Here we go:
Compression settings for channel A. There is a MASSSIVE input gain, because I was a bit scared to bring the levels up while recording. The threshold is set so that it enables the compression only on really loud sounds - so it pretty much works like a limitter (ratio of 1:30). Very fast attack - not to let any loud sounds through.
Compression channel B + meters. Settings are the exact mirror of channel A (somehow I couldn't get the Stereo button to work). Gain makeup a little tweaked to keep the balance between left and right even.
EQ: Gain, Low-cut, High-cut, Low freq band and Low-medium freq band. The shelf/band switch was at 'shelf' position (LF).
EQ: High medium freq band, High freq band and master gain. Note that only Channel A (bottom one, apparently) controls the EQ as it is the master when they are linked using Stereo button.
Screenshot of Logic session while bouncing down from valves. On the right: Logic EQs. top one cuts down bottom of the signal that went to valves, to reduce humming noise I wrote about earlier. It was much easier to filter it out using Logic EQ than valves. The bottom EQ shows the reduction I done to the bounced down signal to eliminate hiss made by valve EQ.
Screenshot comparing original and bounced down tracks - note rather dramatic inrease of levels!
