Setting up
To obtain optimal sound results, it is generally necessary to try out different set-ups.
Since the room conditions have a major effect on sound reproduction, we suggest below
a few useful approaches for positioning your quadral loudspeakers.
Main speakers (front)
Where the speakers are positioned in the listening space has a decisive effect on their
sound. Placing the speakers near the corners of the room will essentially give you loud
bass reproduction but with little outline. On the other hand, speakers positioned well
away from the walls sound precise, but also very bright and thin. The best solution is to
place the speakers with at least 30 cm between their backs and the nearest wall. To avoid
loud wall reflections, the distance from the side walls of the room can even be 50 cm or
more. Bookshelf speaker units sound best on a speaker stand or shelf, with the tweeters
arranged at ear height. The cases should be angled and slightly tilted to achieve this.
Ss far as possible, the speakers should be equidistant from the listening position, while
the distance of the speakers from each other can be rather less than the distance from
the listener.
Front centre speaker
Due to the proliferation of plasma and
LCD TVs, these speakers are no longer
shielded magnetically. This causes colour
and geometrical errors and can occur
on older TVs with picture tubes. Since
it can’t be placed on the TV set, the
center speaker can be set lying down
underneath it. The speaker should be at
least 30 cm from the television, and a
minimum of 20 cm from the floor. Apart
from the above, we recommend angling
the center speaker so that the tweeter is
aimed at the listener in order to enjoy its
full sound potential.
when in operation. To avoid injury, never put hands or arms into sound outlets (bass
reflex tubes). Children and pets, in particular, are at risk from this.
• For safety reasons, we generally forbid the opening of loudspeaker cabinets when in
operation or connected since, as explained in the above paragraph, voltages of up
to 50 volts can be present inside.
• Improper handling of mains voltage can cause fatal injury!
Passive loudspeakers must on no account be connected to the electricity supply!
Speaker terminals may only be connected to the appropriate output terminals of
the amplifier. You should never connect these terminals to the electricity supply
(230 V/115 V) in any way since that will otherwise also immediately destroy the
loudspeaker and all connected products. Avoid fitting plugs to ends of speaker cables
that could even remotely be confused with mains supply plugs.
• Loudspeakers that are not magnetically shielded can affect the colour of the TV picture
or cause distortion. A distance of 50 cm is generally sufficient to avoid problems of
this kind. Avoid placing items such as credit cards, diskettes, audio or video cassettes
or other magnetic media on the loudspeaker. This could destroy the information stored
on them. Similarly, avoid operating magnetic tape devices in the immediate vicinity.
