NO Bluetooth = $20

Bluetooth 5.0 QCC3003+Decode PCM5102A=$28
Bluetooth 5.0 QCC3034+Decode PCM5102A=$30


If bluetooth prompts for a PIN code, or password pairing, it’s usually: 0123 or 0000 or 1234


Bluetooth 5.0 has added independent decoding, among which the upgraded chip USES Qualcomm QCC3034, the classic chip is QCC3003, the decoding chip USES PCM5102A decoding, sound quality is very good.
Especially the upgraded version,Bluetooth USES the latest generation QCC3034 and supports it
24BIT bluetooth aptx-hd format, analysis power is still above CSR8675

Because the use of close to 10000UF total filter capacitor, 6 oxygen-free copper output inductors, gold-plated input and a series of high-end components, 4 NE5532 prices will be slightly higher than similar products, but the sound quality is completed is proportional.

This digital power amplifier board for notebook switching power supply and 12V-24V ordinary battery direct power supply, Home and car amplifier are suitable for use, is very convenient.


Operating voltage range: DC 9-25V (current 3-4A or more, if the power of the larger recommended 19-24V / 4-5A above),
Audio input Sensitivity: 500-800mV,Audio input Sensitivity: 500-800mV,
Frequency response range: 20Hz-20KHz,
Speaker impedance: left and right channel Speaker: 3.5-8 OHM, Subwoofer Impedance: 2-8 OHM,
Maximum output power: 50W (left channel) + 50W (right channel) + 100W (bass channel),

Upgrade version, the use of materials more fever level:

1 capacitor total capacity up to close to 10000UF (4700UFX2), this can make the signal to noise ratio is better, low frequency strength is good, steady stream of energy.

2 rich adjustment options, subwoofer frequency adjustable, left and right channel bass adjustable

3 redesigned low pass filter, subwoofer thrust stronger

4 fever low loss red ring inductance output

5 4 NE5532 fever operation play before the level, low-pass and so on

No external power supply, you can use the notebook power.

Power supply: DC12-25V

Interface: Outer diameter 5.5MM, inner diameter 2.5MM

Board size: 95x150MM
NET Weight:170g/164g/160g/150g

Different output power is not the same voltage

Operation Notes:

Before turning on the knob, turn the knob to the far left, and then turn on the input DC power, so you can make the boot completely no impact

Shutdown Do not directly pull out the input DC power, but first turn the volume knob to the left and then pull out the DC power, so you can turn off without any impact

The left side of the board power access lights, often bright, not controlled by the switch.

    Использовал в детской машинке. В сравнении с нормальным автоусилителем низкие частоты немного бубнят. в целом играет хорошо
