- The SSL EQ Work Nice



- Now i need to clean the audio buzz when i use a dynamic mic ... / with a line souce and 48v mic no problem ....

- when i use the  PAD -20 on the JLM go Between when i check the audio curve on Smaart 7 i can See a HPF (100hz) more the PAD ?????!!!!!! stange no ?

- Question : How i can wire an Asymetric Input fot he CLX board ? i wire the pin 2 to the pin 1 and i use the pin 3 for the audio ?

How i can adapt 2 VU LED meters and Where on the PCB : the first for the Input/ Output and the 2nd for the audio compression ?

i can use any VU led METER for that ?

any idee ?

thx



 
looking good man! im thinking about starting a simliar project, with a nyd one bottle a helios eq and a comp (not sure which yet)

for the input to the clx, youde probably be better off with some kind of balancing board but you can try just wiring the xlr input unbalanced

Hy !

thanks for your wire config !! ;)

I have just see a new problem on my CLX board : my INPUT is Unbalanced : audio IN pin 3 Ground pin1 + pin 2 BUT My OUTPUT is UNBLANCED ???? why ? i have no Sym to the OUTPUT of the CLX Board ?
 
im not quite sure what your question is, the clx board does the balancing out via a opamp, are you saying you want to come out of the board unbalanced? heres a link to the board layout, look at the top right and left it gives you the pin out for in and out xlr and what each pad is

thanks for your answer mus1k_freak !

my question is : the CLX board use a balanced (eltronic) output ?
 
Yes the output uses a LM301 for balancing the output

NOW the Channel strip work perfectly !!!!

First :  i have change the toroid 25va to 50va !!!

and for the polarity of GR meter of the CLX i have change the TL071 by a TL081 !!!


Picture soon !

 
BRAVO!
This is a small beast!
You better do a faceplate quick for this beast because it deserves to look fancy!

How did you do the GR meter for compressor? Can you share the schematic for the LED GR section?
Did you have to modify CLX's meter driver?
