Eleven Rack Back Panel
Figure 2 identifies each port on the back panel of the Eleven Rack.
The Eleven Rack back panel provides the
following:
FX Loop Sends and Returns
The FX Loop Sends and Returns are a pair of 1/4-
inch TRS inputs and outputs, which can be used
to insert a mono or stereo external effects pro-
cessor into the guitar signal.
The Level switch lets you adjust the signal level
to be suitable for either a line-level effects pro-
cessor (Rack FX) or a guitar-level effects proces-
sors (Stompbox FX).
Main Outputs
The Main output section includes a stereo, XLR,
line-level analog output pair. Connect these to
studio monitors, a power amp, mixer, or PA sys-
tem.
The Gnd Lift switch is useful for suppressing
hum in some situations, but should usually be
left switched off unless it is really needed.

When sending and receiving mono signals,
use the Left/Mono input and output. You
can set the FX Loop to mono in this case, by
visiting User Options > FX Loop. For more
information, see “FX Loop” on page 92.
When using the Main outputs to feed a live
sound console, alert the sound engineer that
the signal you’re sending is line-level, rather
than mic-level.
Use caution when connecting the Main Out-
puts to devices (such as mixers), which pro-
vide 48V phantom power over the connec-
tion. We recommend that you make sure
48V phantom power is disabled on these
devices before connecting your Eleven Rack.
