Where is the best placement in order to use an external preamp when using a 003 Rack combined with the Control 24. Should I take the Protools out cable before going into the 003 rack using a patchbay for preamp selection and then introduce the preamp or should I simply run my booth mic directly into the external preamp via the patchbay and then xlr cable out from each external preamp into a chosen xlr mic input path on the back of the Control 24? Running 8.0 LE - 003 Rack, Digimax FS with three external possible choices in Preamps. I would also like to know where the Antares AVP-1 should be introduced in the path as well - Thank you
