Adam link is a small and very flat power supply for effect pedals with 4 isolated outlets. Being only 31mm high, it fits under the smallest Pedaltrain models PT-nano or PT-mini.It offers voltages 9 or 12V and a total output current of 700mA. The top two fixed 9V outlets will power any two Strymon or or other two medium current pedals. The bottom two outlets, configurable to either 9 or 12V, will power two or even more standard low current pedals when used with Split Flex or 3-way daisy chain. If needed, all 4 isolated outlets will give you 9V DC in the default position of the settings switch.
