With the Audiophonics MA-S40 we offer you a compact Class D amplifier, based on an Infineon MA12040 amplifier chip. This one allows it to develop a power of 2x30W under 4Ω while taking advantage of a high efficiency and a very low distortion level for a clear and detailed sound. Its architecture uses a multi-level half-bridge power supply stage. Each half-bridge is equipped with four MOSFETs.

The MA12040 chip incorporates an intelligent digital management protocol and a thermal, short circuit and undervoltage protection system.

Conveniently, the audio input is Bluetooth 5.0, thanks to a QCC3003 receiver chip and an antenna for excellent signal stability. It is therefore possible to play music directly from a smartphone or any other connected device, or by using the 3.5mm jack input on the front. Finally, the output is made directly on speaker terminals at the back of the device.
