Hello everyone,
I have one question. How can I do a stepped output pad (attenuator) for the Neve 1290 preamp?
I know it can be done by putting a 5K (or 10K) linear conductive plastic potentiometer behind the second section i.e. BA283NV and before the output section i.e. BA283AM.
I have some 4 position (3 deck) switches that I want to use for that. I would like to have these values of attenuation:
0 switchs position (fullclockwise) …………….….. 0db
1st switchs position……………………………….........-6dB
2nd switchs position ………………………………......-12db
3rd switchs position (counterclocwise)……....-20db
Would be there funktional a basic 600 ohm L pad for attenuating unbalanced signal?
Is good idea to use rotary switch instead of a conductive plastic pot?
Any help would be much apriciated!
