[FAQ]
If your DAC+ board can not work properly, please follow these instructions:
1. At first, Please check if your DAC+ configuration is right:

Notice: Please remember to reboot the system after you complete and save all the configuration.
2. Please have a check if your audio format is supported .(Such as do not support DTS, AC3,DSD, and other multi-channel audio source formats)
3.If the problem still can not be solved, please try to replace the power supply and power supply cable.
4.When you hear the sound like noise, actually it is not noise, maybe your decoding is not right, so you need to check your configraution. You can try runeaudio or moode.If you still can not solve the problem, please send us the screenshot of your volumio configuration,we will ask for the technician to check for you!

This is a very beatiful dac board with a pair of RCA jacks, It’s suitable for Raspberry Pi 3 Model B / 2B/ B+,No external power supply needed.You can setup a open music player by volumio system.Perfect compatibility raspberry pie official PI HAT size, gold plating process of tall based on PCB board, arc wire (high-end HIFI DAC adopts arc wire), better guarantee the impedance of the signal continuity, reduce the signal reflection and refraction.Provided with an infrared receiver interface.
Upgrade DAC chip, using PCM5122 chip of high end, using I2S interface, and can be through the I2C interface to adjust audio volume parameter adjustment; supports 16 to 32 bit audio data format; distortion and dynamic is very ideal, support the tall sampling rate of 384kHz, 112dB dynamic range, degree distortion -93Db.For with no sonic boom run 120dB squelch signal to noise ratio (SNR).soft upward or downward oblique wave and analog squelch.
PCM5122 also integrated negative charge pump, the output without DC blocking capacitor; 2.1Vrms ground center output; ability to suppress very good band noise. Through the load support low to 1K, PCM510xA can drive a plurality of parallel products.
Output ports with gold plated RCV dual terminal and gold-plated 3.5mm Headset seat. The isolated power supply design, make the raspberry pie power supply and DAC part of the independent power supply isolation, and through the bead altogether without mutual interference, get rid of the current sound
Welding free, direct plug expansion board can use, and the use of I2S interface direct decoding digital to analog, non USB DAC interface.increase for double color LED provides state display, red for DAC power indicator (power normal bright), the green light for the working condition of DAC lamp (decoding and bright, stop or does not work out), better understanding of DAC work.(For the installation,Please refer to the picture)
