L9023DAC SE 192K/24bit Hifi Fever Decoder Soft Control ES9023 Assembled Board
Potentiometer parameters
- Digital input: coaxial, optical fiber
- Analog output: RCA analog output
- Digital input code check: 16-24bit, 44.1-192K
- Analog output level: 2Vrms
- Power supply: DC 12-15V
- PCB size: 80*70mm
Special design:
- To increase the adaptability of external power supply, the input port is added CLC filter, even adopting switch power, the sound is still very smooth and soft, not the digital sound
- Power supply is the most important part in decode. This decoder adopts two grade stabilization strategy. The first grade adopts 9V serial connection stabilization, the second grad is divided into three channel, two of them supply power for digital receiving system and MCU, other channel supply ES9023
- MCU control, also the control parameter of singlechip machine
- LED will display locked frequency and input power
- Two grade RC resistor LPF circuit
