README
README.mdMultimedia center with DAB/FM radio
Features:
High quality (IMO) pre-amp board with I2C control of inputs and VCA based volume control.
5 line inputs, one may be fitted with an internal RIAA-preamp (phono, for moving magnet cartridges). 2 line outputs with old-style tape copy function and post listening possible.
Power amplifier on/off switching via inbuilt relay river.
KeyStone DAB/FM-module may be fitted.
Custom Raspberry PI power switch with PC-style startup/shutdown, may be controlled over I2C or from a front panel button. Has "breakout" socket for internal USB HDD.
IR Remote Control - RC5 protocol: for input selection, volume control and UI controller navigation.
Main controller built around a Texas Instruments Tiva C MPU, custom UI library with support for KeyStone radio-module.
Raspberry PI for media playback (via Kodi), in my configuration audio is fed via HDMI to a TV and then to a DAC mounted inside the pre-amp cabinet.

Questions
How big is the Controller PCB?
It measures 75 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
61 parts, built around the TM4C1231H6PMI, AT42QT1011-MAH, AT42QT1012-MAH and LM358. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Controller KiCad files?
From the terjeio/MultimediaCenter repository on GitHub, at the commit this page was made from: the board is Electronics/Controller/controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask terjeio before reusing the design.
