hi Sascha,

Very interesting your grounding system!
How did you build the hf filters?

Why do you want to use a DI for connecting your monitors to the
console?
Are you encountering problems doing it without?

I don't use any DI and it works fine.
I have some hum/buzz starting at the 3 o'clock position of my CRM pot,
but that's already very loud and I don't monitor at such a level.

Some words for the symmetrical mod of the line in's.
I do own some Dayner split modules which have been modified in that
way by using a transformer.
As I bought them used, I don't know if the mod has been done by Dayner
or by someone else.
If you're interested in details, please let me know.

greetings,

Pierre

Hello Pierre

Thank you for your help. I have big trouble! In the past, my monitors
are connected to the master outputs. in this way, everything works
fine (zero hum or ground loops!). but now, when i plug it into the crm
out, groundloops whithout a end!! and when i plug in the headphone amp
in the aux 1+2 the desaster is perfect. it seems i have to redone the
complete wiring. can you explain me exactly, how i connect the in and
out to and from the motu (tape send to the motu in, tape return to the
motu out)? I don"t understand completely your wiring example in the
previous post:

My first connection "trial" for the outputs on the MOTU was the
following:
MOTU XLR pin 1 (ground) - cable shield, not connected to the stereo
jack on Dayner (to avoid ground loops)
MOTU XLR pin 2 (hot) - ring stereo jack on Dayner (+4 dBu)
MOTU XLR pin 3 (cold) - sleeve stereo jack on Dayner (audio ground
on
Dayner)
What happened was that I had a low level signal from the MOTU on the
monitors with even all mute switches activated!
I can only explain this that the signal from pin 3 on the MOTU was in
some kind modulating the audio ground of the console.


So I did the following:
MOTU XLR pin 1 (ground) - cable shield, again not connected to the
stereo jack on Dayner + sleeve stereo jack on Dayner (audio ground on
Dayner)
MOTU XLR pin 2 (hot) - ring stereo jack on Dayner
MOTU XLR pin 3 (cold) - not connected
and everything worked as expected.
What do you mean with: MOTU XLR pin 1 (ground) - cable shield, again
not connected to the
stereo jack on Dayner + sleeve stereo jack on Dayner (audio ground on
Dayner)


Is this solution the same for the tape send and tape return?
please help!

much greetings
