Taidacent subwoofer NE5532 front panel front panel low pass filter board non-amplifier single power NE5532 pre-finished board
1. All components are selected as the new first-class products. The frequency adjustment capacitors are made of the original Philips CBB capacitors. The adjustment potentiometers are made of fully sealed type. The input and output terminals are made of pure copper terminals. The wiring is very convenient. 2. The NE5532 is selected for the op amp. The IC seat can be soldered at any time to change the op amp, and the effect brought by different op amps can be improved. 3, designed with LED indicators to monitor the power status in real time. 4. The PCB design of the board is simple and beautiful, and the wiring is reasonable, which makes the board have a very high signal-to-noise ratio and strong anti-interference ability. There is almost no noise near the horn when there is no signal input
