Hi, I want to buy an amplifier that is for american market and so it need different current voltage. Does it exist a current converter? Cheap? and after all it sound good as normal the amplifier?
thank you
thank you
how can it, when even powercords are claimed to have a sound.
Otherwise, if the sound of transformers doesn't bother you - make sure you get a converter approbriate to the max. wattage used by the amp.

thank you
No I'm not of that party. Infact I see that even audiophile brands such NAD or AMC use very normal and thick power cords.
Do you mean the sound of the external transformer, right? because With all that energy there shouldn't be some fans?
On the spec sheet of the amp:
Power consumation 360W so what converter I need to have "full power" also at high volume? 360w is ok or I need some reserve?

Do a google search for "1000W autotransformer" which is all you need with a very large safety factor.
you should be able to source one for €100 or so, eg

An autotransfor is a lot cheaper since it only has one winding with taps on it (0-110v-120v-220v-240v etc)
So you would connect your (italian?) 230v between 0 and 230v, and the amplifer between 0 and 120v

Hi,
wait till you can get inside.
The transformer may have a dual primary that can be rewired to take various voltages from 110Vac upto 240Vac.
If the transformer has only a single low voltage primary, then you have a choice
1. change the transformer to a 230Vac version with all the correct secondary tappings and windings (could be expensive).
or
2. fit an external transformer to convert your 230Vac down to 110 or 120Vac to suit the maximum amplifier input power.
An autoformer is cheaper and technically just as good if you go for an external conversion.
An isolating transformer offers the advantage of isolating your amplifier from the mains and eliminates one of the routes for mains hum (earth loop). The portable 230Vac to 55-0-55Vac safety transformers used on building sites would give what you need and relatively cheaply (do you have these in Italy?).

yes we have but they aren't so cheap.
If I don't use isolation transformer I get hum from my speaker or from something?
or it's just the normal noise on the current line that I get today? I hate hum
Explain me well, it's cheap and easy to do?

Hi,
WAIT!!!!!!!!
Check inside and see if it is fitted with a dual primary transformer.
If it is then call back and we can explain the easy conversion.
(just hope it's not as confusing as a recent KRELL thread - they go out of their way to prevent conversion)

and you have it open today!testarossa2k @10.42 pm yesterday said:
I think I see four wires from the mains side.
This COULD be a dual primary transformer.
Hi,
post a bigger pic of the mains input to the transformer.
Read off the labelling that could give us some clues.

I don't have the amplifier. I just want to know what I have to do to understand if it's an easy work. Because if it isn't I take a onther model of amplifier here in europe.
I have just to change wire connection or I have to change also the fuse?

Hi
You will have to do both. Since in America they use 120v you will need 2x bigger fuse for same power. Changing fuse really can't be too difficult.

Hi,
if the transformer has a dual primary that is 120/240Vac compatible, then the changeover is easy.
If it has a single 120Vac primary, then you need to feed in 120Vac.

But how do I know before actually buying it that it has dual primary?
I ask you because if it hasn't the saving cost of buying that amplifier isn't much if I have to buy an external transformer.
I forgot to say, it's an AMC 2100 power amplifier. Don't know if it helps...
