[smooze]Cellphone stupidity...

I don't know where you live, in France, but all female family members are for a long weekend in Paris, this moment.

My wife phoned me asking: "You never guess where I am at the moment!"
"Top of the Eifel tower?"
"How do you know?"

Hi guys, i recently bought a used nordlead 2x, i'm having a problem with the device, this synth was buy on Australia a couple of years ago, so as a result the power of the synth it's intented for 230V

According to the tutorials i've checked, about the fuse and the voltage changes needed i have previously done the switch procedure to 115V inside the synth, also i checked the fuse and it looks like it's not properly for this amount of voltage the fuse shows 250V, could it be possible the problem?

The synth right now turns on, shows lights, sends midi messages, and receives midi messages, the pitch works fine, the wheel works fine, and the problem appears when you play any sound preset or program on the keys it makes a kind of loud white noise sound which results on the imposibility to use it, does somebody have had some type of problem like this before? could it possibly be the fuse? Confused

Here are the pictures of the synth:

It's hard to tell what's wrong, although I know some musicians who would love this sound...

Electronic devices are sensitive to the right power supply. First I would change the fuse!

When the problem isn't solved try the different Outputs. It could have broken DAC's. This can be repaired by a service station.

Thank you Wout, i will try out with the fuse, i hope it solves the problem, anyway i will be posting my results.

So, i'm in Brazil, and my Nord Rack 2x was set to 115v and i plugged in a 220v plug...

Since the majority of plugs here are 115v, i had already done this on a gig in another city, but only the fuse was blown. This time i already changed it and it was not only the fuse, so i took it to an electrician friend just to see if he can find the problem. He tested everything and the problem apparently is only on the "trafo" (don't know exactly how i say that in english, but since it has "DANSTRAFO DT14275-1" written on the side, i guess it may be similar).

I have gigs scheduled, so i'm in some kind of hurry, but i want to fix it perfectly instead of trying anything wrong.

Don't know if Clavia have some representation/service center in Brazil, since i bought this from a guy on ebay. I didn't found this info on their site too. I'm going to São Paulo to a gig next week, and i'm certain that if they have service centers for clavia in Brazil it has to be on São Paulo...

Anyway, anyone (Wout? heh) can tell me something about retail in Brazil and about the "Trafo" specifications so i could buy another one there?

Thanks guys, i'm really worried about it.

Either a fuse is good or it is blown. If the fuse is blown the unit will not boot or operate or do anything whatsoever (except for providing an attractive color accent that will warm up any room's decor).

Wout's MOST excellent posts in this thread provide complete documentation of most aspects of the 115v/230v issue. US market units now ship with 300mA fuses and service documents specify that rating.
I have listened to that noise file and feel confident in saying that changing the fuse on that instrument will NOT fix that problem. I'm also glad to say that although I too know musicians who would like that sound, I don't have to work with any of them. Wink

As a general reference, Clavia's distributor's will almost certainly know the best Nord service techs in any given country. And the forum at large can spare Wout much typing by surfing Clavia's website to this link:

http://www.nordkeyboards.com/main.asp?tm=Distributors

and getting contact info there. Rod, I see already that there is no Nord distributor in Guatemala, but you might check to see what else might be closer to you than USA to save shipping costs.

The US Nord repair HQ is in Tampa, Florida, where I also serve as Clavia's tech support rep in the US. I do not wish to solicit business in this forum, but am able and willing to assist Nord owners in need through my regular work email: nord@proaudioe.com.

Sam, if you are unable to find what you need in Sao Paolo, let me know.

Not sure why you say, Wout, that Clavia doesn't repair broken units, because I personally know of several instances within recent months where PCBs have been shipped there from all over the globe for component-level work. You've been around for years and I'm new around Nordland, so perhaps this is a more recent development?

Bless,

Pablo

I never said Clavia doesn't repair, they surely do! Only not the one which was send in: they make an exchange and repair the broken one later.
Maybe they send these to the service centres? After all, Asogatan Stockholm doesn't have that much space...
And the parts are needed all over the world.

Thanks for this thread! I changed the voltage on my stage 2 yesterday, and they've added a metal cage around the switch. We attempted to remove the cage but it's like they've glued the screws on or something. Anyway, the switch was easily reachable through the cage. I will attempt to attach a picture to show this.

Thanks again for posting all that information. It was so helpful!

It's obvious Clavia build the case to reduce the power supply hum Smile

The switch is the red thing reading 23(0), I assume...

Nice to be at help here.

My synth got fixed i changed the whole motherboard for a new one, now it sounds awesome, Mr. Pablo Mastodon really provided me with all the costumer support i needed and more than i expected, thanks!

I'm not experiencing that hum noise, even do i changed the fuse andit works perfect ... or maybe i'm deaf Shocked

well i guess i'm going to leave it like that.

@ rodv Nice Pablo did a good job. It's what Clavia and distributors are well known for!

Hi,

trying to solve this problem the 'old-fashioned' way (i.e. with a voltage converter) and having some problems...looks like there is a lot of expertise here so hoping someone might have a suggestion.

I have US manufactured (115V) Nord Lead 2 that I am trying to use in the UK. I purchased a 200VA step-down voltage converter rated for devices of up to 200W, which should be more than enough -- certainly it works fine for my 110V Sherman Filterbank and Waldorf Microwave (rated 500mA and 1000mA respectively).

The problem is that power cycling the unit seem to blow the fuse. So I insert a new (250mA) fuse, depress the power button, unit functions, depress the power button again, unit shuts down, depress the power button a third time, fuse blows. For a while I got around this by leaving the power button depressed and pulling the power cable physically out of the voltage converter -- but even this doesn't seem to work consistently, and now I've blown my last fuse.

In addition to being frustrating, this clearly can't be safe for the unit -- but I can't understand why it's happening. Is the 200W transformer simply insufficient for the NL2? (I can't find mA rating for the NL2 anywhere, but all my other synth gear is rated at 1.2 mA or less.) I thought I might have to switch fuses, but since it's still actually getting 110V, it should still take 250mA fuses, not 125mA ones. Unfortunately changing the setting on the board directly isn't an option as I really need to be able to use the unit in both 110 and 220 regions.

Thanks!

I believe the power consuming force of a NL2 is around 13 Watt.
What tells the number on the back side?
Older versions only take 200mA fuses...

So yours is from early 2000 something.
Should take 250mA fuses.
Better contact the British distributor by phone, not by the support site, because you probably have bought the synth in the USA.

Could be some trouble in the power supply.
