Stereo Power Amplifier Module LM3886 2x68W / 4 Ohm

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.

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.

excellent ampli
le lm 3886 est un tres bon petit audiophile moi je l'ai monté avec un dip 8 de chez jrc 5534m et la le résultat est tanscendé je possede encorre ce montage et je m'en lasse pas écoute pleine d"aeration basses profondes et percutantes medium clair image sonore tres charpenté et ample il faut juste le me modifier un peu je lécoute avec des enceintes fostex tres haut de gamme que j"ai monté moi meme le résultat est divin
