Recommended connection for
Dolby Digital Systems: Xover Bypass
This method bypasses all subwoofer controls, other than phase, in favor of the
bass management controls integrated into your receiver or processor.
The rear panel is equipped with a low level input marked Xover Bypass.This
method uses an RCA cable to connect the "Subwoofer Output" jack from
your receiver or processor to the Xover Input on the rear panel of the
subwoofer. See diagrams 2, 3.
Recommended connection for Dolby Pro Logic
systems: Input
The rear panel is equipped with a low level terminal marked Input. Connect a
single RCA to RCA interconnect cable to what is commonly referred to as
the "Subwoofer Output" jack from your receiver or processor to the Input on
the rear panel of the subwoofer. This connection allows full use of all
subwoofer controls. See diagrams 2, 3.
Recommended connection for Stereo applications:
High Level Inputs and High Level Outputs
Located on the rear of your MIRAGE subwoofer are 4 sets of binding posts.
The pair marked Inputs should be connected to the left and right speaker
terminals of your amplifier or receiver. Each pair is color-coded black/red.
These terminals will accept up to 12-gauge quality speaker wire. Remember:
Always connect red-to-red and black-to-black when making connections
between amplifier/receiver to subwoofer. If you inadvertently reverse one
of the connections (i.e., red to black), you will notice a lack of bass from
your subwoofer.
The second pair of high-level terminals are marked High Level Outputs and
can be used to transfer a signal to your speakers. Using speaker wire, connect
the left and right outputs to the rightful speaker inputs. Each pair is color-
coded black/red.These terminals will accept up to 12-gauge quality speaker
wire. Remember: Always connect red-to-red and black-to-black when making
connections between amplifier/receiver to subwoofer. If you inadvertently
reverse one of the connections (i.e., red to black), you will notice a lack of
bass from your subwoofer. See diagram 3.
Set Up Calibration for High Level and Subwoofer
Input Connections
*As previously mentioned, the Xover Bypass input renders the subwoofer's
controls, other than phase, inoperative in favor of the bass management controls
integrated into you receiver or processor. Simply turn the subwoofer on and follow
the guidelines of your processor's manual.
For best results when setting up your system, assume your normal
listening position and, if possible, have another person perform the
following adjustments.
1. Complete your connection method and turn the subwoofer on.
2. Set the subwoofer Level control to its lowest position, completely
counter clockwise. Set the subwoofer Frequency control to its lowest
position, completely counter clockwise. Play a familiar piece of music or
video soundtrack that has substantial bass content.
3. Gradually turn the subwoofer Level control clockwise until you achieve a
neutral volume balance between the subwoofer's deep bass output and
your main speakers. See diagram 4.
4. Slowly turn the subwoofer Frequency control clockwise to reach the
best midbass with your main speakers. This will be the point at which
bass retains solid impact and fullness. If the bass is too boomy or ill
defined, you have gone too far and should turn the control
counterclockwise to the best balance point. If the sound is too thin, then
turn the control clockwise to the best balance point.
See diagram 4.
5. While in your listening position, have someone slowly adjust the Phase
between -180 and 180 degrees until you've decided what provides the
fullest, most accurate bass.
6. You may have to readjust the Level Control due to the effect of the
Phase Control.
The Subwoofer Level Control is designed to control the balance between
your subwoofer and main speakers and should not be used as a substitute for
the bass and loudness controls on your amplifier or receiver. Adjust the
subwoofer's levels for smoothest low frequency performance. If more bass is
desired, then advance the bass and/or loudness controls on your main
amplifier or receiver.

OPERATING CONTROLS

Power Switch
The power switch must be set into the ON position before the subwoofer
becomes operational. Once it is turned on, the Auto/On/Off circuitry is
engaged. Setting the switch to Off stops all power and functionality of the
subwoofer.The dot symbol on the power switch represents the "ON"
position, the unlabeled side represents the "OFF" position.
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 of your main
speakers. Also see Set-up and Calibration.
Frequency Control
This rotary control adjusts the high frequency roll-off of the subwoofer.
Continuously variable from 40Hz to 120Hz, it is used to precisely match the
subwoofer bass reproduction with that of your main speakers. Also see Set-up
and Calibration.
Phase Control
This rotary control allows fine-tuning in the form of perfect phase matching of
the subwoofer with that of your main speakers. Variable from -180 to 180
degrees, it compensates for the mid-bass acoustic effects of different speaker
locations and listening room effects. Also see Set-up and Calibration.
Video Mode
This switch allows a quick and simple way of boosting the deep bass
characteristics of your subwoofer by adding approximately 3 db in the
40Hz range.
