Single supply low pass filter board subwoofer preamp board 2.1 channel DC10-30V Creek

Most of the front stage boards of subwoofers on the market are equipped with dual power sources, which is not very convenient for DIY enthusiasts to use. After all, single power sources are relatively easy to find. Under the premise of ensuring effectiveness, we have introduced a single power source overweight bass front board, which can share a set of power sources with the rear stage amplifier board, making DIY very convenient.

Features of this board:

1. All the components are selected from the brand new first-class products. The original Philips CBB capacitor is selected as the frequency regulating capacitor. The fully sealed type made in Taiwan is selected as the regulating potentiometer. The input and output terminals are pure copper terminals, which are very convenient for wiring.

2. The operational amplifier adopts Texas NE5532, with an IC socket that can be replaced at any time, to experience the effects of different operational amplifiers and improve playability.

3. Designed with LED indicator lights for real-time monitoring of power supply conditions.

4. The PCB design of this board is simple and beautiful, with reasonable wiring, making it have a high signal-to-noise ratio and strong anti-interference ability. When there is no signal input, almost no noise can be heard near the speaker.
