Infineon MA12070

MA12070 adopts a new power amplifier architec-ture MERUS, which is completely different from the traditional class D power amplifier. In this design, each half-bridge uses four mosfets(M1-M4), and the capacitor "flying" between them as an additional power supply rail, thereby generating a three-level output signal at the output switch node.

Built-in Bluetooth 5.0

Supports apt-X and AAC, Using Qualcomm's modular Bluetooth solution, built-in Bluetooth antenna, signal stability and transmission quality have been improved in all directions. Let HiFi push towards wireless.

Driver-free USB input design

The accessory provides a USBcable dedicated for A100, which can be directly plugged into the computer to play songs. It supports multiple formats of music files. MP3, SBC, WAV and FLAC can be played easily.

Sturdy and secure
It took a few tries to get it positioned exactly as i wanted it but once that was done it hasn't moved. I have a Samsung s25fe phone with a case and it fits just fine. Seems secure. It does shake slightly while driving on bumpy roads but it doesn't move positions and I don't feel like my phone is going to fall. So far it's been great.

Quality cell phone mount.
The best cell phone mount I ever used. Quality is obvious after you easily install. This hasn’t moved since I placed it in my car. I like that it doesn’t block the air vent too. (You can move any angle you like). Won’t disappoint! Good buy!

Good product.
This works well. It's sturdy and holds the phone well. It does keep the vent from adjusting but not a big deal.
