The EQUILISATION switch alters the subwoofer bass
roll-off alignment appropriate to MOVIE or MUSIC
listening. The MOVIE position gives a “drier” alignment,
more suited to the demands of action movie low
frequency effects. The MUSIC position is suited to a
faster more accurate bass line. The 3.5mm
Equalisation input on the back panel is designed to
receive a 12V signal that will toggle the MOVIE/MUSIC
setting at the front panel. Set appropriately, the 12V
trigger output of a processor can automate ideal
performance of the subwoofer. If the front panel switch
is set for MOVIE, the 12V trigger will change it to
MUSIC. The reverse is also true. Care must be taken
in setup of the processor in order to take advantage of
this feature.
If you get problems with uneven bass – certain bass
notes are exaggerated more than others – then you
probably have a room interface problem and it is worth
experimenting with the location of the subwoofer.
What may seem like small changes in position – 15cm
(6in) or so – can have a profound effect on the sound.
The use of multiple subwoofers can smooth the
effects of room resonances, as each subwoofer will
tend to excite resonances at different frequencies. If
you appreciably alter the relative distances from the
subwoofer(s) and satellite speakers to the listening
position, re-assess the PHASE switch setting. You
should also check the volume of the subwoofer (using
either the processor output levels or the VOLUME
control on the subwoofer amplifier as appropriate), but
only after setting the phase correctly.
Running-in Period
The performance of the speaker will change subtly
during the initial listening period. If the speaker has
been stored in a cold environment, the damping
compounds and suspension materials of the drive
units will take some time to recover their correct
mechanical properties. The drive unit suspensions will
also loosen up during the first hours of use. The time
taken for the speaker to achieve its intended
performance will vary depending on previous storage
conditions and how it is used. As a guide, allow up to
a week for the temperature effects to stabilise and
15 hours of average use for the mechanical parts to
attain their intended design characteristics.
However, longer run-in periods (as long as a month)
have been reported and there is evidence to suggest
that this has little to do with the speaker changing and
more to do with the listener getting used to the new
sound. This is especially so with highly revealing
speakers such as these where there may be a
significant increase in the amount of detail compared
with what the listener has previously been used to; the
sound may at first appear too “up front” and perhaps a
little hard. After an extended period of time the sound
will seem to mellow, but without losing clarity and detail.
Aftercare
The cabinet surfaces usually only require dusting. If
you wish to use an aerosol or other cleaner, remove
the grille first by gently pulling it away from the
cabinet. Spray aerosols onto the cleaning cloth, not
directly onto the product. Test a small area first, as
some cleaning products may damage some of the
surfaces. Avoid products that are abrasive, or contain
acid, alkali or anti-bacterial agents. Do not use
cleaning agents on the drive units. The grille fabric
may be cleaned with a normal clothes brush whilst the
grille is detached from the cabinet.
Do not use the subwoofer as a table. When in use,
objects left on top of the subwoofer are liable to rattle.
In particular, avoid the risk of liquids being spilled (e.g.
from drinks or vases of flowers).
If the system is taken out of use for a long period,
disconnect the subwoofer amplifier from the mains
supply.
