S/PDIF
The S/PDIF In and Out ports are unbalanced
two-conductor phono (RCA) connectors that
can run at up to 24-bit, 96 kHz resolution.
The Sony/Philips Digital Interface Format
(S/PDIF) is used in many professional and con-
sumer CD recorders and DAT recorders. To
avoid RF interference, use 75-ohm coaxial cable
for S/PDIF transfers and keep the cable length to
a maximum of 10 meters.
AC Power Input
The AC power input accepts a standard IEC
power cable (one is included with Eleven Rack).
The power supply in Eleven Rack is universal, so
wherever you go, all you need is a standard IEC
power cable with the correct plug for your re-
gion.
Line Inputs
The Line inputs accept one stereo or two mono
line-level analog signals. The Level switch lets
you choose b4 or –10 dBV, for compat-
ibility with professional and consumer gear.
MIDI I/O
The MIDI In and MIDI Out ports are standard
5-pin MIDI ports, each providing 16 channels of
MIDI input or output. These ports can interface
with a variety of MIDI devices
When Eleven Rack is used as a standalone pro-
cessor, the MIDI jacks are used to communicate
with MIDI foot controllers, sending and receiv-
ing program changes and continuous controller
data.
Exp Pedal/Ext Footswitch Input
The Exp Pedal/Ext Footswitch input supports an
expression pedal or a momentary footswitch
(single or dual). You can control sweepable pa-
rameters (like Wah, Volume and Multi FX) with
an expression pedal, or switchable settings (like
Rig switching, amp channel switching, and ef-
fects on/off) with a footswitch.
Eleven Rack can use either AES/EBU or
S/PDIF, but not both at once. For informa-
tion on switching between digital formats,
see “Digital Format” on page 58.
