3 You can now restore the offending project
from a backup, or take whatever steps are
necessary to restore the integrity of your
data.
Shutting down your SX-1 Proper shutdown
and regular backup of your SX-1 is extremely impor-
tant. Failure to shutdown your SX-1 correctly before
powering off can increase the possibility of corrupted
data in your saved files. Without regular backup, the
possibility that an unforeseen problem could wipe
out some, or all, of your data increases drastically.
When it comes to your hard work, don't take any
chances; always perform a proper shutdown and
backup of your projects after each session. See
“Shutdown Procedure” on page 24.
Being Grounded Never plug your SX-1 into an
ungrounded outlet. Nor should you plug a power reg-
ulator or a UPS into an ungrounded outlet. Neither
the power regulator nor a UPS can automatically turn
an ungrounded outlet into a grounded one.
Ungrounded power can introduce hums and buzzes
to your audio signal and can lead to serious equip-
ment damage (especially in the event of an electrical
storm). If your residence does not have grounded
outlets, contact a professional electrician about
installing an earthed ground.
Avoiding Ground Loops A ground loop occurs
when a piece of equipment sees more than one path
to ground. Ground loops cause hums, buzzes, and
sometimes even radio signals in your audio.
Needless to say, hearing the local weather station in
the background of your recordings is not desirable.
Ground loops can often be avoided by running all of
your equipment from a single wall outlet. Plug your
power regulator into one outlet and then plug all of
your equipment into that one power regulator. Most
power regulators have several outlets, and these out-
lets can be multiplied using standard power strips to
create plenty of free sockets. Setting your equipment
up in this fashion will direct every ground circuit to
one ground terminal and prevent a ground loop.
A ground loop can occur when two devices are
plugged into separate wall outlets on the same cir-
cuit, and the devices are also connected to each other.
This allows each device to reach ground by both
going through the other device and directly to the outlets. The result is a ground loop through which
noise and radio waves can enter your audio. To avoid
ground loops, make sure all of your equipment sees
just one path to ground by drawing all power from
one main power outlet.
