Notes
3.
Select either the Filter Mode On or Of
f (#5). The Filter Mode On
switch position should be used when connecting your
MIRAGE
®
subwoofer to a r
eceiver without bass management or when you
wish to manually contr
ol the cr
ossover and volume settings (such as
in a music system). The Filter Mode Of
f switch position should be
used when connecting to a r
eceiver with bass management (such
as in a digital surr
ound sound movie system). This connection
defeats the cr
ossover featur
e on the
MIRAGE
® subwoofer
, allowing
this contr
ol to be handled by the r
eceiver
. Adjusting the fr
ont panel
Level Contr
ol (#1) will still be r
equir
ed.
4.
Ensur
e that the supplied vibration dampeners ar
e installed in the
high-level speaker inputs, as this ensur
es 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 r
eceiver is using
a High-Level (#8) (speaker wir
e) connection. First r
emove the high-
level vibration dampeners that ar
e installed between the terminals
and then simply connect the speaker wir
es fr
om the Fr
ont Left and
Right Speaker Outputs on your r
eceiver to the Left and Right Inputs
on the r
ear of the subwoofer (#8). It is imperative that speaker
polarities be maintained, one must connect the positive and negative wir
es to the appr
opriate positive and negative terminals.
Failur
e to do so will r
esult in an out of phase connection, sever
ely
limiting the amount of bass in your system.
2.
After connecting the High-Level (#8) (speaker wir
e) between your
receiver and subwoofer
, ensur
e no fray wir
es ar
e touching, as this
could cause a short cir
cuit and damage your electr
onics. Plug your
MIRAGE
® subwoofer into an AC outlet. Do not use the AC outlet
on the r
ear of your r
eceiver
.
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 S
YSTEM ADJUSTMENTS
1
.
The Subwoofer is equipped with a master power switch which must
be engaged prior to use.
After having completed the br
eak-in
pr
ocess, select the corr
ect 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 tur
n itself on and then shut down after
several minutes without signal, while in the On position the subwoofer always r
emains on. Should the system not be used for
an extensive period of time, it is r
ecommended that the subwoofer
be unplugged fr
om the AC outlet.
2.
Adjust the Level Contr
ol (#1) on the fr
ont panel of your
MIRAGE
®
subwoofer so that the volume of your subwoofer matches the overall system volume. This ensur
es a smooth transition between
the low and high fr
equencies of your system.
3.
Adjust the Fr
equency Setting (#3) on your
MIRAGE
® Speakers
subwoofer so that the fr
equency range of the subwoofer blends
well with that of the fr
ont speakers (For use with all settings, except
when in Filter Mode Of
f). Setting the cr
ossover too low will cr
eate
a gap between the fr
equency r
esponse of the fr
ont speakers and
that of the subwoofer
, while setting the cr
ossover fr
equency too
high will cr
eate a doubling of certain fr
equencies, making the music
sound boomy
. When using small satellite speakers, the appr
opriate
cr
ossover fr
equency should be fr
om 95Hz to 120Hz, for the
bookshelf speakers 65Hz to 95Hz and for the large cr
ossover
floorstanding speakers 40Hz to 65Hz.
4
Adjust the Phase contr
ol (#4) so that the subwoofer integrates fully
with the r
est of your audio system. This contr
ol is adjustable to
either 0 degr
ees or 180 degr
ees, and ensuring that the subwoofer
operates in phase with the r
est 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 of
f. This setting will be
determined by your listening position, the characteristics of your listening r
oom and its interaction with your
MIRAGE
® subwoofer
.
An out of phase speaker means that the speaker cone is moving inwar
ds when it should be moving outwar
ds, like the other
speakers in your system, causing cancellations of certain fr
equencies. By adjusting the phase contr
ol, one can ensur
e that all
speakers move in the pr
oper dir
ection, at the same time.
5.
Steps 2, 3 and 4 might r
equir
e r
epeating in or
der to fine tune your
system. Ensuring the pr
oper blending between the speakers and
the subwoofer is critical to the performance of your system, as a whole.
