Sell Tpa3116d2 HIFI Power Amplifier 2.1 Bluetooth 5.0 50Wx2+100W Subwoofer best price

Description: Supported the reception of bluetooth audio. The amplifier board is designed with pre-amplifier and low frequency technology. Though the bass system, you can adjust the left or true channel, high-pitched channel. Used DC 12-24V power source, which can have high power output. Designed with wide operating voltage and power-saving, which can reach more than 90% of efficiency. Specifications: Size (L x W x H): 101 x 100 x 25mm, excluding potentiometer and projection socket Operating voltage range: DC 11-25V (current 3-4A, or 19-24V / 4-5A, like ace high power requirements 20-24V / 8-9A above) Note that the DC no-loading voltage should not be large than 25.5V. Bluetooth receiving distance: > 8 m (meters) Sensitivity input audio: 600-800mV Frequency response range: 20Hz-20KHz Speaker impedance: left and right channel speakers: 4-8 ohm, speaker bass impedance: 2-8 ohms The output power is relative to the supply voltage/current, the speaker impedance, and the size of the audio input. When the power supply voltage/current is sufficient, normal 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 simple to achieve. Instructions switch function for use: -Default Bluetooth fashion power-on plugin -Bluetooth Disconnected, long-press the switch can switch to the audio mode input -Bluetooth Play status, short press the switch to pause/play Package includes: 1x TPA3116D2 HIFI Power Amplifier 2.1 Bluetooth 5.0 50Wx2+100W Subwoofer 1x cable audio input 5x potency knob 4x screw + nut Note: the color in the picture may be different from the real.
