Niles SI-250 オーナーマニュアル

NILES AUDIO CORPORATION – 1-800-BUY-HIFI – 1-760-710-0992

2 CHANNEL, BRIDGABLE POWER AMPLIFIERS

Place the Niles System Integration Amplifier

®

 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 Niles System Integration Amplifier

®

, like any hi-fi component, will last much 

longer if it is given adequate ventilation for proper cooling. When installing 
the Niles System Integration Amplifier

®

 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 Niles System Integration Amplifier

®

 so that there is at least 7” 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 Niles System Integration Amplifier

®

.

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

Allow a minimum of 2” of depth behind unit 
to accommodate cables and connectors.

If the cabinet rear is not open to fresh air or if you’re 
using low impedance loads, install two “boxer fans” 
to provide continuous air flow into and out of the 
cabinet.

Boxer Fan (55 CFM) 
directly centered 2” 
behind the Amplifier.

Boxer Fan (55 CFM) 
directly centered 7” 
on top of the Amplifer.

Make sure that there is a minimum of 7” of free air 
space above the amplifier for proper ventilation.
