line level compression
- View SourceHi,
We love LecNet 2 DMs. We have notices some instances of distorted
audio when operating compressors or limiters with line level inputs.
Inputs meter normally, and the sound cleans up when raising the
threshold to a point where there is no gain reduction, or the ration
is changed to 1:1. Anyone else notice this or have a tip?
- View SourceHi Mark,
I saw your posting last week, but was not able to respond until
now. We have also noticed this distortion, and have contacted the
factory about it. To date, they have not been able to duplicate it
(to my knowledge). At times, I have not been able to use this
feature because of it. Specific details sent to the factory may
help, if you have them...

Check the attack time on the compressors - I ran into the same thing
at my church where we have the beta test unit - the units used to
ship with an attack time of around 1ms on compression as "standard"
- the moment you activated the compressor by picking a ratio, this
was the default.
Change that to a more reasonable 20-30ms and it smooths out. We now
ship them set to 20ms as the default.
Also double check input gain - make sure you aren't overloading the
input. (I know Mark wouldn't do such a thing but I still have to say
Check those attack times (also make sure the release time is LONGER
than the attack - I typically use 200ms in the church. I use a 3:1
My church is about 2 mile sup the road and very convenient for
testing in a live environement with a bunch of amateurs running
things - nothing a field installation where you can see what we
missed in the lab. The church jokes about being a beta site -

- View SourceHi Gordon,
Thanks for the tip. I usually set the attack a bit quicker than 20mS,
but we will give that a try. Is there any thought as to why that
particular symptom shows up with line level and not mic level inputs?
