The design target of this project is to create a PCB which can be mounted in a stereo audio power amplifier for professional applications, allowing to remotely change the volume via a web interface. It further allows a few other basic settings of the amplifier, and also the display of the basic amplifier status via the web interface. The signal path of the amplifier remains analog, hence a digital potentiometer IC is used for the volume control. The user interface consists of two encoders and 18 LEDs. Connectivity encompasses a USB port to make initial IP address and unit name settings, and the Ethernet port for the remote access.
The web interface must be realized by an embedded webserver to avoid future application update necessities.
The project is budget-sensitive, the hardware is supposed to range in the sub-5 USD range. STM32 MCU would be preferred as the core engine due to supply chain reasons.
