Digitally Controlled Audio Mixer Input Board

### DESCRIPTION ( Introduce yourself and your project)

I am a hungarian student and electrical hobbyist with several years of experience and I want to build a digitally controlled audio mixer. I don't have much money to buy a commercial digital mixer, but want the ability to control audio by a console and on phone too.

### TECHNICAL DETAILS (With project photos)

The input board contains an STM8S003F3 to control the BD37534FS, which is the volume and tone control ic. Every conponent except the connectors are smd, the pin headers on the sides are for linking multiple boards to have more inputs, and the pin headers on top and bottom provide interfacing options like vu meter and aux input.

I will only start designing output boards when this board has proven to be good. It will contain an STM32 type MCU and an ESP 8266 wifi controller.

The case will also contain several power amplifiers, which I will buy from eBay.

I plan to make a small mixing console with most of controls, it will only require an UTP cable (or WIFI) to communicate with the main unit, The communication on the UTP cable would be RS485 because of its simplicity and reliability. Power and headphone signal can be sent on the cable too. The console would have few 18650 batteries to operate wirelessly.
