I think you misunderstand something. 5534's have compensation caps across pinsage said:Now i do need a suggestion - I remember Jim Williams talking once of the importance of removing coupling cups if using more modern op-amps like the LT1357 or OPAs, so I wonder are the coupling these once in the picture? Shall I remove them?
only remove compensation caps #1 and #3, connecting to NE5534-pins 5/8 (both probably 22pF) for differing opamp.sage said:all 4 of those?
Considering the way it is connected and the fact that the audio voltage is partially injected, I think it is probably a dual FET.gyraf said:Strange way of doing gain reduction..
What component is U2 on the limiter card?
Jakob E.
Looking at the schemo of both the EQ and the comp, the input stage is unity gain. When the units are in bypass, the output comes directly from the input stage so you should not experience any loss, but make sure the negative input leg is connected.sage said:all those EFT units loose 6 dBs even in Bypass -
I know they are unbalanced so could this be the reason?
That is a sign that there's something wrong in your installation, unless you have very long cable runs, which I doubt.sage said:At the moment I have installed the Optional Output Trafo on 2 units, one has the Cinemag CMOB-2L, the other the CMOB-2H -
Sonically the one without trafo sounds very close to the CMOB-2L but it has incredible noise and interference, so the trafos really take care of all that junk making the signal really nice and clean.
No. Don't change the output wiring.sage said:HI
i wanna make sure i understand correctly... if i put signal in - to pin 11 than do i also put signal out - to pin 11 ?
The output xfmr should be connected between pin 10 and common (pin9 - 3).Ground from XLR right now goes to chassis thru the xlrs and then to the main ground from power - as at right now ground from Common is not connect - only wire connected is RED to Trafo -
My only question is right now My OUTput trafo has a wire connected to 11, I assume that is the common to trafo but what do i do with it?
