3. Select either the Crossover Mode Active or Bypass (#1). The Crossover
Mode Active switch position should be used when connecting your
MIRAGE
®
subwoofer to a receiver without bass management or when
you wish to manually control the crossover and volume settings (such as
in a music system).
The Crossover Bypass switch position should be used when connecting to
a receiver with bass management (such as in a digital surround sound
movie system). This connection defeats the crossover feature on the
MIRAGE
®
subwoofer, allowing this control to be handled by the receiver.
Adjusting the front panel Volume Control (#3) will still be required.
4. Ensure that the high-level speaker inputs have been securely tightened,
as this ensures that the inputs will not vibrate audibly.
5. See Final System Adjustments, below.
METHOD 2 – STEREO APPLICATIONS
1. On the rear of the receiver/pre-amp there should be stereo (left and
Right) RCA type jacks marked “Left and Right Pre-Amp Outputs”.
Connect a pair of RCA cables from those jacks to the LFE/Left Input and
Right Input (#7) on the bottom of the subwoofer. A standard male to
male RCA cable is needed.
2. After connecting the stereo low level Inputs (#7) connection, plug your
MIRAGE
®
subwoofer into an AC outlet. Do not use the AC outlet on the
rear of your receiver. After plugging in the unit, switch the Main Power to
On.
3. Select the Crossover Mode Active. The Crossover Mode Active switch
position should be used when connecting your MIRAGE
®
subwoofer to a
receiver without bass management or when you wish to manually control
the crossover and volume settings (such as in a music system). Adjusting
the front panel Volume Control (#3) will still be required.
4. When connecting bookshelf/satellite speakers that have limited bass
output you can use the Low Level Outputs on your subwoofer to
eliminate low frequencies from being sent to your small speakers.
Connect the Left and Right Outputs to the left and right inputs on your
stereo amplifier. The Stereo Outputs (#8) are filtered at 80Hz, 6db/octave.
This should provide you with greater system dynamic range.
5. Ensure that the high-level speaker inputs have been securely tightened,
as this ensures that the inputs will not vibrate audibly.
6. See Final System Adjustments, below.
METHOD 3 – SPEAKER LEVEL – FOR MUSIC APPLICATIONS
1. The other way to connect your subwoofer to your receiver is using a
High-Level (#9) (speaker wire) connection, by simply connecting the
speaker wires from the Front Left and Right Speaker Outputs on your
receiver to the Left and Right Inputs on the bottom of the subwoofer
(#8). It is imperative that speaker polarities be maintained, one must
connect the positive and negative wires to the appropriate positive and
negative terminals. Failure to do so will result in an out of phase
connection, severely limiting the amount of bass in your system.
2. After connecting the High-Level (#9) (speaker wire) between your receiver
and subwoofer, ensure no fray wires are touching, as this could cause a
short circuit and damage your electronics. Plug your MIRAGE
®
subwoofer
into an AC outlet. Do not use the AC outlet on the rear of your receiver.
3. See Final System Adjustments, below.
Do NOT connect both RCA and High-Level connections simultaneously, as
this will damage your MIRAGE
®
subwoofer.
FINAL SYSTEM ADJUSTMENTS
1. After having turned on the main power switch and having broken-in the
speaker, select the correct position for the Power Mode switch (#5), either
On or Auto depending on your system. The Auto selection will leave the
unit in a self-sensing mode, such that should the unit sense an audio
signal it will turn itself on and then shut down after several minutes
without signal, while in the On position the subwoofer always remains
on. Should the system not be used for an extensive period of time, it is
recommended that the subwoofer be unplugged from the AC outlet or
the Main Power Switch (#9) be turned to the OFF position.
2. Adjust the Volume Control (#3) on the front panel of your MIRAGE
®
subwoofer so that the volume of your subwoofer matches the overall
system volume. This ensures a smooth transition between the low and
high frequencies of your system.
3. Adjust the LP Filter Setting (#2) on your MIRAGE
®
Speakers subwoofer so
that the frequency range of the subwoofer blends well with that of the
front speakers (For use with all settings, except when in Crossover Mode
Bypass). Setting the crossover too low will create a gap between the
frequency response of the front speakers and that of the subwoofer, while
setting the crossover frequency too high will create a doubling of certain
frequencies, making the music sound boomy. When using small satellite
speakers, the appropriate crossover frequency should be from 90Hz to
150Hz, for the bookshelf speakers 70Hz to 90Hz and for the large
floorstanding speakers 30Hz to 70Hz.
4. Adjust the Phase control (#4) so that the subwoofer integrates fully with
the rest of your audio system. This control is infinitely adjustable and
ensuring that the subwoofer operates in phase with the rest of the
system is critical, as an out of phase subwoofer will either sound like it is
lacking in bass performance or that its timing is off. This setting will be
determined by your listening position, the characteristics of your listening
room and its interaction with your MIRAGE
®
subwoofer. An out of phase
speaker means that the speaker cone is moving inwards when it should
be moving outwards, like the other speakers in your system, causing
cancellations of certain frequencies. By adjusting the phase control, one
can ensure that all speakers move in the proper direction, at the same
time.
5. Steps 2, 3 and 4 might require repeating in order to fine tune your
system. Ensuring the proper blending between the speakers and the
subwoofer is critical to the performance of your system, as a whole.
