INSTALLATION CONSIDERATIONS
PLACEMENT
Place the SI-1650 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-1650, like any hi-fi 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 flow 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 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-1650.
The SI-1650 is equipped with a power transformer. This transformer 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-1650.
