2*50W Bluetooth 5.0 Amplifier Board TPA3116 Amplifier 2 Channel Power Amp Stereo w/ Tone Knobs

Features:

1. This is a DC12-24V single power supply, with 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, middle tone, treble potentiometers, 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, you can also use a car power supply.
4. The board is a finished board after welding and testing. Users connect speakers themselves, connect appropriate power supply, connect Bluetooth audio device, or connect correct audio input.
5. Power on: Default Bluetooth mode, is waiting for the Bluetooth audio device to connect.
6. Source input player: Bluetooth disconnected state -> press the volume potentiometer switch -> switch to source input mode.

Main Technical Parameters:

- Operating Voltage Range: DC 12-24V (current 3-4A. For example, the above power supply requires 20-24V/5-6A). If you use an AC transformer power supply, you must add a rectifier filter on the DC power supply. Please note that DC no-load voltage should not exceed 25.5V.
- Bluetooth Receiving Distance: > 8m (Bluetooth version 4.2). Barrier-free reception distance, and the Bluetooth performance of your mobile phone will also affect the reception distance.
- Sound Source Input Sensitivity: 600-800mV; Frequency Range: 20Hz-20KHz
- Speaker Impedance: 4-8 ohms
- Output power:
* Power supply 12V /8Ω speaker> 10W x 2; 12V /4Ω> 15W x 2;
* 21V /8Ω> 30W x 2; 21V /4Ω = 50W x 2;
* 24V /8Ω> 35W x 2; 24V /4Ω> 60W x 2.

Attention:

This is based on the above test conditions, the actual test data on the instrument, the output power is related to the power supply voltage/current, speaker impedance, and the size of audio input. When the power supply voltage/current is sufficient, the power supply voltage is usually higher, and the relative output power can be made larger. Speakers with different impedances also have different output powers. Generally, speakers have smaller impedance and greater power.

Package Included:
- 1 x Set of Power Amplifier
