Description
IC Amplifier Board Dual Channel 15W+15W No Noise 12V Amplifier Board Audio Digital Amplifier Board
Product Description
The core of this power amplifier board is the original imported TDA7297 two-channel power amplifier chip. 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 super shocking, suitable for any occasion.
Feature
This is the 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, and a wide range of applications. There is 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 powered by a battery above 12V2A or a transformer above 12V30W. If a switching power supply or other variable power supply is used for power supply, low noise may be generated due to poor linearity. The power amplifier board is designed with reference to the official standard circuit. The PCB circuit board adopts FR-4 high-quality glass fiber board with a thickness of 1.6mm. The wiring is reasonable and the component layout is compact. There is no current impact sound when booting, and 100% no static noise.
