I realize that a small very number of bassists use a 500 series rack in their live rig. I've used a number of rack mounted preamps into a racked power amp for 20 plus years. In an effort to refine my live sound and have a nice preamp for studio sessions, I'm looking at 500 series gear. When I use my Alembic F1X, for instance, I have the choice of a sending the house a pre or post EQ signal from the XLR on the front and a 1/4" feeds my power amp. If I set the preamp to PRE, I can adjust my volume and EQ to my rig without affecting the house. I'm curious how others have figured out how to send the house signal from a 500 series preamp while be able to adjust the volume to the power amp (without affecting the house level). The idea is to feed the house and my rig the same preamped signal. My current power amp has level controls, but the ones I'm looking at to replace it (Lab Gruppen, etc.) don't have front panel controls for volume. Maybe there's a menu driven way to do it, but I'd like an elegant hardware solution, if possible. I was thinking of not having any EQ in the path, if possible, as I hardly ever touch my EQ. I have a few basses with the pickups wired directly to the jack and enjoy the purity of sound. However, if I need another unit to control the level to my power amp, I'd consider an EQ with an output level (if they exist). The Radial Powerstrip 500 series rack I'm looking at has both XLR and TRS in/out, so I'm guessing I could accomplish the split to house (XLR) and amp (TRS) that way. So, long post to ask: if you use 500 series gear in a live rig, how do you configure it?
