KYYSLB TDA7294 amplifier board HiFi fever level mono 100W high-power audio amplification module

Usage precautions: You must use a transformer with 3 wires, both 12-32 can be used, and you must stick the heat sink yourself. Don't ask why it's not working, it's just not working!!! Don't talk about theory either!! Neither direct current nor battery works!! Immediately explode!!! Dual DC and dual batteries are not working either. They burn when powered on, and if you break them yourself, don't come looking for them! Don't come if you don't accept it! Product features: Special attention: Be sure to install a radiator!! Otherwise, it will generate severe heat and cause the machine to burn out or explode! 1. This circuit is an official standard circuit, stable and reliable. 2. The filter adopts a large electrolysis with a withstand voltage of 50V and a capacity of 2200uf. 3. Power supply voltage: Dual 12-36V ring voltage, recommended to use dual 32V ring voltage 4. Output power: 85W * 1 undistorted rated power, peak power 100W 5. Can easily drive speakers over 100W, speaker impedance: 4-8 ohms 6. PCB size: 50 * 50mm
