Front panel mounting
The APU-RSi(C) is designed to fit into a
standard 19 inch equipment rack via 4
mounting holes in the front panel and
has a height of 1U (45mm/1

The fixing hole dimensions are shown in
the diagram below.

Alternatively, the APU-RSi(C) can be
placed on a shelf. Other equipment (up
to 10kg/22lbs) may be placed on top if
necessary. Take care not to scratch the
top of the case and that any weight is
not directly over the centre of the APU-
RS16i.
NOTE: The APU-RSi(C) does NOT require
ventilation and therefore its
installation position is not critical.
The APU-RSi(C) should ALWAYS be
installed in a dry environment that does
not exceed 35 degree Centigrade (95
degree Fahrenheit).
The product’s steel case provides all
necessary shielding from magnetic fields
generated by the APU-RSi(C) itself (these
are very small) or from other equipment
placed nearby.
Operation
Cautions in use
It is not recommended that you
intentionally cause the APU-RSi(C) to
automatically protect the loudspeakers
by deliberately over-driving them. If you
find that the APU-RSi(C) automatically
reduces the audio volume from the
loudspeakers frequently it may suggest
that the amplifier being used is too
powerful or that the layer of plaster over
the speakers is too thick.
WARNING: DO NOT switch on the
amplifier unless both APU-RSi(C)
and loudspeakers are connected to it.
Damage may occur to the amplifier if
it is operated without a loudspeaker
connected to the output of the APU-
RSi(C).
Using the APU-RSi(C)
There are no controls on the APU-RSi(C)
and no need to change any settings
unless the model of connected speaker is
changed.
