Niles Audio SYSTEMS INTEGRATION AMPLIFIER SI-275 - Manual (Page 6)

INSTALLATION CONSIDERATIONS
Placement
Place the SI-275 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 will result in damage to the
amplifier's connectors and controls.
The SI-275, like any hi-fi component, will last much longer if it is given adequate
ventilation for proper cooling. When installing the SI-275 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-275 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-275.
The SI-275 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-275.

If the cabinet rear is not open to
fresh air, install two small “boxer
fans” 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 2” of
depth behind unit to accom-
modate cables and connectors.
