So I have created some nice virual rigs and have them sounding really nice at home. At home I am going XLR direct mono into a small destop mixer, using one strip with it set flat then into active studio monitors. It sounds really good and I’m really happy. I use a mono setup input 1 and output 1 in stomp mode. So it is a simple rig.
I recently went out to audition for a group and used my quad cortex as the host had a similar mixer out into bigger PA speakers.
It was a nightmare. I had a lot of hiss and possible grounding issues. Any of the ODs when at home have a slight bump in DB but in the audition rig the bump was expodentially louder to the point of not beign usable. I had to ride the volume knob of the guitar to temper the noise and jump in volumes. It did effect how the audition went, not a big deal as I wasn’t really interested to play with those guys anyways but I digress. I didn’t expect to be fighting with my rig. I tried the ground lift on the input but it just made it noisier.
So after I replugged everything in at home it was back to what I expect and sounding great again.
So I’m not sure what was wrong at the audition. Others keyboard, acoustic guitar, 3 voices did not have the issue with noise I was having. I wasn’t getting clipping on the cortex itself and the channel strip didn’t seem to be clipping either. For the noise and hiss it was wierd. I know that I could gone into the input or output of the cortex and played around with all the ground lift switches and switched the switches but I just didn’t have the time to be messing around.
So I see in the output section I/O Settings Output 1/2 …
Output level (which is self explanatory)
Ground lift (again self explanatory)
Out Level (which you don’t want to go into the clipping level at your loudest)
Limiter ( which I don’t know if you can access like a compressor or similar)
Mute (self explanatory)
So my issue is when I take my Cortex out again if I get into these issues. How would I logically deal and troubleshoot if presented with these same noise, hiss and big jumps in volume from the ODs.
What did I do incorrect so it doesn’t happen again?
