I hav a digitech rp500 and my power adapter broke and i bought a universal adapter and it powered the pedal but it wont make any sounds, someone help me

Consult the manual for the rating of each power adapter to compare. The units will also have the specs needed printed next to the power input jack, but the manuals will be more detailed.

Usually the manuf. have diodes used as protection against over voltage or adapter polarity issues. Try the correct adapter (sleeve and tip have specific voltage polarity...check for drawing denoting each) and if it fails to power the unit up, it's probably time for Digitech authorized repair.

HEY THERE! I have had similar problems with digitech pedals before. Follow these steps and if the problem is fixable you should be able to identify and correct it.
First identify where the actual problem is. These steps are basically just a "process of elimination" troubleshooting method. This method works for almost any problem with electronics.


1.Plug cable direct to amp from guitar. Have sound? If so its not cable repeat this step with the other cable. Good?

2.If both cable are working plug direct to pedal and use headphones to see if you hear anything. If there is sound it is the output jack.

3.If you still don't hear anything turn on the metranome or "rhythm button and crank the volume ALL the way UP. If you faintly hear a click then it is definitely a power supply issue. Be sure that the AC adapter you are using is 9V and at LEAST 1300mA. I know from experience if the milliAmps are lower than that it will work but not draw enough power to output any sound.
(If you have an old Nintendo system that power supply will work)

4.If a new power supply is used and all other options don't work the pedal is probably broke....I would try a factory reset just to be sure it is not a setting you bumped or something.
HOPE THIS HELPS! Good Luck!

Make sure you have the OFFICIAL Digitech power adapter. Universal adapters or those for MOST other pedals will NOT work... things may light up but you will NOT get audio. This unit requires an adapter supplying 9 VAC (not DC) at about 1 amp. These AC output adapters are not very common and people get the units without an adapter and try using universal adapters and they do not work. An AC adapter is used by Digitech so they can generate both plus and minus voltages internally. I don't know what your utility power voltage is in Cebu, so you need to get an adapter for your voltage that will give 9 VAC output and fit the power jack on the unit.

You CANNOT use the Voodoo as it outputs DC voltage and the EX-7 requires an AC voltage and of 9 VAC and also 1.3 amps at that.

A common problem is that somebody has paired the WRONG power adapter to this unit.

The REQUIRED adapter should be 9VAC (not DC) at 1300ma or 1.3 amps.

Note that UNIVERSAL replacement adapters will NOT work with the Vocalist.

All DigiTech expression pedals use an optical system instead of potentiometers.

Either the light is broke, or the filter.

The filter protrudes from the bottom of the pedal, and is darker at the top and gradually fades to clear at the bottom. If this breaks off, then there's nothing to limit the amount of light to the optical system.

If it is the light, then you'll have to have it serviced by someone qualified to work on it. Your local music shop should be able to help you out.


Hope that helps!

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/cameron_463100ffd54b591d

NO power light or audio from Digitech Vocalist 2 live. Check that your power adapter is for 9 Volts AC (not DC like most pedals) and is rated at 1300ma or more. A DC adapter MAY light up the unit but not make it pass audio. Lights can be lit but that is NOT an indication thaat correct power is applied. They likely use the AC input to generate both positive and negative voltage within the unit. The use of a DC adapter will prevent generating one of these required voltages and prevent audio from passing.

Check that your power adapter is for 9 Volts AC (not DC like most pedals) and is rated at 1300ma or more.

Try contacting their service center rep at (801)566-8800. They might send you a schematic for the pedal if you explain your situation. They do recommend using the original power supply PS0912 which should still be available. Hope this helps.
