Description
NE5532 10-24V 2.1 Amplifier Board Low Pass Filters NE5532 Low Pass Filter Board Subwoofer Front Stage Tone Board
Product Description
The product innovation adopts a single power supply, which can share the power supply with the power amplifier board, which is very convenient. The op amp adopts NE5532, and the op amp IC seat is welded, which is easy to replace the op amp and improve the playability. The potentiometer adopts high-quality closed potentiometer.
Features
1. With full-frequency signal volume adjustment potentiometer, it is very convenient to change to 2.1 power amplifier board front stage 2. There are LED indicators to monitor the power status in real time 3. The double-panel design is adopted, and the signal transmission is simple and the signal-to-noise ratio is very high. 4. Single/dual channel input, mono output 5. The PCB is made of ultra-hard FR-4 glass fiber board, board size: 82x30mm, excluding the protruding part thickness: 1. 6mm 6. The frequency adjustment range is 22Hz-300Hz. There is no human voice in this frequency range. The so-called low-pass only has low-frequency output. It can only be used with a power amplifier board with post-amplification. The low frequency performance is related to the power of the power amplifier board and the matching of the speakers. Please choose different power amplifier boards and subwoofers (passive subwoofers) according to different occasions.
