Hi guys...
I have to record a full strings orchestra, with 72 channels... my idea is to modify the behringer ada8000 which has bad mic preamp (in my opinion) and put into the box 8 green pre mic by peter cornell.... i did the board but i miss the component layout and the gerber file... someone has got it yet? Because the site 1176neve is closed...
Other question... Im putting 2 lm4562... the lm4562 is a +17 - 17 v instead the behringer has +18 and - 18 and im changing the resistors on the power supply to 100 ohm ... shall it work??
Last question... Im putting a log pot instead the rotary switch... Im thinking 150K should be ok... what do u think???
My email is maxmoioli@infinito.it. if someone could kindly send me the 2 files 8gerber and component layout)....
thank u
Regards
