5. Filter Mode – This switch allows for the selection of either Filter On
or Filter Off. (Please see the connections section for suggestions on
which mode is appropriate for your installation).
Rear Panel
6. Power Mode – This switch
can be set to either On, Off or
Auto. If the switch is in the Off
position, the subwoofer will not
power up. If the switch is in the
On position, it will constantly
remain on. If the switch is set to
the Auto position, when a signal
is present the subwoofer will turn
on and will automatically turn off
several minutes after a signal is no
longer present.
7. Sub In – This input is an RCA type mono input.
8. High-Level Input – These are 5-way binding post type speaker con-
nectors. The High-Level inputs are designed to be used on receivers
or amplifi ers that do not incorporate any RCA type subwoofer outputs.
If your receiver is equipped with an RCA type subwoofer output, these
speaker level inputs should not be utilized.
CONNECTING YOUR
MIRAGE SUBWOOFER
CAUTION: All power should be turned off to your system before
any connections are made. Careful attention should be taken to
ensure that all electronic components are not connected to an
AC source. Not doing so could result in potential damage to the
system.
There are two mutually exclusive methods to connect your subwoofer to
your receiver:
Method 1 – RCA – For Home Theater or LFE Applications
1. On the rear of the receiver there should be a single RCA type jack
marked "Subwoofer Out". Connect a single RCA cable from that jack to
the RCA Sub In (#7) on the rear of the subwoofer. A standard male to
male RCA cable is needed.
2. After connecting the single low level Sub In (#7) connection, plug your
MIRAGE subwoofer into an AC outlet. Do not use the AC outlet on the
rear of your receiver.
3. Select either the Filter Mode On or Off (#5). The Filter Mode On
switch position should be used when connecting your MIRAGE subwoof-
er 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 Filter Mode Off 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 Level Control (#1) will still be required.
4. Ensure that the supplied vibration dampeners are installed in the
high-level speaker inputs, as this ensures that the inputs will not vibrate
audibly.
5. See Final System Adjustments, below.
Method 2 – Speaker Level – For Music Applications
1. The other way to connect your subwoofer to your receiver is using a
High-Level (#8) (speaker wire) connection. First remove the highlevel
vibration dampeners that are installed between the terminals and then
simply connect the speaker wires from the Front Left and Right Speaker
Outputs on your receiver to the Left and Right Inputs on the rear 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 (#8) (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 (#7) and High-Level (#8) connections
simultaneously, as this will damage your MIRAGE subwoofer.
FINAL SYSTEM ADJUSTMENTS
1. The Subwoofer is equipped with a master power switch which must be engaged
prior to use. After having completed the break-in process, select the correct position
for the Power Mode switch (#6), 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.
2. Adjust the Level Control (#1) 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 Frequency Setting (#3) on your MIRAGE Speakers subwoofer so
that the frequency range of the subwoofer blends well with that of the front speak-
ers (For use with all settings, except when in Filter Mode Off). 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 95Hz to
120Hz, for the bookshelf speakers 65Hz to 95Hz and for the large crossover
fl oorstanding speakers 40Hz to 65Hz.
4. Adjust the Phase control (#4) so that the subwoofer integrates fully with the rest of
your audio system. This control is adjustable to either 0 degrees or 180 degrees, 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 char-
acteristics 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 fi ne tune your system. Ensuring
the proper blending between the speakers and the subwoofer is critical to the perfor-
mance of your system, as a whole.
