INSTALLATIO N CON SIDERATIONS
Place the SI-1230 on a flat, 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-1230, like any hi-fi component, will last much longer if it is given adequate
ventilation for proper cooling. When installing the SI-1230 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-1230 so that there is at least 5" of free air space above the chassis. If the ampli-
fier 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-1230.
The SI-1230 is equipped with a massive toroidal power transformer. This trans-
former 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-1230.
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.
M ake sure that there is a minimum
of 5” of free air space above the
amplifier and 3” on each side for
Allow a minimum of 2” of depth
behind unit to accommodate cables
and connectors .
