When stacking 2 compressors you want to make sure each successive compressor has a lower ratio than the one before it.
Add an 1176 to your vocal track.
Set the ratio to 12:1 and the attack and release to the fastest setting (7).
Adjust the input gain until you are getting 3-5dB of reduction on the loud peaks of the vocal only. Make sure there is no gain reduction happening on the rest of the vocal.
Adjust the output gain to where the volume is the same engaged as it is bypassed. This is called gain staging.
Add an LA-2A after the 1176 and make sure the Limit/Compress switch is on compress.
Adjust your peak reduction until you are getting about 5-7dB of compression.
Time for some more gain staging. Adjust the gain on the LA-2A to where the volume is the same engaged as it is bypassed.
You have a much more controlled vocal without any compressor artifacts such as pumping or breathing.
