Hi ,everyone! This is the TDA7297 power amplifier board, with binding posts, 2.0 dual-channel 15W+15W, which can be connected to 4-8 ohm 10-50W speakers, small size, large volume, and a wide range of applications.The core of this power amplifier board is the original imported TDA7297 two-channel power amplifier chip, produced by SGS-THOMSON in Europe. The power supply is designed to be powered by direct current, which can be directly powered by a 12V battery. The voltage range is 9-15V, the recommended voltage is 12V, the output power is up to 15W+15W, and the peak power is up to 30W+30W.The volume is small but the sound is shocking, suitable for any occasion.
Advantages:No current impact sound when booting, high fidelity without static noise!
Good Sound quality - the treble is delicate, soft, transparent, without obvious harshness;
the bass is strong, full, powerful, and freely retractable.
Please notice:
if you feel 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 powered by a battery above 12V 2A or a transformer above 12V 30W. If the power supply is powered by a switching power supply or other variable power supply, low noise may be generated due to poor linearity.
