If the cabinet rear is not open to fresh
air or if your using low impedance
loads, install two “boxer fans” to pro-
vide continuous air flow into and out
of the cabinet.
Make sure that there is a minimum
of 6” of free air space above the
amplifier and 1” on each side for
proper ventilation.
Allow a minimum of 2” of depth
behind the unit to accommodate
cables and connectors .

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.
