Hi,
I've been having this problem for a long time but it was occurring not frequent enough to push me into investigating solution.
I have M-Audio Profire 2626 audio interface on my workbench that I use for testing stuff I build. It's a 8in/8out firewire interface. Simple, nothing fancy...
This audio interface uses external small AC-DC power supply. This PSU is on the same wall plug (europe, 220vac) as all my other equipment. It's a bedroom in my apartment and I have only one wall plug in this room. Basically everything is on this plug. Can't change that.
Audio interface is connected to my computer with firewire.
Now the problem.
Every time I turn on the desk lamp, every time I turn on the unit I work on or whatever I turn on, I loose connection between my pc and audio interface! Cubase reports that it has lost driver and audio interface starts blinking LED stating that it has no connection. I guess that's some voltage drop or bump that causes this interface to loose power for a fraction of a section and it causes some sort of break in firewire connection.
What could be done?
It crossed my mind to add some large capacitors inside the audio interface right after the dc connector to smooth the voltage a bit, but I don't think there's space to fit those caps.
I don't have money to buy expensive power conditioners (furman and similar), and from what I've read those small office UPS units don't provide ac line filtering enough smooth for this kind of problem. After all, this is happening only with this audio interface. I've had other interface on my bench and it didn't behave like that.
Can anyone think of a simple fix for this?
