Installation Considerations

Placement

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.

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

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

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

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.
