CH1-4 Stereo Line Input
RCA phono.
Connect stereo line level music
sources such as CD, MD, DAT,
drum machines, keyboards or
other instruments. Do not
connect turntables which require
RIAA equalisation. Alternatively,
you can connect to jack sources
using a cable with RCA to jack
adapters. Avoid using low grade
cables such as those often supplied
with domestic equipment as these
can quickly prove unreliable in use.
2
AC Mains Input
IEC cable with moulded mains plug
suitable for your local supply.
Important: Read the SAFETY
I N S T R U C T I O N S s h e e t
included with the Xone:4D and
printed on the rear panel.
Check that the correct mains lead
with moulded plug has been
supplied with your console. The
power supply accepts mains
voltages within the range 100-240V
without changing any fuses or
settings.
Ensure that the IEC mains plug is
pressed fully into the rear panel
socket before switching on.
Note: It is standard practice to
turn connected power amplifiers
down or off before switching the
console on or off. This prevents
any audible switch-on thumps.

CH1-3 Stereo Phono Input
RCA phono.
Plug in turntables with magnetic
cartridges requiring RIAA
equalisation. For non-RIAA
turntables plug into the LINE input
instead. Do not plug in line level
sources to the phono inputs as
these will overload the preamp and
cause severe high level distortion.
3
Chassis Earth Terminal
A screw terminal is provided for
connecting the earth straps from
turntables. This connection earths
the metal parts of the turntable to
reduce hum, buzz or similar
audible noise getting into the
system.
FX1-2 Line Return Input
RCA phono.
Connect stereo line level sources
such as the return signal from
external effects units. These inputs
are routed directly to the main mix
as the default setting, but this can
be changed internally to send them
to the Filters and crossfader (see
User Options)
