Another SSL - How boring

[gyraf]

..the load impedance in that point is 10k (20k//20k)..

Hey,

From other ssl sidechain posts it was mentioned to take the 'To S/C' signals (from 22uF caps after input opamps - before 15K resistors) not from the sidechain opamp...

If you look in the SSL meta thread theres a ckt posted by Steffen (as i remem) that has all the cap values etc for the freqs...

 

[Ptownkid]

WOW, that looks fantastic!!!

 

[gyraf]

daArry,

yes, you're right. But it will probably also work here..

highpass filter... now THAT's an idea. I'm sure glad I didn't order my front panel last week like I planned.. :grin: :thumb:

I looked for that post from Steffen, and I found this thread.

There was schematic posted in that thread that is no longer there. Does anyone still have it?
Thanks,

Hey,

Jakob - thanks for the heads up..

Mike, here's the ckt:

To make the sidechain balanced I just added a DRV/INA134 combo on the sc send and rcv signals...

Best,

 

[gyraf]

..in real-life, you don't really need balanced sidechain eq insert..

please save to disk, I don't know how long I will have it up:

This design involves a dual opamp.

In the modification of Matthias, what kind of caps can I use, electrolytics don't go as low as I need them to be? ceramics?

 

[martthie_08]

jeez, you guys are really quick sorry for redundancy...

 

[gyraf]

ceramics?

..polyester..

 

[daArry]

Thanks again Jakob! I just had those bal chips laying around and just breadboarded the s/c ckt so thought I mightaswell wack em in...havnt even made use of the ext s/c as the freqs already there are working great as-is... :thumb:

sorry for that... I´m moving to another webspace at the moment, so the links wont work anymore...

I´ve backups of the old sites and stuff so it will be online again soon...

Thanks guys.

here's one for daArry: :guinness:
and one for martthie_08: :guinness:
and since you drew it, one for Steffen: :guinness:
and hell while I'm at it, one for Jakob: :guinness:

Unfortunately, I'm at work and I won't be able to join you. Well.. maybe just one. :guinness:

:grin:

So would Steffen's circuit go in betwwen the 22uF caps and the sidechain VCA? Would the two 47K resistors then need to be taken out?
thanks,
mike

EDIT: oops, I got my answer in the SSL sidechain thread..
