Product description
Working voltage: DC 9-17.5V
1. The product is made of high-quality materials with guaranteed quality
2. Stable product performance and long service life
3. Power amplifier chip: TDA7379, front-end amplifier chip: NE5532 stable power supply
4. Maximum output power: 39W X 39W
5. R8 and R10 are the magnification settings for resistors (default for shipment is around 2-3 times magnification, and the magnification can be changed according to one's own needs. The resistor can be selected from 10k-47k, and the larger the resistance value, the higher the magnification. If using a plug-in resistor, the original chip resistor can be removed and soldered onto the pads at both ends of the chip position).
Can provide high resolution and good dynamic range of sound, so that the sound quality of your audio equipment is significantly improved.
The power amplifier Board provides up to 38W of sustainable output power, and is stable and reliable. It will not cause power attenuation or distortion due to long-term use, meeting the audio demand of daily home and professional occasions.
It has good compatibility and can be easily installed on most audio equipment. Whether you are a professional audio engineer or a DIY enthusiast, you can easily master its usage.
Compared with similar products, it has higher sound quality and driving capability. Both professional sound system and entry-level sound equipment are ideal upgrade options.
This power amplifier board is sold without a heat sink. Before testing the power amplifier board, it is necessary to add a sufficiently large heat sink (7809 regulated IC does not require a heat sink).
Due to manual measurement, please allow an error of 1-3mm. Please ensure that you do not mind before bidding.
