Donner DP-1 Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal.

Switch For LED Lights
Turn the switch towards those LED lights, normally all lights would go on after the power is connected. If you don't want all LED lights, please turn the switch back.

Independent and stable power supply
The power supplies of the Donner series of effects have absolutely independent power interfaces. It has an 18V power supply, and all outputs are independent of each other through its voltage regulator circuit. The aluminum alloy material is strong and compact and easy to carry.

Short-Circuit Protection
All 10 outputs in this unit have separate short-circuit protection, i.e. short circuit in one channel won't affect other channels' function. Under the circumstances of all LED lights on, LED light of the short-circuited channel will off, while lights in the other normal channels are still on. This helps locating the faults when there were short circuits among many effectors.
