ToyX project EQ Linearizer study ....Battery Power

EQ Linearizer 電源是大問題,喇叭效率超過95dB時,100hz以下AC 60hz容易peak進去,over 4khz以上又容易有高頻訊噪,高音會ㄘㄘ聲,解了下面100hz訊噪,over 4k 訊噪不好解 ,所以用電池.





The Battery box usage 4 cells (2S2P) Li-ion output 8.2V/5.2A (peak current limited in 5A).
No fuse and auto Over current ,Low Voltage,Over Temperture protection.




The EQ Linearizer remote power circuit clamp chock to reduce EMI influence.
L Channel and R Channel power path add diode to separate cross influence.




The battery module could stand alone into charge mode . So no AC noise.

The battery cells will  separate to open and charging by single cell  charger therefor no unbalance issue.
