Happy New Year!
In adjacent real Neve modules they were on 50mm centres but there were two layers of sheet steel in between them.CheersIan
Hi Ian, yes I thought about that, on a Neve console they were really close but there was the sheet of it's own module and the sheet of steel of the neighbor .what do you mean by *50mm centres"?
Yes youre right, I guess the 2 steel sheets will provide some degree of shielding.But in the unit I have on my bench all the output transformers are really close to eachother with no shielding.What implications this might bring?
There will be some coupling between adjacent transformers but I expect it will be extremely small. Best thing to do is measure it. Send a signal through one channel and feed the output of an adjacent one into a mic pre. Slowly turn up the mic pre gain and see if you can hear anything.CheersIan
I will do that.would the possible problems be only coupling between transformers?Could also the magnetic field of one transformer interfere with the performance of the transformer next to it and vice versa?
In some desks where several output transformers were mounted next to each other i have seen a large L-bracket mounted under the transformer providing some sheilding between them.
what I wanted to ask also is if besides the crosstalk any of the following problems can occur also, or if crosstalk is the only concern.Hum or induced noise from the adjacent transformer?Lower signal because of magnetic interference?Altered frequency response?interference in the balanced output (signal + and - not 180 degrees of of phase)?
