Vintech PSU question Channel Strips

Vintech PSU question

I just got an american Vintech X81 mic pre/EQ, with its external 110V PSU.
I'm in Europe and now I need a tension adapter to plug it to the 220V AC here.

I didn't got the manual with it so I don't know the specs.
Now I wonder how much power (number of Watts) does the PSU consume to have the channelstrip working at its best. Any ideas ? It should be written in the manual coming with Vintech gear.
Once i get this info, I can buy the correct tension adapter with the correct "maximum power".

Thanks a lot.

I asked the same question of Dallas. He replied:

Quote:
Hello Scott,
The maximum current output for the 24volt supply is about 1.2 amps. The 48 volt supply has a max current output of one half amp.
Thanks,
Dallas
I wanted to swap out the transformer so I don't have to schlep around an extra 110v to 220v transfo. Haven't gotten around to it.

This is pet peeve of mine: gear that doesn't switch between 100 and 220.dfegad

The PSU is really easy to modify to 220 ......

I will take a pic of the inside of mine

i think it was only soldering 2 bridges together...

it's often just a question of series/parallel with the primary which can be wired to a switch, which I've done with a lot of other gear since moving to Europe, but I haven't yet looked into this one.

Love to see the picthumbsup

Wow i'd be interested in this mod too. I was going to get a 110/220v power adapter tomorrow for my 473. Talk about timing!!!

here's a nice little diagram showing what's going on. Also, these Schurter switches are nice for adding this capability to gear - provided the transformer is designed to do this

based on the photo's you guys posted, I found this for the 24v supply:

and this for the 48v supply:
http://www.mpja.com/download/ip.pdf

Just standard International Power stuff, and it says right in the data sheet that it's good to go for 100-240v. have at it!

Time to get some qualified help then thumbsup. I'm not real big on giving advice over the internet about hacking expensive gear.heh I'd hate to have you blow something up based on my recommendation or even worse, electrocute yourself.

This should help you understand the jumpers...(from juniorhifikit's article )

I agree with getting help....

It might be worth asking in the geekslutz area for advice.... just link to this thread

OK I think I get the jumper concept. It seems you had to remove the jumper on 1&3 and 2&4 then put a jumper on 2&3. I'll seek help nonetheless. Thanks guys.

Here for the gear
 

Sorry to revieve this old thread, but i'm currently in the process of solving some power issues at my studio here in Copenhagen, Denmark - and a part of this is having my Vintech PSU reconfigured for 220/230v instead of 110/115 which is currently handled by a small 220>110 converter - less than ideal :(.

I came across this thread, and it seems all the information should needed should be right here, but the attached pictures / diagrams is sadly not displaying anymore.

Would someone kind care to elaborate or (re)post the diagrams necessary to do the required modifications for the psu to run off european 230/50hz current directly? It seems like a simple job, but without the diagrams i'm somewhat reluctant to take on this task ..

Hi

It would make more sense to contact Dallas at [email protected]

You could also ask him why he does not fit a voltage selector

heh

I'm having the same problem. I bought the X73i+PSU in the states, and I'm bringing it back to Norway. Will a 110 to 220 transformer make any difference to the sound, vs. fixing the problem internally in the PSU? I'm getting nervous about the fact that my X73i won't sound as good as it could have :S

It would be great if someone could take a picture of the inside of the psu and illustrate which wires to swap etc. !!!

Vintech do make a European spec PSU, specifically for the European market so no need to do any mods for the average user who bought their unit locally

If you bought a unit from the states than it will have a US supply but to be honest most 110-220V voltage transformers will be adequate as the Vintech's do not draw much current, and if you only have one unit connected its very low.

Vintech Audio PSU Problem

Hi Guys,

It`s not the same problem i try to solve but i hope anyone of you guys can help me

I have a x73 and x73 i with a european PSU and i have a 50-60hz Hum on the track i record. I tried another Preamp and then the hum is gone. It`s not a grounding issue. I also did cut anything else, just use my mac pro, Vintech x73 to apogee symphony.

Other preamps with the same chain, same cables do work fine

Does anybody have this problem??

Can`t use the preamps like this
