How to reset the digitech vocalist live 4 harmonizer?

Sounds like the mic you are using requires "Phantom Power." This means, you will likely have to purchase an external unit for this power (+48V) power to the unit. I use a Behringer Ultra-Voice Pro for mine. Works great!! You can find these on Ebay at a steal!

The only guitar amp that has 2 female jacks, one xlr and one 1/4" is a tall Acoustisonic anp by Fender . I have one and I use the Vocalist 3 and I still have an instrument jack for my acoustic guitar . hope this helps .

U.S and Canada: 20 VAC, 60 Hz Adapter: PS093B-20
Japan: 00 VAC, 50/60 Hz Adapter: PS093B-00
Europe: 230 VAC, 50 Hz Adapter: PS093B-230
UK: 240 VAC, 50 Hz Adapter: PS093B-240

Power adapter requirement straight from the user manual. I am sure you are aware that a simple plug adapter in a tourist shop does nothing to convert 120v US to 240v AUS. Note you unit does not like temperatures above 40C. And you can get that in Australia.

Bear in mind the timezone difference if you try Digitech support in the US.

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.

Hi there,
What mixer will you be using it with and how many channels will you need to use it on. After I know this info I can help you.
Thanks

First check that you are using the correct power adapter.

Of course you can. I would send rather simple voices to the vocalist from the keyboard rather than really wierd sounds as the vocalist has to analyze the sounds to decide on creating the harmony from your voice. They do say it can be used with keyboards in the literaturee.

Make sure the replacement power supply was EXACT same ratings and polarity.

you may have a bad cord. try others. all so try reversing the polarity on the back of the amp. DFD
