Stereo amplifier module LM3886

2x68W 4 Ohm

module amplificateur stéréo

LM3886 + AOP NE5532D

This amplification module integrates 2 LM3886 amplification chips in Class AB, coupled to 2 AOP NE5532D mounted on DIP8. With these components, the amplifier is capable of delivering 2x68W to efficiently power your audio system.

Dynamic Feedback & pure DC amplification

This amplifier module incorporates a Dynamic Feedback design. This method allows it to significantly reduce distortion while improving the signal-to-noise ratio and providing warmer sound.

To ensure true separation, each channel uses a high-gain Op Amp. This architecture results in deeper bass and dynamic high frequencies.

Speaker protection & Balanced XLR

The module integrates a loudspeaker protection circuit using an Omron UPC1237 relay. Your high-end speakers have nothing to worry about with this amplifier.

The XLR interface has a symmetrical structure. This one, recognized in the world of the audio, allows in particular a reduction of the noise and distortion for an optimal restitution.

Quality components

Each module integrates high quality components, contributing to the sound quality of the product. For example, there are ELNA, Nover, Panasonic FC capacitors or an Omron relay.

Mediocre amplifier board
First boards to arrive were missing components, but thanks to Audiophonics' good support, I was quickly sent new boards. The boards suited well for my project and they sounded decent. The layout and build quality of the PCB is good and most of the parts were genuine parts, altho some regulators seemed to be refurbished. Also I would have wished that more data about the boards had been sent with them. (Testing results etc.) The boards were in a lot of use for about a year, until on the other board, the relay for selecting signal input, died. For the price they are decent amplifiers,

Very good version of the LM3886
First pair of the amplifier boards I ordered were broken out of the box and I had to send the boards back. Despite the inconvenience, Audiophonics replied kindly and took quick action on replacing the boards. Thankyou for the excellent support! I've had the amplifier boards in use now for half a year and they sound awesome. bursting some real power out of them has never been a problem, since the board is well designed and has good fail safe mechanisms. Only improvement I can think of would be a rigid packaging for safer transport and some kind of note containing the boards information and hardware requirements.
