OPERATING CONTROLS
Subwoofer Le vel 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 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”.
Phase Switch
This toggle switch allows matching of the phase of the subwoofer with that of your
main/satellite speakers. Switchable to 0° or 180°,it compensates for the mid-bass
acoustic effects of different speaker locations and listening room acoustic effects. See
“Set-up and Calibration”.
LF EQ Switch
In either High Level or Low Level connection,this switch adjusts the extreme low
frequency characteristics of your subwoofer. It switches from –3dB through 0 to +3dB to
precisely match the subwoofer with the acoustics of your listening room. Set switch to 0°.
If bass is too “boomy”and lacks deep detailed bass,switch to –3dB. If bass performance
lacks sufficient impact, switch to +3dB.
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.
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.
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.
