Gentlemen, this is a "try" to drow an amp for gainup the 8 ch balanced NYD passive box, using the neuman OA10.( I 'got some) I've used the design of a mic pre found in the tecnical paper of the Neumann AO10 as tipical applications, as fisrts stage and second one a buffer out with a small EQ.
first question is if this value are right or not, and if all this does make sense.
I have thought to use an OEP 1:6.4+6.4 as an input; if so, at the sencondary of the trasformer patched in series, I 'll find about +20db right ?
so I will need 24 db more by the input op amp to compensate the 40 db lost of the passive summing, right?
the fisrt OpAmp got to gain about 50 time. witch resistor I've to change R5 ?
do you think is possible to use one half of the secondary of the output trasformer to go to a recording machine, and the other half to drive an amplified control room monitor pair?
in this case I've to add a pot after the secondary or a buffer is needed ?
thank you
M.
