i
LINE IN/SUB IN – These inputs are an RCA type
LFE/stereo/mono input. If you are connecting your
subwoofer to a pre-amp/processor with a LFE or
Subwoofer pre-amp output, connect a single RCA
cable to the LFE/Left input.
o WA PORT – For future use.
p POWER CORD CONNECTOR – Connect the power
cord from your AC outlet to this input. Connecting
your subwoofer to a surge protector or line
conditioner is always recommended. Do not
connect the power cord to the switched or
unswitched outlet of your receiver as this could
damage your subwoofer and receiver.
a AC MAINS – Turn the main power on/off with
the AC MAINS switch
.
s
STATUS INDICATOR – The LED found on the
amplifier panel will illuminate in blue when the
subwoofer is functioning. If the unit is in Auto
mode and is not receiving a signal, the light will
remain off.
CONNECTING YOUR
MIRAGE MX 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.
METHOD 1 – RCA – SUB IN FOR HOME
THEATER OR LFE APPLICATIONS
1 On the rear of the receiver/pre-amp there should
be a single RCA type jack marked “Subwoofer/Pre-
Amp Out”. Connect a single RCA cable from that
jack to the
i
LINE IN/SUB IN on the rear of the
subwoofer. A standard male to male RCA cable is
needed.
2 After connecting the single
i
LINE IN/SUB IN
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 See Final System Adjustments, below.
FINAL SYSTEM
ADJUSTMENTS
1 After having turned on the main power switch and
having broken-in the speaker, select the correct
position for the
e
POWER MODE, 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.
2 Adjust the
r
VOLUME LEVEL of your MIRAGE MX
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
u
LOW-PASS FILTER on your MIRAGE
MX subwoofer so that the frequency range of the
subwoofer blends well with that of the front
speakers. 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 120Hz, for the bookshelf speakers
70Hz to 90Hz and for the large floorstanding
speakers 40Hz to 70Hz. The Bypass 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 MX subwoofer,
allowing this control to be handled by the receiver.
4 Adjust the
t
PHASE CONTROL so that the
subwoofer integrates fully with the rest of your
audio system. This control ensures that the
subwoofer operates in phase with the rest of the
system, 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 MX 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.
