Product details

SMSL A100 Bluetooth Infineon Class-D Stereo Amplifier

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.
