Vender Two Channel Amplifier Board Stereo for DIY Store Theater Square Speakers al mejor precio

Description: The potentiometer adjusts the volume, with a switch, it is convenient to control the volume, which is very suitable for DIY speakers. If it is a metal box, the Bluetooth antenna needs to be led out. The copper DC connector is used, which can withstand high current and does not generate heat. Capacitor 470UF35V solid capacitor, to ensure the power storage and heat dissipation capacity, providing stable and continuous is the prerequisite for good sound quality. The 5.0 Bluetooth version has higher transmission efficiency and longer transmission distance. Specification: Size:55x38x17mm 2.17x1.5x0.67inch Adapted power supply voltage: 5~24V (optional 9V/12V/15V18V/24V and other adapters, high power recommended high voltage) Adapted speakers: 30W~200W, 4Ω~8Ω Number of channels: left and right dual channels (stereo) Bluetooth version: 5.0 Bluetooth transmission distance: 15 meters (unobstructed) Protection mechanism: self-recovery overheating protection, self-recovery short-circuit protection Power supply voltage: 12V—8 ohm speaker/12W (left channel) +12W (right channel), 4 ohm speaker/20W+20W Package Includes: 1 x Bluetooth power amplifier board 1 x Enclosure accessories 1 x DC cable Note: Tip:Only when the audio input is enough and the power supply voltage/current is enough, there will be enough output power. The higher the power supply voltage, the higher the relative power, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the greater the ohms of the speaker, the lower the relative sound power, please pay attention!
