Product information:
Power: 15W
Purpose: Speaker power amplification module
Special service: Dual Channel
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 DC power supply, which can be directly powered by a 12V battery. The voltage range: 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.
Product parameters:
Voltage: DC 9-15V, recommended DC voltage 12V, current above 2A
Power: 15W+15W
Output impedance: 4-8 ohms
Net weight: 44g
Product advantages:
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 occur due to poor linearity.
