neve 33609

[garnon]

hello everybody
this is my first login
i am a french sound engineer

i have an hold 33609 neve's compressor and i want to modify the threshold
it works actually between -20 to +10 db
i need at least 10 dbs more so -10 to +20db
does anybony know how to do the modification ?
thank's for your answer
i asked the same question to geoff tanner few months ago
he gave me an answer an i tried to do what he told me but i didn't succeed
and i burned two transistors,maybee i did a big mistake, i'm not so good in electronic
so i need some help
i have the manual whith schematics, i can scan and send them

Dude! You might want to go see a tech!

Hi

I dread to think what you modified to burn out transistors... they are not even close to the mod!

All the threshold is.. is a stepped attenuator driving a fixed gain amplifier. I suggested that you stick a resistor in series with the attenuator to allow a higher threshold... this is external to the motherboard... and with the caveat that, if you don't know what you are doing... don't do it.

That's the problem with trying to help folk, I suppose.

If I were you, I'd put up with the figures it currently achieves.

hi geoff
thanks again for your answer
don't worry about my compressor, it still works as well as before
i did a mistake but i fixed it mysef changing transistors and it's ok
i have followed your suggest sticking a 4.7 k resistor in series whith the step attenuator and i agree with you, it's external to the motherboead
but i met this problem
i will try again
