Help with a patchbay

[franz]

Wow!
You're assumption was right, I'm running in stereo!
I think that you'er right whe you sayin that the phonic or the headphone amp could be superlfuous.
I am goin to try you're suggestions this week-end!

I will keep you updated!

Let me know how it works, and what I've won
That had to be a question from the "win an afternoon with Vangelis" contest
Cheers, Hanon

Problem... I hear from one channel only! I followed your instructions carefully and I checked my cables, but I still hear from one channel only. Any idea?

is the ha4700 in stereo mode or 2ch mode?
should be in stereo mode.

The Powerplay is in stereo mode

The Powerplay is in stereo mode

As a diagnostic procedure, I would determine which signal output of the stereo pair that is missing, then plug the headphones into the mixer to see if both signals appear there, then back track towards the instrument(s) to find the bad connection(s).
Are you using unbalanced (TS) or Balanced (TRS) cable connections?

If I plug the headphones into the mixer I hear the Nord and the Montif correctly in stereo.
I'm using unbalanced cables.

Thanks for help

The problem has to be one of the following connections:

The Mixer Main Output Left to patchbay connection 7A Rear "Split Configuration Mode 3".
The Mixer Main Output Right to patchbay connection 8A Rear "Split Configuration Mode 3"

The Keyboards mix will be found at:
7A Front {Possible keys Left mix to monitors}
8A Front {Possible keys Right mix to monitors}
7B Rear {to Headphone amp Channel 1}
8B Rear {to Headphone amp Channel 2}

As a diagnostic, I would disconnect 7B Rear and move it to 7A Front.
Disconnect 8B Rear and move it to 8A Front.
Re-test for proper operation of headphone amp stereo image.

Maybe I know what was wrong!
I don't if you read the manual of the my patchbay, anyway, I can't set the mode of the channel,s such as Mode1 pass thru, ecc because the patchbay uses the mode in according to the cables inserted.
Now, I don't know if this is the problem, but perhaps this could help you to understand.

I'm going to try your last suggestion!

You're right that the mode is set by which cables are plugged into which ports.

I was just trying to get you to use the "divide and conquer" technique of troubleshooting to narrow down where in the signal path the error occurred.

The biggest issue with this setup is that it has too many connections, and subsequently too many single points of failure.

I'll be interested in hearing what the problem was.
