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.

Make sure that there is a minimum of 5” of free air space above the amplifier for proper ventilation.

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.

Allow a minimum of 2” of depth behind unit to accom- modate cables and connectors.
