Class D 2.1 Amplifier Board High Power Digital 3 Channel Heavy Bass HIFI Amplifier for DIY Audio

Class D 2.1 Amplifier Board High Power Digital  3 Channel Heavy Bass HIFI Amplifier for DIY Audio

Description:
The power amplifier board has been welded , can directly connected to the power source, the audio and  speaker. This product uses two pieces TPA3116D2 digital power amplifier chip as the core, one is to do left and right channel power amplifier, the other is to bridge to the ultra . The working voltage is single power supply 12V26V. Left and right channel output is 50WX2, super bass maximum output is 100W, efficiency can reach more than 90%, can be used to switch power supply to notebook computers, but also very suitable for battery power supply, such as motorcycles, cars, electric cars and so on.  

Parameters:
- Board size: 100x84.5x28mm (LxWxH)  (not including the potentiometer and other socket protruding parts)
- Operating voltage: 12 - 26V DC (recommended: 19V4.74A).
- Output impedance: 2 - 8Ohm
- Output power: 50W for left and right channel; heavy bass is 100W+.
- Input impedance: 20KOhm
- Signal input: P-P 800-1500mV
- Frequency response: 18Hz-20KHz (+ 3dB); 10-180Hz (bass)
- Distoration: heavy bass: <10%/ DC24V/3Ohm /100W
   Left and right channel, 1%/DC24V/4Ohm/50W

Feature:
1.Boot delay output protection, no impact sound, to protect the expensive horn unit
2.High power output , low distortion, high sound reduction. No noise.
3. Comes with a large current toggle switch, the motherboard can be completely closed power, often without the power plug
4.Kinds of audio input mode, standard 3.5MM audio input socket, or from the 3P socket input audio, to meet the different module connection
5. support connection MP3 decoding module, with regulated power supply output
6. Anti-circuit design, avoid the use of improper or power supply polarity reversed that will ruin the power amplifier board
7.High quality radiator
8. Apply imported chips, high quality components, SMT chip technology
9.Reasonable  layout

Package included:
- 1 x Class D 2.1 Amplifier Board
