Introduction: XH-A901 preamp tone board, suitable for use with power amplifier, can achieve audio amplification and high, medium and bass adjustment, so that you have a better listening experience. The original imported dual-core NE5532 chip is used; the power supply voltage is DC12~24V (note: the positive and negative poles should be distinguished when wiring), and the audio input is a 3P audio cable.

NE5532 imported chip: NE5532 is a dual operational amplifier, high performance, low noise operational amplifier. Compared to most standard operational amplifiers, such as the 1458, it shows better noise performance, improved output drive capability, and relatively high small signal and power supply bandwidth. This makes the device particularly suitable for applications in high-quality and professional audio equipment.
