Carvin xp4 User Manual

The Carvin XP series is a line of quality digital effect processors

designed for professional use in studio and live sound reinforce-
ment applications.  The XP2 and the XP4 are identical except that
the XP4 has 4 processors instead of 2.  Thus, the XP4 is capable
of processing 4 independent mono channels, 2 stereo pairs or 2
independent mono channels and 1 stereo pair in a single rack
space.  The XP series processors deliver this performance
through the use of easy to configure effect engines that may be
placed in either stereo or mono mode.  This allows the XP2 and
XP4 to work with stereo audio sources while still maintaining the
flexibility to provide independent mono processing when it is
needed.

In independent mono engine processing, the engines may be

digitally linked in a serial fashion thus allowing each side of the
XP4 to function as a multi-effects processor.  

The footswitching capabilities of the XP processors are unparalleled in their flex-

ibility.  The unit can be easily operated in a live situation without requiring the
use of MIDI.  Our flexible footswitching setup allows you to bypass either effect
engine independently, both at once, or alternately (channel switching) using
either our own FS22 footswitch or other footswitches that have a 1/4" plug and
suitable switch circuits!

Both the XP4 and XP2 have a comprehensive MIDI implementation that allows

you to select effect programs and change any parameter or effect program that
has been selected on either side of the XP4 (this includes the effect wet/dry set-
ting which is included in the effect program setup for each effect engine).  MIDI
channels may be selected for each effect engine and/or optionally disabled with-
out having to disconnect cables.
