Power supply should be able to produce all the necessary voltages required by the digital and analog ICs.

Powered from a single 12VDC power supply
Supply for the analog circuitry:
- Dual rail +9V -9V
- 3V3 analog for
- Low noise as reasonable and be separate from digital supplies
Supply for microphones
- +48V Phantom Power
Supply for Digital
- IO power:
  - 3V3
  - 1V8
- Core power XMOS:
  - 0V9

Most of the design of the power supply will be based on my Analog Power Supply Prototype with a few key differences. When I designed that prototype I did not have the XMOS chip in mind, this means it is missing a 1.8V & 0.9V rails required by it.
