Latest revision as of 19:09, 19 December 2022

A good clean power supply unit (PSU) is the most important part of a modular system. A proper linear power supply and good distribution makes a big difference to the stability and sound quality of the system.[1] Switch-mode power supplies are smaller, lighter, and much more efficient than linear power supplies but produce more noise, (above audio range) on their output.[2]

Safety

Use a RCD. Mains voltages can kill and capacitors in disconnected power supplies can still deliver quite a jolt. Unless you're qualified to work with mains electricity, ready made external transformers are safer.

Notes

  1. ^ Trying to decide what's linear or switching, the transformers are mostly interchangeable so instead going by the type of regulators.
