Description

Have you ever found strange noises jumping out of nowhere when using several pedals together?

The biggest reason that produces such annoying sound is that pedals are connected in a parallel mode. With such parallel connection each pedal forms a ground loop, which brings the noises from other magnetic fields into the signal path and all the other pedals are interfered and become unstable.

 

To solve this problem, all you need to do is to get rid of the ground loop issue, (isolation) & make sure each pedal works in an independent route, most importantly by choosing a power supply that considers this issue. Ideally a real independent output that is free from ground loop troubles. The JOYO JP-04 is an isolated power supply available for guitar pedals. It uses a high quality 'R' transformer.

It has seven 9V outputs, an additional output switchable between 12V and 18V and each with an independent power cable and ground wire, each output is completely isolated, complete with short-circuit and over current protection, it is by far a highly filtered and regulated power supply. This ensures a reliable operation, free from any hum or noise from your pedals.

 

DC Output 1-5: DC9V power output with the positive pole in the outer and the negative in the center. Each maximum output current is 100mA which is quite suitable for low power effect pedals. The output current is limited to 100mA and equipment with current consumption over this level should not be connected to Output 1-5. 

DC Output 6-7: DC9V power output with the positive pole in the outer and the negative in the center. Each maximum output current is 250mA which is quite suitable for high power effect pedals. The output current is limited to 250 mA and equipment with current consumption over this level should not be connected to Output 6-7. 

DC Output 8: DC12V/18V power output which can be alternated by the Switch button. The positive pole is in the outer and the negative in the center. The maximum output current is 100mA which is quite suitable for low power effect pedals. The output current is limited to 100 mA and equipment with current consumption over this level should not be connected to Output 8. 

DCUV/1SV Switch: This switch is designed to control Output 8. Turn the switch and point to 12V, the output of Output 8 is DC 12V. The same goes for DC 18V.
