R93 AK4493 Decoding Board I2S 32BIT DAC Audio Digital Player Decoder for Raspberry Pi 2B 3B 3B+ 4B

R93 AK4493 Decoding Board I2S 32BIT DAC Audio Digital Player Decoder for Raspberry Pi 2B 3B 3B+ 4B

Board Output:
-Two-channel single-ended RCA block output: 2.45Vrms/-0dB
-3.5mm headphone jack (the headphone jack is actually connected directly to the RCA seat, not suitable for directly driving the headphone).
 
Powered:
-The 5V power supply of the board is directly connected to the 40P interface of the Raspberry Pi. There are two ways to supply power as follows:
a. Directly use micro_usb to power the Raspberry Pi, and power the board from the 40P interface of the Raspberry Pi.
b. Power is supplied from the DC-seat input interface of the board, and the board supplies power to the Raspberry Pi through the 40P interface.

Note:
1.Two kinds of power supply modes can only use one of them at the same time, and cannot use two types at the same time.
2.Otherwise it will cause damage to the board, raspberry pie or power supply.

DC Output Specification:
Power supply voltage: DC voltage regulator +5V, voltage range: 5%
Power interface specification: 5.5/2.5, inside and outside negative
Recommended supply current: >2500MA
Single board working current: 250MA (not include Raspberry Pi)

Features:
1. Raspberry Pi dedicated AK4493 decoder board, support 32BIT/384KHZ DSD128.
2. Professional I2S processing chip realizes DOP to DSD and recognizes I2S 16, 24, 32BIT audio format.
3. Support 32BIT/44.1-384KHZ DSD64-DSD128 output, full frequency music switching without popping sound.
4. Raspberry Pi outputs through I2S mode, playing music, smooth listening, real and natural, without the hard-to-detect pause which caused by USB play way.
5. Use the general version of VOLUMIO, MOODE, and set the I2S-DAC mode to HiFiberry DAC to play.
VOLUMIO universal version driver can support 44.1-192KHZ DSD64 output;
MOODE universal version driver can support 44.1-384KHZ DSD64-DSD128 output.
6. LPF op amp, low distortion, low noise OPA1612 op amp, power supply for dual voltage, plus or minus 15 volts, effectively play the potential of the op amp, not low voltage or single power supply solution comparable.
7. Two sets of DSD digital filter coefficients can be set by 6 sets of PCM digital filter coefficients by jumper combination, and a variety of different styles sounds can be experienced in one board.
