## Electrical Design
See [electrical-design.md](electrical-design.md).

Components marked as DNP (do not populate) are needed and need to be added.
The mark is just to generate the right BOM for ordering an assembled PBC with all SMD components, but no though-hole parts.


## User Interface
The user interface should enable the interpreters to adjust their microphone gain and headphone mix on their own.

Line level in professional audio gear is at +4 dBu, which is 1.228 V (RMS).
Because 0 dBu is defined as 1 mW at a load of 600 Ohm, which needs a voltage of 0.77 V.
Increasing the voltage by a factor of 10 is an amplification of 20 dB.



## BoM
All prices without VAT and for one piece unless otherwise noted, even if the BOM already asks for more.
So it's expected to get lower when ordering a full set for multiple units.

#### Line I/O Board Components
BOM for one PCB, needed 1x for whole assembly.
Electrolytic capacitors should have 25 V voltage rating, unless otherwise specified.
