915 Generation TPA3116D2 Bluetooth 5.0 High-Power 2.0 Digital Audio Amplifi

1. This is a DC12-24V single power supply, with TI's TPA3116D2 high-performance digital power amplifier chip as the core, which can support 50W (left channel) + 50W (right channel) dual-channel output.
2. Support bluetooth audio receiver, with external audio input interface, bass, midrange, treble three-tone potentiometer, function control switch/volume adjustment potentiometer.
3. Wide working voltage, power saving design, efficiency up to 90%. You can use a good switching power supply, a laptop switching power supply, a charging or a car power supply, etc.
4. The board is a finished board that has been soldered and tested. Connect the speakers as shown, connect the appropriate power source, connect a Bluetooth audio device, or connect the audio input.
5. Power on: Default bluetooth mode, for bluetooth audio device to connect. Source input player: Bluetooth disconnected state, press the volume potentiometer switch, switch to source input mode Parameters:
1. Size: 110 x 83 x 25mm
2. Operating voltage range: DC DC12-24V (current 3-4A, for example, the above power supply requires 20-24V/5-6A) If an alternating current (AC) transformer power supply is used, a rectifier filter must be added to the DC power supply, can use. Note that the DC no-load voltage should not 25.5V
3. Bluetooth receiving distance: 8 m, Bluetooth version 5.0, -free, can block the receiving distance, and the Bluetooth performance of the mobile phone itself will also affect the receiving distance.
4. input sensitivity: 600-800mV; frequency range: 20Hz-20KHz
5. Speaker impedance: 4-8 ohms
6. Output power: Power 12V /8 Ohm Speaker 10W x 2; 12V /4 Ohm 15W x 2; 21V /8 Ohm 30W x 2; 21V /4 Ohm = 50W x 2; 24V/8 Ohm 35W x 2; 24V/4 Ohm greater than 60W x 2
This is based on the above test conditions, the actual test data on the instrument, and the output power is related to the power supply voltage/current, speaker impedance, and the size of the audio input. When the supply voltage/current is sufficient, the supply voltage is usually higher and the relative output power can be made larger. Speakers with different impedances also have different output power. Typically, speakers have less impedance and more power
