Quadral AURUM VII - Manual (Page 6)

Fault
Audible distortion even at low
volume
No sound
Slender, bright sound.
Sounds distant and
unrealistic.
Bass notes too powerful
Lack of treble
Cause
a) Fault in the electronics
b) Fault in the speaker
a) Cabling incorrect
b) Amplifier switched off
a) Incorrect polarity
b) Unfavourable set-up
a) Unfavourable speaker
set-up (e.g. in the corner
of a room)
b) Bass control on amplifier
set high
a) The tweeters are not
properly aligned
Rectification
a) The fault lies in the
electronics if the problem
affects both speakers.
Swap over the left and
right speakers if only one
speaker is affected. If the
problem is still on the
same channel, your
electronics are faulty.
The speaker is faulty if
the problem is now on
the other channel.
b) Please contact your
dealer or our service
(tel. +49 (0) 511-7904-0).
a) Check the cabling.
b) Switch on the system.
a) Check to see if a terminal
marked with + on the
amplifier has been
inadvertently connected
to a terminal marked
with - on the speaker or
vice versa.
b) Set up the speaker closer
to a wall, but maintain a
minimum clearance of
5 cm between the back
of the speaker and the
wall.
a) Move the speaker further
away from the adjacent
walls.
b) Set the bass control on
your amplifier to a
neutral position.
a) Position the speakers so
that the tweeters are
facing directly towards
your listening position.
