Mini rectifier problem (grounding)

[spinlud]

Hi all guys!

Recently i have purchased a mini rectifier, and i am having problems when i play it in my box/studio where there isn't the grounding in the electric system...the sound lost a lot of attack, energy and punch, and the palmuting has crackles and frizzlings.

The mini rectifier sounds very good in my home, where there is the grounding in the electric system.

I want ask you if there is any solution for this problem in my box/studio to get the mini rectifier to sound right. Is there any device or electric filter that will solve the problem? Have you any solution or suggestion for this problem?

Thanks in advance for any help.

First, it's not safe to use the amp with no ground. Fix the grounding in the studio.

Second, it sounds like there is more of a problem than just bad grounding. The amp tone and dynamics shouldn't be noticeably different. I wonder if the line voltage is low.

Bottom line, fix the power source. No plug-in power conditioner will work without the ground.

Thanks fro the reply.

How i can test if the line voltage is low? What i need?

+1 Fix the ground issue. Not only are you risking your safety, the foundation of your studio depends on it.

Any standard voltage meter or DMM will tell you what the line voltage is.

Are you in the USA?

There are a variety of inexpensive line voltage testers available that you could plug into the line, that will give information about ground, polarity and voltage.

You can use a voltmeter or multimeter as Dom suggested, but be careful when probing. Use the one-hand rule: only use one hand. Put the other one in your pocket. (Keeps you from electrocuting yourself).

Or if you have a power conditioner, many of them have voltage indicators.

Remember that the amp's chassis is tied to GND. So is the shield of your guitar cable, and therefore your strings. If the ground is not connected, then the amp chassis could be either energized by neutral, which may electrocute you (neutral often floats a few Volts away from GND) or hot, which will surely electrocute you.

THanks guys for the precoius infos. In case i could fix the ground issue, wich power conditioner can i buy to have a good tension and current? I live in italy, do you have any product to suggest me?

thanks for the help!

A power conditioner will only clean up dirty power. To regulate line voltage coming in, you need a Voltage Regulator.

Thanks i got it. Something like this is ok? http://www.proel.com/proel/products...1069071796180/11195350157380&m=f#.UgNabpJM98E

Yes, that looks correct. What you want is something that will output a stable line voltage, no matter what the incoming voltage may be.

Ok thank you very much!
