INSTALLATION CONSIDERATIONS
PLACEMENT
Place the SI-1650 on a at, level surface like a table or shelf. It should be placed
upright so that its weight rests on the unit’s four 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-1650, like any hi- component, will last much longer if it is given
adequate ventilation for proper cooling. When installing the SI-1650 in a cabinet,
be sure that the rear of the cabinet is open to fresh air to provide proper cooling
(see Figure 19). If the cabinet’s design will not accommodate an open rear,
install two small “boxer fans” to provide continuous air ow into and out of the
cabinet (see Figure 20). Place the SI-1650 so that there is at least 5” of free air
space above the chassis and 3” of space on each side. If the amplier is located
on a carpeted surface, place a board under the amplier’s feet. Do not block the
ventilation holes on the top and bottom of the SI-1650.
The SI-1650 is equipped with a power transformer. This transformer generates
a powerful magnetic eld 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-1650.
