TECKEEN TPA3116D2 Bluetooth Audio Amplifier Board - 2.1 Channel 100W+50W+50W

The main product parameters: Size (L*W*H): about 101 x 100 x 25mm, excluding potentiometer and socket projection. Operating voltage range: DC 12-24V (current 3-4A, or 19-24V / 4-5A, such as high power requirements 20-24V / 8-9A above) Note that the DC no-load voltage should not be greater than 25.5V. Bluetooth receiving distance:> 8 m (meters) Audio input sensitivity: 600-800mV Frequency response range: 20Hz-20KHz Speaker impedance: left and right channel speakers: 4-8 ohm, bass speaker impedance: 2-8 ohm The output power is related to the supply voltage/current, the speaker impedance, and the size of the audio input. When the power supply voltage/current is sufficient, usually the power supply voltage is higher and the relative output power can be made larger. Speakers with different impedances have different output powers. Usually, the speaker impedance is smaller and the power is easier to achieve. Function switch Instructions for use: 1. Plug in the power on default Bluetooth mode. 2. Bluetooth disconnected, long press the switch can switch to the audio input mode. 3. Bluetooth play status, short press the switch to pause / play; May be you also want TPA3116 subwoofer amplifier with case/acrylic case. Package included: 1*TPA3116 Bluetooth Audio Amplifier Board
