Im pretty sure i put the shields of the 25way D's all together and straight through to the shields of the XLR outs/Insert points so the audio shields are all common but isolated from the chassis.
Ive got a pretyy bad memory so il have to check for sure when i take some pictures.
Im pretty sure i kept all the audio isolated from the chassis.
I did use Helterbelters resistor network idea, just 9K1 (1% tolerance) resistors i couldnt get hold of 10K's at the time and it wont make a difference.
The unit is at my work place right now and i wont be back there until sunday so il get some pictures then.
Yes,it´s needed (arround 40 dB loss,impedance will be arround 200 Oms).helterbelter said:Regarding the shunt resistor in NYD's summing design : Maybe it's needed when you use a micpre as gainmakeup amp, but I'm pretty certain it's not needed with the 552.
Let´s wait and see,hahahaha......helterbelter said:Regarding the lorlins : Yes, wiring them will be some work, but I'm sure the result will be great : )
With your earlier diy works (that I have seen) in mind, I'm sure this will be superdecent and tidy.
