Lm3886 is in semi Overture Series in the highest model, the voice was warm and charming, low-frequency plump, resistant to natural and actual audition than tda7293 very small. At full power, tda7293 distortion to be several times larger than the lm3886.
At present 2. 1 of the board are available, index of digital power amplifier and scary, 100W 200W but it is Euro 4 indicators, go into 8 ohms, reduce power of one and a half, now of 150W subwoofer is equal to the digital power amplifier of 300W the has in the 8 ohm resistance, listening is far better than.
Then cheap 2.1 is LM1875 2030A, but the power is small, the output of the poor 4A current, so that the bass does not burst up. , LM3886 output up to 10A
* * *The use of 4 new original LM3886 chip, to provide a strong output of 68WX2 180WX1, far more than the digital power amplifier 200W.
* * *Dual Japanese OMRON protection circuit, so that the expensive sound box work in a safe state, the switch is also no impact,
* * *The operational amplifier with low pass circuit, elements can be replaced, the low-pass cut-off frequency is adjustable, very professional
* * *Excellent material, catch 718 feet of copper resistance, the German WIMA ERO ELNA Brown God RC elements have a fever.
* * * high power oxygen free copper ring transformer power supply, the British NOVER capacitor filter
External dimension width: 190mm high: 70mm length: 311mm
The wind LM3886 BA1 2.1 channel bass amplifier will be added to the follow-up
Taiwan high quality step potentiometer
Dual Japanese OMRON protection circuit, so that the expensive sound box work in a safe state, the switch is also no impact,
This is specifically designed for low pass filters
In half genuine new LM3886 really see this is the new mainstream
Can choose the Japanese chemical capacitor or the British NOVER capacitor
