Introduction to PRE
Welcome to the Digidesign
®
PRE™ multi-pur-
pose microphone preamplifier for Pro Tools
®
systems.
PRE is designed especially for use with Pro Tools
systems, but it can also be used as a stand-alone
microphone preamplifier. When used with
Pro Tools, most PRE features can be controlled
from within the Pro Tools application.
With or without remote control, PRE can be
configured manually using its front panel
switches and displays.
PRE can also be remotely-controlled by other
MIDI devices through standard MIDI controller
data. See Appendix C, “MIDI Controller Num-
bers.”
