state expansion board
7. PCB board adopt gold plating process, wire arc (high-end HIFI DAC to adopt arc line), ensure better signal Continuity Impedance, reduce reflection and refraction of the signal.
8 Good sound depends on real materials, fiber optic interface adopts imported HIFI grade high quality fiber seat, coaxial interface using Pluse audio import isolation transformer and good digital audio at the same time good protection of your audio device and boards !
9. Integrated infrared reception function, in the absence of network, more convenient to control playback (Foreign similar products remove this part for the cost, in order to sound for the sake of reliability we will not begrudge the cost, never cut corners)
Note: The matching copper pillars are gifts for this item!
