CP554 Diode bridge compressor / Re: CP554 setup-guide point 13

Side chain was on int.

I tried both compressors without board 2 on a drum track and to me they didn't sound like they were applying any compression. Maybe I'm tired but if there was a difference it was barely audible even on extreme settings.

How subtle is the unit? How delicately do I need to listen to hear a 12/1 ratio across any given threshold? There was little to no change. I've used plugin versions and they have great range so I'd suspect this does too and I've made an error. The same error on both units is surprising. They sound the same.

I tried the side chain set up again and was still having issues with the last step which I feel may be related to the above.

I've lost track a little as this level of trouble shooting is giving me serious brain fog!!

Hi @JPK

I am also struggling with step 13 but with different issue.

After setting the unit threshold to -6 and the tone from DAW to 6.15VAC, I switch on the bypass and nothing changes on the DMM and I get no change when I adjust TR3.  I kept going curious about what was going on there. -18db behaved the same. When I  try the last step at +9Db thresh and switch by pass on there is also no change to the 6.15VAC tone doesn't change to 2.6VAC.

The rest of of the setup up to this point has been really good.

I have two CP554's and have tried each side chain card in each unit and got the same results with all options.

Be grateful for any guidance.
