Installation
The ampli er is supplied with rubber feet which
make it possible to set the unit directly on a table or
shelf. Position the unit horizontally on a sturdy, at
surface. To ensure normal cooling of the unit, choose
a position that is well-ventilated, not exposed to
direct sunlight, and far from any heat source.
WARNING : To prevent the unit from
overheating, it is essential to leave a free
space of at least 5 cm (2") behind the
rear panel and in front of the side panels, and at least
15 cm (6") above the upper panel; in any case, never
situate the unit inside a completely closed structure.
Do not situate the unit in places that are subject to
high-intensity vibrations or particularly exposed to
dust or humidity.
NOTE: The UP 4061, UP 4121, and UP 4161
ampli ers are cooled by natural convection : the cool
air enters the unit through the air vents situated on
the lower part, and the heated air from the internal
heat dissipaters leaves the unit through the air vents
located on the upper cover. This system avoids the
need for periodic air lter cleaning which is typical of
fan-cooling systems, and also reduces dust intake
into the unit.
Rack installation
WARNING : To install the ampli er in a
rack, only use a rack enclosure that is
equipped with air vents and which fully
satis es the requirements of the EN 60439-1
standard.
To install the ampli er in a rack in the space of two
units (2U = 3.5" = 88 mm), you need to purchase the
AR 1052-N accessory (code no. 173.10.059) and
carefully follow the instructions provided with the
accessory. The ampli er must be attached securely to
the rack, especially when the rack will be frequently
moved or transported. When arranging the
equipment in the rack enclosure, place heavier
equipment in the lower part and lighter equipment in
the upper part.
To ensure adequate ventilation, leave a free space
of at least one rack unit (1U = 1.73" = 44 mm) above
and below the unit (see Fig. 17, pag. 47). When
multiple ampli ers are to be installed in the rack, it is
essential to use cooling fans in order to facilitate cool
air intake and hot air outtake. The table below shows
the maximum number of ampli ers that can be
installed in a rack which is not equipped with cooling
fans.

One solution could be to install a ventilation panel
with fans in the upper part of the rack which will
expel the hot air, and a ventilation panel in the lower
part (where necessary also equipped with fans) to
allow cool air intake (see Fig. 17, page 47).
