Product Description

Product details
This is TDA7297 power amplifier board, with a terminal, 2.0 dual channel 15W +15W, can be connected to 4-8 euro 10-50W speakers, small body and large sound volume, a wide range of applications.
1. Ultra-small size for any space.
Voltage:  9-15V, recommended  voltage 12V, current 2A above power: 15W+15W Output impedance: 4-8 ohMs
2. The advantages of this board: no current impact sound, high fidelity no static noise! The sound quality is good. The treble is delicate, soft, transparent, without obvious harshness; The bass is firm, full, powerful, and easy to rewind. Recently, a small number of customers have reflected that this board is a little noisy, mostly because the power problem has not been solved. After testing, with more than 12V2A battery or more than 12V30W transformer power supply there is no noise, if using switching power supply or other variable power supply, due to poor 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 European SGS-THOMSON Iifa Microelectronics Company. Power supply design for direct current power supply, 12V battery can be used for direct power supply, voltage range: 9-15V, recommended voltage 12V, output power up to 15W+15W, peak power up to 30W+30W, the volume is very small but shocking, suitable for any occasion.
