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 7” 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-275.

CAUTION! When using low impedance speaker loads (less than 8 ohms Normal Mode) refer to Figure 2 for proper placement.
