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 I/O
The FX Loop I/O is a pair of 1/4-inch TRS inputs
and outputs, which can be used to insert a mono
or stereo external effects processor into the gui-
tar signal. A switch is provided to adjust the sig-
nal level to be suitable for either a line-level ef-
fects processor (Rack FX) or a guitar-level effects
processors (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.
Output To Amp 2 (R)
The Output To Amp 2 (R) is one of two outputs
specifically designed for connecting to the input
of a guitar amplifier or effect. It can be used in-
dependently of Output 1 (located on the front
panel), or along with it for stereo amplifier con-
figurations.
Digital Inputs and Outputs
AES/EBU
The AES/EBU In and Out ports are balanced
three-conductor XLR connectors that can run at
up to 24-bit, 96 kHz resolution.
The AES/EBU format is used in many profes-
sional digital converters, recorders, and signal
processors.
