This is TDA7297 power amplifier board, with terminal, 2.0 dual-channel 15W+15W, can be connected to 4-8 euro10-50W speakers, small size, large volume, wide range of applications.
1. Volume: 53x48x42mm (length x width x height, excluding potentiometer handle), super small volume suitable for any space.
Voltage: AC or DC 9-15V, RECOMMENDED DC voltage 12V, current 2A or above
Power: 15 w + 15 w
Output impedance: 4-8 ohms
2. Advantages of this board: no current impact sound, high fidelity no static noise! Sound quality. Good -- delicate, soft, transparent, no obvious harsh; The bass is firm, full, powerful and free. . Recently, a small number of customers have reported that the board has a little noise, mostly because the power supply problem has not been solved. After testing, with more than 12V2A battery or more than 12V30W transformer power supply no noise, if using switching power supply or other variable power supply, because of the linearity may produce low noise.
3. The core of the power amplifier board is the original imported TDA7297 dual-channel power amplifier chip, which is produced by the famous European SGS-Thomson Microelectronics Company. Power supply design for direct current power supply, available 12V battery direct power supply, voltage range: 9-15V, recommended voltage 12V, output power up to 15W+15W, peak power up to 30W+30W, small volume but sound. Shock, applicable to any occasion.
