ماژول آمپلی فایر استریو TDA7297

TDA7297 power amplifier board, with binding posts, 2.0 dual-channel 15W+15W, can be connected to 4-8 ohm 10-50W speakers, small size, large volume, wide application range. There is no current impact sound when starting up, high fidelity and no static noise! The sound quality is super good-the treble is delicate, soft, transparent, without noticeable harshness; the bass is strong, full, powerful, and freely retractable. Recently, a small number of customers reported that the board is a bit 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 you use a switching power supply or other variable power supply, it may produce low noise due to poor linearity.

The power amplifier board is designed with reference to the official standard circuit. The PCB circuit board uses a 1.6mm thick FR-4 high-quality fiberglass board with reasonable wiring and compact component layout. There is no current impact sound when starting up, and 100% no static noise.
