Mini Home Audio System 4pcs Set Linear Power Supply + Media Player + DAC Decoder + Headphone Amp

Instruction:
DP-4 Stream Media Player
Raspberry Pi 4B platform, quad-core 1.5GHz 64-bit ARM Cortex-A72CPU super computing power. AK4137 design that with convertible sample rate (SRC), can be converted between PCM-DSD at will. The clock recovery circuit with ultra-low Jitter makes the streaming media playing clock reach a very stable level.

Support DSD256 Playback and with Downward Compatibility
You can access music files through SD card, mobile hard disk, WIFI, wired network, Bluetooth, etc., which greatly improves the convenience and compatibility of use.

DA-4 Full-balanced Decoder
Adopt AK4493 decoder chip, which is 123dB 768kHz / 32-bit 2ch Premium DAC chip, the most cost-effective chip in the 449X series, can greatly reduce noise, provides higher quality and pure sound, satisfying master tape HD format playback and reproduce real live music.

Pure Class A Headphone Amplifier
Adopt fully discrete (the circuit is built with transistors) fully symmetric circuit, superior to the transient response of asymmetric circuits, with lower cross distortion and every detail is full, rich and clear.

PO-4 Power Supply Unit
Independently powered, with dual configuration can satisfy different requirements
1. Pure DC storage battery configuration, adopt 12V 21Ah large-capacity lithium battery as power supply, 8-10 hours of long battery life, and the power supply environment is pure and interference-free.
2. AC adapter power supply, powered by linear large capacity toroidal transformer, and makes large dynamic voltage regulation by PO-4, which is cleaner than the switching power supply.
