Assembly Audio System ( ASSM AUDIO) - Project 1

We propose a new concept audio system, It is an audio system with slots for inserting function units in one main body. It is a group for producing the first product for standardization. (Network audio player, DDC, DAC, PHONO equalizer, PRE Amplifier, POWER Amplifier, POWER SUPPLY, etc.) The internal main board has slots for inserting the unit, and the corresponding unit can be installed and replaced with another compatible unit. Function units are made in card format and can be upgraded or replaced with other branded products in the future. You can choose not to install them selectively, but you can install them later. Units are less costly than single-unit audio equipment because there is no case, and the finished product is very low in price. Each unit is unique in many vendors, can be upgraded to new units, is compact, has only the necessary functions, and is easy to use.The original written in Korean has been included.This is a measure to prevent errors from occurring in the PCB design file (Kicad) when creating the BOM file.After downloading the Kicad file, make sure that there are no spaces in the file name and directory name that contains the Kicad file. Please change the space of downloaded file name to - or _.
