Bass is the processing circuit, low-pass filter, the output end is connected with the ordinary pure after the great power amplifier board, can be composed of subwoofer amplifier, signal input can be a mono or stereo (two channel input than mono input sound a lot better), use very convenient.The circuit board adopts the advanced glass fiber board, the wiring is reasonable, the circuit is well designed, the effect is good.

Frequency adjustment range of 22Hz-210Hz, the frequency range is no voice, the so-called low pass only low frequency output, the need to add after the amplifier board can be used. Low frequency performance of the power amplifier and power amplifier to match the speaker, according to different occasions choose different power amplifier board and bass speakers (passive subwoofer).

1. part of the large rectifier capacitor and 2 2200uf/25V filtering to do by the United States NE5532 (s, Op, Op Amp IC disassemble) welding, easy replacement of OP, ascension can be fun, all are PHILPS CBB capacitor capacitance potentiometer, using high-quality Taiwan produce closed potentiometer.

2. according to the input / output interface A board and B board, convenient user DIY, please specify when buying A board or B board, such as the default does not specify the A board.

3. there are LED lights, real-time monitoring of power supply.

4. reasonable PCB line plus excellent selection of materials, the basic noise.

5. input voltage: AC double 12V to double 15V can be.

6. single / dual channel input, mono output.

7. PCB uses super hardness FR-4 glass fiber board, specification: 78x42mm, thickness: 1.6mm.

Potentiometer from left to right are: frequency control, volume control

Low frequency: 22Hz-210Hz,

Power supply voltage: AC double AC12-15V (5W or above) must use independent transformer or independent winding
