또 손님...ㅎㅎ QA350 wav플레이어

항상 고쳐달라고 오는분들은 다 아는 형들이나 동생....

 

뭐 내가 잘하는것도 아닌데 집에 인두기 있다고 들고 오는득...-_-;;;

 

자 오늘의 손님은...

이넘데것음... wav플레이어... 유럽에서 왔다고 하는데... 역시 이붸이에서 땡김...  자 슬슬 껍데기 벗기자..ㅎ

 

전원 아답타가 있구 휴대용으로 쓰라고 Lipo 2cell 달려있음...  이거 충전기 만들어 달라했는데..

아직 2cell은 발란스 문제도 있구해서 만들어 보지 않음..

ㅎ 이건 걍 웹에서 판매하는게 있어서 구매하기로함.. 2cell 발란스되는 충전기 3점...

 

자.. 문제의 뒷면... SD카드 인식이 안된다던데... 카드를 빼면 no card, 카드를 넣으면 인식이 덴다..  no song 이라는 메시지가 나오는걸 보면 카드 인식이 데는거자나~~!!!! 

 그냥 냉납 문제 인줄 알았는데 점점 머리가 아퍼오기 시작...

 

 

 

DDC IC 쇼트인줄 알고 열라 조짐....  나두 이거 부품있는데 이거 맹그러야하는데..

싸이러스부품...-_-;;  2년전에 땡긴...

자..   뚜껑을 다시 덥고...

 

 

 

데나... 데나???  역시 no song...  응??  그럼 다른 wav파일 넣어볼까??  하구 다른 wav 파일 넣음...

재생됨...

갑자기 끗.... -_-;;

 

 

결론.. 휴먼에러!!!!  술 얻어먹기로 약속받음..ㅎ

 

 

 

 

 

좀더봐야것네...

mp3 -> wav 변환시 bit rate 와 헤더부분이 않맞으면 플레이가 않되는듯

일딴 QA350 spec과....

Features:

• Use 2PPM  11.2896 TCXO  Crystal (crystal JITTER is below 10PS)
• The power supply part use several LDO, respectively offer power for: crystal oscillator, the main chip, the digital output chip, DAC digital, DAC analog, headphone amplifier, display control, to ensure the best sound quality.
• In portable system, fever grade materials are applied: Kemet tantalum capacitors, YAGEO SMD 1% precision resistors, high precision SMD capacitor of Samsung, ELNA electrolytic capacitors, ALPS potentiometer.
• Lithium polymer battery of general specifications applied in the aircraft models serves for power supply. The benefits are:
  • Discharge in large rate and low internal resistance. Discharge current can reach couples of Ampere in a blink to increase the low frequency and transient explosive power of portable system.
  • Lithium polymer batteries applied in the aircraft models have common specifications and are easy to buy which facilitate users to replace batteries by themselves. (Batteries have certain usage life. Customized size / appearance bring great inconvenience to users for the subsequent replacement of the battery.) (Maximum supports of 55mm * 31mm * 16mm 7.4V lithium battery for model aircraft are available).
  • Model aircraft batteries commonly use high-quality battery cells and have enough stock and market verification for long time with stable performance and long service life.
• Provide a professional balance charger for models for the rechargeable lithium balance charge, which reduces the charging time, and expands long battery life.
• Onboard short-circuits protection and over-discharge protection ensures the battery life.
• QA350 directly applies 7.4V lithium battery. we spent a lot of time selecting high-end chip OPA and the OPA with good performance under low voltage. The whole player has no step-up circuit and reverse voltage circuit. The sound is transparent and pure.
• LDO filter circuit strictly matches ESR to ensure minimum ripple output.
• Firmware can be upgraded, and the upgrade is simple.
• Provide external power input interface, and the input voltage is DC9V-DC12V. When external power is input, the internal power supply will be automatically disconnected.
• When the internal battery is charging, external power supply is available. (We are not recommended to use battery offer power supply When the charging internal battery, which have significant impact on battery life).

Product specifications Indicators:

• Analog Output: LINE OUT, headphone AMP output.
• LINE OUT parameters: level 2V (RMS); frequency response 20hz-20Khz. SNR> 100dB; Distortion <0.005%.
• Headphone amp out parameters: 130mW/32ohm.70mW/16ohm. Frequency response: 20 Hz-20Khz. THD + N (total harmonic distortion plus noise): 0.009%.
• Headphone output matching impedance: 16 ohm --- 300 ohm
• Battery Type: 7.4V Li-Po battery of Model General Specifications, maximum size: 55mm * 31mm * 16mm; the capacity is usually among 800-1100mAH.
• Battery life: 6 to 8 hours.
• Charging time: 1.5-3 hours (when charging, playing music can available powered by the external power supply)
• Power consumption: 120mA-150mA (LCD backlight does not open) or 150-180mA (open LCD backlight)
• Specifications of matching charger: Support  2 cells Li-Po batterys balance charger. 
  Supply Voltage: 110-240V AC. 
  Maximum charge current: 800mA. Display: double-color LED instructions of charging charge status.
• Dimension: 135mm * 78mm * 27mm (excluding the output socket, switch, button, etc.) 
  150mm * 78mm * 30mm (with all the sockets, VR button, switch, button)

업데이트 방법

How to firmware update 
1.Please re-format 1G/2G SD card for FAT32.
2.Download update files from our website http://www.qlshifi.com/en/Download.htm 
and save them on your local hard disk. Decompress such files, extract the following *.qls file 
3.Please will update files (*.qls file) save to the SD card root directory . 
Note that file name can't be amended. 
(only can have this a *.qls file in your SD card root directory, Please delete it If have other *.qls file) 
4.Plug SD card, press on update key SWI("Backlight") and turn on the power supply. Then LCD shows “update   start∼” and 
the player will automatically find relevant files. 
5.If you don’t insert the card or it fails to find update files, LCD will show “NO CARD” or “no file”. 
6.After finish the update, LCD shows “update ok”.

이래서 S/W랑 물려있는 재품을 싫어함..ㅋㅋ

 

펌웨어 업데이트 후 파일 변환만 지대로 하니 이상무...

 

용량작고 변환 잘데는 mp3 -> wav 프로그램 첨부
