OPERATING CONTROLS

Subwoofer Level Control

This rotary control adjusts the output level of your Mirage subwoofer and should be used to balance the level of the subwoofer with that on your main/satellite speakers. See “Set-up Calibration”.

LP Filter (Low-pass) Control

This rotary control adjusts the high frequency roll-off of the subwoofer. Continuously variable from 50Hz to 100Hz, it is used to precisely match the subwoofer bass reproduction with that of your main/satellite speakers. See “Set-up Calibration”.

ROOM ACOUSTICS AND

SUBWOOFER PLACEMENT

Mirage subwoofers can be placed virtually anywhere in your listening room without significantly affecting the stereo image of your main speakers. However, interactions between any subwoofer and room acoustic properties will have some impact on the overall bass performance. Reading this section will help you to find a placement for the subwoofer in your room which will yield the best bass performance.

CAUTION: MIRAGE SUBWOOFERS HAVE A BUILT-IN AMPLIFIER AND MUST HAVE ADEQUATE VENTILATION FOR COOLING PURPOSES. DO NOT PLACE THE SUBWOOFER NEAR HEAT SOURCES, OR ANYTHING WHICH MIGHT OBSTRUCT VENTILATION.

Although a clear path between the subwoofer and listening position is not required, it is important to leave approximately 4 inches of clearance between the subwoofer and walls or room furnishings. Generally, shorter runs of hook-up cables are preferable (and easier to hide), therefore locating your subwoofer relatively close to your audio equipment is often desirable.

The interaction between room acoustics and any subwoofer is closely related to the subwoofer’s proximity to the walls. Typically, subwoofer placement directly in or close to a corner will produce the most bass output, placement along one wall but away from a corner will produce less bass output, and placement of the subwoofer further into the room will produce the least amount of bass output. It should also be realized that the corner location, although producing the most bass output often yields ill-defined or “boomy” bass. The latter two locations will deliver progressively more accurate bass performance.
