SMSL offers with the A100 a compact and affordable but nevertheless powerful Class-D amplifier, based on an Infineon MA12070 chip allowing it to develop 2x80W under 4Ω. Simple and efficient, the A100 is simple to use and practical. It integrates what's more a Bluetooth 5.0 reception allowing to broadcast its music remotely, directly from a smartphone or a tablet.

The Class-D amplification stage of the A100 is based on an Infineon MA12070 chip, offering a good energy reserve while ensuring a clear and faithful reproduction. This one takes advantage of the MERUS architecture, in which each half-bridge uses four MOSFETS.

In addition to its stereo RCA and USB-A input, the A100 embeds a Bluetooth 5.0 receiver allowing you to broadcast your music from a distance, from a connected smartphone for example. The integrated chip supports the aptX transmission codec ensuring very good audio quality and signal stability. In addition to the classic speaker output, the A100 is equipped with a subwoofer output on stereo RCA. It is thus possible to connect an active subwoofer and thus integrate a 2.1 system.

Customer Reviews (4.4 / 5 · 5 reviews)

Edward Q. ★★★★★

I was skeptical about how clean the sound would be from a compact amp, but running my 4-ohm towers through the Infineon MA12070 chip delivers surprisingly detailed highs and tight bass. Perfect for a desk setup where space is tight.

Miles X. ★★★★★

The Infineon chip really delivers—my 6-ohm bookshelves get loud and tight with zero hiss, even at low volumes from my phone’s Bluetooth. Connected instantly and it’s stayed rock-solid for two weeks of daily use. For the price, this little amp punches way above its class.

Jason ★★★★☆

The Infineon chip really pulls its weight—cranked it to about 60% on my 4Ω bookshelves and it stayed clean, no harshness at all. Setup was dead simple too, just plug in and go. Only wish the case felt a bit more solid for the price, but the power you get is hard to argue with.
