Connections
All connections should be made with the equipment switched off.
Ensure that positive terminal on the speaker (coloured red) is connected to the positive
output terminal on the amplifier and that negative terminals on the speaker (coloured
black) is connected to the negative output terminal on the amplifier. Incorrect connection
can result in poor imaging and loss of bass. Ask your dealer for advice when selecting
speaker cable.
Fine Tuning
Before fine tuning, make sure that all the connections in the installation are correct and
secure.
Moving the speakers further from the walls will generally reduce the volume of bass.
Space behind the speakers will also help to create an aural impression of depth.
Conversely, moving the speakers closer to the walls will increase the volume of bass.
If the bass seems uneven with frequency this will most probably be due to resonance
modes in the listening room. Even small changes in the position of the speakers or the
listening position can have a profound effect on how these resonances affect the sound.
Try moving the listening position or locating the speakers along a different wall. The
presence and position of large pieces of furniture can also influence resonance modes.
If the central image lacks focus, try moving the speakers closer together or angling them
inward so that they point at a location just in front of the listening position. If the sound is
too bright, increasing the amount of soft furnishing in the room (heavier curtains for
example) may help balance the sound. Conversely, reducing the amount of soft furnishing
may help brighten a dull sound.
Some rooms suffer from "flutter echoes" – echoes that "bounce" between parallel room
boundaries. Flutter echoes can colour the sound of the speakers in the room. Test for
flutter echoes by standing in the middle of the room and clapping your hands. Flutter
echoes can be reduced by placing irregular shaped items or non-reflective surfaces,
bookshelves, rugs or pictures for example, on one of the offending walls or floor. Ensure
that the speaker stands are upright and firm on the floor. Use carpet piercing spikes if
appropriate and adjust them to take up any unevenness.
Running-in Period
The performance of the speaker will change subtly during the initial listening period. The
drive unit suspensions will loosen up during the first hours of use. The time taken for the
speaker to achieve its intended performance will vary. As a guide, allow up to a week of
average use. However, longer run-in periods (as long as a month) have been reported.
Aftercare
The cabinet surfaces usually only require dusting. If you wish to use an aerosol or other
cleaner, spray aerosols onto a 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. Avoid touching the drive units, as damage may result. In order to
avoid the risk of the surface finish cracking, keep the product away from sources of direct
