Pioneer SI-245 - Manual (Page 6)

INSTALLATION CONSIDERATIONS
Placement
Place the SI-245 on a flat level surface like a table or shelf. It should be placed
upright so that its weight rests on the four attached feet. Placing the weight of the
amplifier on the rear or front panel for even an instant may result in damage to
the amplifier's connectors and controls.
The SI-245, like any hi-fi component, will last much longer if it is given adequate
ventilation for proper cooling. When installing the SI-245 in a cabinet, be sure
that the rear of the cabinet is open to fresh air to provide proper cooling (see
Figure 1). If the cabinet’s design will not accommodate an open rear, install two
small “boxer fans” to provide continuous air flow into and out of the cabinet (see
Figure 2). Place the SI-245 so that there is at least 5" of free air space above the
chassis. If the amplifier is located on a carpeted surface, place a board under the
amplifier's feet. Do not block the ventilation holes on the top and bottom of the
SI-245.
The SI-245 is equipped with an internal transformer, which generates a powerful
magnetic field which could induce hum in a turntable (particularly a turntable
equipped with a moving coil cartridge). Do not place a turntable directly above
or directly adjacent to the SI-245.

If the cabinet rear is not open to
fresh air, install two small “boxer
fans” (55cfm fan) to provide
continuous air flow into and
out of the cabinet.
Make sure that there is a minimum
of 5” of free air space above the
amplifier for proper ventilation.
Allow a minimum of 5” of
depth behind unit to accom-
modate cables and connectors.

AC Power Plug
STEP
Plug the female IEC socket of the sup-
plied AC cord into the IEC receptacle
on the rear of the amplifier.
Plug the 2 prong plug into a correctly
grounded 230V 50 Hz wall outlet.
CAUTION! Typically the
preamp/receiver’s switched outlet is
not rated for a power amplifier.
DESCRIPTION
Just like a computer or printer, the SI-245
has an AC cord which unplugs either at the
amp or at the wall for your convenience.
If you use a grounded power strip, surge
suppressor or extension cord, verify that
proper ground is maintained.
The SI-245 draws a maximum of approxi-
mately 200 watts from an AC wall outlet.
Use the auto turn on circuit instead.
