2.TPA3116D2 high-performance digital amplifier chip as the core, parallel bridge bass channel power amplifier, support 100W (bass channel) output
3. External audio input interface, with preamplification, bass crossover processing: bass volume, bass frequency, switch/total volume, with 2 adjustment potentiometers
4.DC12-24V wide voltage operation, power-saving design, high efficiency of more than 90 per cent
5. Easy to use, the board has been welded and tested finished board, according to the picture connected to the speaker box, connected to the appropriate power supply, correctly connected to the audio input, can be used!
Amplifier IC: TPA3116
Operating efficiency: > 90%
Power supply: DC12-DC24V
Q: Amplifier board use current sound, noise?
A: Most of the products are powered by DC power supply, which does not produce current sound and noise.
1. Matching power supply filtering is not good current sound is the power supply or sound source input is not normal lead to
2. Poor quality of the input signal; the output of the device connected to the input playback is not normal noise is caused by the abnormal input of the audio source.
3. Poor quality of the input connection line; poor contact with the line; wiring damage; wiring overhang
A: 1. Speaker connection line is not through
2. Poor contact with the input connection line; wiring damage
A: 1. First confirm whether the wiring is correct, whether the power supply current is sufficient B, poor performance or damage to the speaker itself, the speaker power is too small or too large
2. Left and right channel speaker (+) (-) output is independent, can not be connected to each other!
A: 1 power supply positive and negative poles are reversed; power supply voltage is too high; beyond the working limit
2. Wiring should be correct, and then connected to the power supply, connect the wrong line will lead to a short circuit
A: Power and power supply voltage, the amplitude of the audio signal size, speaker impedance size are related to any kind of insufficient will affect the power
A: Insufficient power supply, first confirm that the wiring is correct, whether the power supply current is sufficient whether the power of the speaker itself is too small or too large, the speaker itself is poor bass performance, the structure of the speaker box, these abnormalities will lead to sound breaking!
