Today, we’re going to talk about power supplies - why choosing the right one is important. ⠀
A power supply supplies the necessary electrical power to each individual pedal on your pedalboard. It is important that each pedal receives the correct amount about voltage and current in order to prevent damage to the pedal.⠀
Linear analog power supplies, such as the Voodoo Lab Pedal Power series, are 100% analog and use toroidal transformers to provide *isolated* power to each pedal. These tend to weigh more and have a larger footprint.⠀
The switching power supply, such as the True CS12, Cioks DC7, Strymon Zuma/Ojai, are much more efficient. These are not analog - they use high frequencies to provide isolated power to each pedal via transformers. These are able to provide more power than a standard analog power supply, and are less sensitive to noise interference with digital pedals.
When choosing a power supply, it is important to ensure that it will provide each of your pedals with their required voltage AND current. For example, a Boss Digital Delay DD-7 requires 9 volts (voltage) and 55 milliamps (mA) (voltage). In all power supplies, each individual output has its own voltage and current limit. Pay proper attention to which output you are connecting your pedal(s) to, to prevent damaging your pedal(s).⠀
Accessories you can purchase to ensure you provide the right amount of power to your pedals include current doublers, voltage doublers, reverse polarity, etc. Avoid using daisy chains, as they can introduce unwanted noise into your signal chain. Use isolated power whenever possible!⠀
