Mounting
All
of the
units
in
the
Alesis
MICRO
SERIES
are
rack-mountable
in
the Micro Rack
Adapter,
where
any three
units
fit
perfectly.
Assembly
is
quick
and
simple with a
single screw
securing
each
device in
place.
The
unique
design of
the
MICRO
SERIES case
allows
the devices
to
lock
together to form
a solid
rack
package,
or to
stand alone
as single units.
Power
The MIGRO
SERIES
is
powered
by a
remote
supply
providing
9
volts AC
through a 3.5mm
plug.
This
external
power
supply
approach
keeps
stray
magnetic fields from interfering with low
level
signals,
allows
easy conversion
to alternate
power
sources
(220V),
and
further reduces
the unit's
physical
size and
valuable
panel
space.
Although
many MICRO
SERIES
devices could be
powered
by a single supply, this
is not
advisable as
ground
loops
could
possibly
occur between
units,
leading
to excessive
hum
and
noise
in the system,
