LA502 Optical Compressor / Re: Not working as expected during setup
« on: December 02, 2021, 05:54:14 PM »
Hi JPK
I did as instructed but it turned out that this wasn't the issue. The real issue was with my audio interface which the output I was measuring on was connected to. Once disconnected, things completely changed.
The unit is now calibrated and I have proceeded to step 7 - the sound check.
Generally, the unit seems to be working properly and sounds gooood, but I've noticed a few things:
Thank you for your assistance. Upon finishing this troubleshooting, I am ready to move on to the next DIY project.

Generally, the unit seems to be working properly and sounds gooood, but I've noticed a few things:
- When adding a lot of gain reduction, the transients from "pop-sounds" actually becomes a lot louder than in the original waveform even though the LA502 is used as a limiter - see image below. Maybe I was expecting the waveform to look more compressed in the limiter setup, but maybe I was wrong?
- When setting the unit up with my audio interface - Apogee Duet 2 - I very easily get sort of a "ringing sinus tone that becomes very loud when turning up the gain. The sinus tone keeps ringing in the unit even after DAW output is turned off. Is this a issue with the unit or something in the way my DAW and interface is setup?
Thank you for your assistance. Upon finishing this troubleshooting, I am ready to move on to the next DIY project.
