AK4493 DAC Board Decoder Digital Player for Raspberry Pi 32Bit/PCM384KHz DSD128
Features:
- AK4493 decoder board special for Raspberry Pi, supporting 32BIT/384KHZ DSD128
- Professional I2S processing chip realizes DOP to DSD and recognizes I2S 16-, 24-, 32-Bit audio format.
- Support 32BIT/44.1-384KHZ DSD64-DSD128 output, full frequency music switching without popping sound.
- I2S output mode for Raspberry Pi. It plays music smoothly and naturally, out-rivaling USB playing mode in performance.
- Support the general version of VOLUMIO, MOODE. Set the I2S-DAC mode to be HiFiberry DAC to play.
Universal version driver for VOLUMIO supports 44.1-192KHZ DSD64 output;
Universal version driver for MOODE supports 44.1-384KHZ DSD64-DSD128 output.
- Low-distortion and low-noise OPA1612 op amp, power supply for dual voltage ±15V
- 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 sounds can be experienced in one board.
Output Parameters:
- Two-channel single-ended RCA output: 2.0Vrms/-0dB
-
3.5 headphone jack (the headphone jack is actually connected directly
to the RCA seat, not suitable for directly driving the headphone)
Power Supply:
The
5V power supply of the board is directly connected to the 40P interface
for your Raspberry Pi. There are two ways to power as follows:
a. Support direct power supply for your Raspberry Pi via micro_usb and its 40P port.
b.
Power is supplied from the DC-seat input interface of the board, and
the board supplies power for Raspberry Pi through the 40P interface.
Note: Please choose just one power supply mode while using. They can not be used at the same time or it may cause damage.
DC Input Parameters:
- Voltage of Power Supply: DC +5V, Voltage Range: 5%
- Power Supply Port: 5.5/2.5, Inner +, Outer -
- Recommended Current: >2000mA
- Board Working Current: 250mA
Note: Main board for Raspberry Pi is not included in this package. Thank you!
