INSTALLATION CONSIDERATIONS

Placement

CAUTION! Placing the SI-1260’s weight on the rear or front panels will cause dam- age to the amplifier’s connectors or controls.

Place the SI-1260 on a flat, level surface like a table or shelf. The SI-1260 must be placed with its weight equally distributed on the unit's four feet. This amplifier, like any high-fidelity component, will last much longer if it is given adequate ventilation for proper cooling. When installing the SI-1260 in a cabinet, be sure that the cabi- net's rear is open to fresh air (see Figure 11). Additionally, place the SI-1260 so that there are at least 6 inches of free air space above the amplifier and 1 inch on each side. If the amplifier is located on a carpeted surface, place a board under the ampli- fier's feet. 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 12).

CAUTION! When using low impedance speaker loads (less than 4 ohms Normal Mode, less than 8 ohms Bridged Mode), refer to figure 12 for proper placement.

CAUTION! DO NOT block the ventilation holes on the top and bottom of the SI- 1260.

The SI-1260 is equipped with a massive toroidal power transformer. This transformer generates a powerful magnetic field that could induce a hum in a turntable (particu- larly a turntable equipped with a moving coil cartridge). DO NOT place a turntable directly above or directly adjacent to the SI-1260.

CAUTION! Before placing the SI-1260 on a shelf, verify that the weight bearing capacity of the shelf is 70 lbs or greater.
