TDA7297 power amplifier board, with binding posts, 2.0 dual-channel 15W15W, can be connected to 4-8 ohm 10-50W speakers, small size, volume, and a wide range of applications.
Voltage: DC 9-15V, recommended 12V, current above 2A
Power: 15W15W
Output impedance: 4-8 ohms The advantages of this board: no current impact sound when booting, high fidelity without static noise! The sound quality is super good - the treble is delicate, soft, transparent, without obvious harshness; the bass is strong, full, powerful, and freely retractable. Recently, a small number of customers reported that the board is a little noisy, mostly because the power supply problem has not been solved. After testing, there is no noise at all when using a battery above 12V2A or a transformer above 12V30W. If it is powered by a switching power supply or other variable power supply, low noise may occur due to poor linearity.
