Sorry for the long wait.
I will try to make another sample
It should be noted that the example recording made above is a highly increased volume section where I extract the sound with rather weak dynamics to hear reverb tail.
Regarding your questions:
The dynamics/eq section is off
I was testing reverb with a microphone on the microphone inputs. The same situation is seen on the microphone and instrument inputs.
I can hear this effect when just monitoring the channel through headphones with reverb and ucx ii in standalone mode without PC.
The recording was made like this: The cable goes from the guitar to the rme instrument input, the send fx fader is raised on the input channel (e.g. Analog 3), than choose adat 1/2 channel and raise analog 3 channel fader for direct mon., and also raised the fader for Fx return on adat 1/2 channel + enable loopback.
—The DAW is recording signal from adat1/2 to track.
I don`t know why, but this type of monitoring sounds a little bit different than direct Analog 3 channel monitoring , but I can assure you that I hear exactly the same jet sound and noise level raising when directly monitoring any input channel through the headphones with reverb turned on
The reverb jet noise doesn't respond to what I'm playing or what happening in my room. it's a strange sound that appears when the reverb tail modulates - phrase or word just had to be long enough to hear it completely.
