Topic: mono turns into stereo


My problem is:

I have:
- Fireface 400
- Cubase 4.5.2
- Logic 9.1.3
- OSX 10.6.4

I have a 5.1 surround setup.

My problem:
When assigning a mono channel to my front left speaker, (with a surround panner or mono output 1 or 2)  I get sound on the front right channel too (it also shows in the fireface mixer). The other way around the same.
The master levels in Logic or Cubase only show activity on the channel I want to see activity on.

This 'leaking' does not happen with the Lfe, Ls , Rs or the C channels.
When testing my speakers separately in the audio/midi-configuration of OSX there is no 'leaking' at all.

What am I doing wrong?

Greetings, Bas

Pan levels in total mix?

They are panned, so it must be something else.

deleting the driver does not help
If I try it on my laptop --> no problem
