Power Supply for audio interface

Tanerfx · Sep 19, 2015

hey guys,

i got some old equipment for audio recording and well I had some serious issues with finding the right supply. The audio interface is called Marian: Ucon CX and yeah its quite old i think. So old that i cant find any original power supply cable. It needs "AC 8V / 1 A" supply and i recently bought a universal adapter which can either make 7,5V 1 A or 9V 1A..
so my question is what is better and should i even try this out??

Thanks for any replies.

It's likely that your universal adapter is DC, which probably won't work.

You need an AC output transformer, and they're starting to get pretty hard to find.

you should be able to find a 9V AC adapter on ebay cheap enough. there's a 99% chance the unit uses internal regulators to make +/- 5V rails for its audio circuitry anyways, so going from 8V to 9V shouldn't kill it.

here's an example: http

just be sure to NOT buy anything that has DC output. a quick red flag is that if the unit has this picture (+ and - with the round parts in the center) as part of the label, like the graphic in the middle. that indicates it's DC output and you don't want that.

Hi
In Europe doorbell transformers are usually 8Volt AC but if you are in the US they are 16Volt AC so if you are in the US you may be able to get a European one from EBay.

Someone Somewhere :

thanks for replying so fast. well it says ac/dc adapter so i think its capable of making both active and direct current

Tanerfx :

incorrect. what it DOES mean is that it takes your wall AC and converts it into DC for most small electronics to use, like chargers or digital scales or whatever.
