Tone Amplifier Preamplifier Board BBE Sound Effect Exciter Improve Treble Bass Volume Control Module

Chip design, with treble and bass adjustment, enhance high and low bass clarity, enhance dynamic effect.The adjustment of potentiometer adopts control mode, and the separation of potentiometer will not cause interference.Easy to use single power supply.The high-pitched potentiometer has two functions :1: When the potentiometer is adjusted to the leftmost end (clockwise 3/1 range), the BBE is passed through (that is, the BBE function is turned off); After 2:3/1, adjust the potentiometer clockwise, the range is to turn on the bbe function, and the potentiometer is used to adjust the treble at this time.This eliminates the need to add bbe switches. By adjusting the high-pitched potentiometer, the bbe can be controlled on and off, which is more convenient to use and achieves two purposes.PCB board size :72mm*33mmPotentiometer spacing :35mm(fixed potentiometer version)Operating voltage: 12.5-24V or AC 9-16VPacking list: Audio Amplifier *1 (excluding other exhibits)Notes:Due to manual measurement, please allow an error of 2-3 cm.The actual color may be slightly different from the picture due to different lighting.It features stable performance, a wide frequency response range and application scope, making it suitable for various industrial DIY scenarios
