Feature
1. This board is specially designed for home and car 2.1 systems. With passive 2.1 speakers, it can get shocking and lifelike live effects, and it can also achieve high-fidelity 2.0 HIFI music playback.
2. The core of the board is super quiet, but because this board does not have a shell, good power and signal lines are essential. It is best to wear the knob or connect to the signal ground, otherwise the direct touch of the board or potentiometer will induce interference sound.
3. 95% of the people said that the power is enough, and 5% of the people are not enough for the standard power. Please check the power of the power supply in your hand. If you only have a 12V 2A power supply board, the evaluation that you get is definitely insufficient. 12X2A=24W. The power supply is not strong, and the power amplifier cannot output enough energy. Remember, it is recommended to get enough power and the power supply must be 16V 4.7 or above
Function
1. The total capacity of the capacitor is increased to close to 10000UF (4700UFX2), which can make the signal-to-noise ratio better, the low frequency strength is good, and the energy source is continuous.
2. Rich adjustment options, adjustable subwoofer frequency, adjustable left and right channel high and low sounds.
3. Redesigned low-pass filter, stronger subwoofer thrust
4. Fever low loss red ring inductor output
5. 4 pieces of NE5532 fever operational amplifier is the current stage, low-pass and other amplification
6. No external power supply, laptop power supply can be used.
7. Power supply:DC12-25V
8. Interface:outer diameter 5.5MM inner diameter 2.5MM
9. Power:2X50W+100W subwoofer (tested under DC24V)
10. Circuit board size:95x150MM
The main technical parameters
The output power is different under different voltages
Operating voltage range:DC 9-25V (current 3-4A or more, if you need more power, it is recommended to 19-24V/4-5A or more)
Audio input sensitivity:500-800mV, frequency response range:20Hz-20KHz
Speaker impedance:Left and right channel speakers:3.5-8┯, bass speaker impedance:2-8┯
Maximum output power:50W (left channel) + 50W (right channel) + 100W (bass channel)
Operation notes
Before turning on, turn the knob to the far left, and then turn on the input DC power supply, so that the boot is completely shockless
Do not directly unplug the input DC power supply when shutting down, but first turn the volume knob to the lowest level and then unplug the DC power supply. This will make the shutdown without any impact
The power connection light on the leftmost side of the board is always on and is not controlled by the switch.
Package includes
1 x Power Amplifier Board
