Operating the subwoofer using the Sub Out
terminal of a surround amplifier
If your surround amplifier offers you the option of adjusting the volume of the subwoofer via
the bass management facility we recommend that you proceed as follows:
Adjust the subwoofer's volume control switch to the "neutral" position, and the Frequency con-
trol switch to the "maximum" position. Now carry out a volume test on the surround amplifier,
setting the satellites and the subwoofer to identical volume levels.
Please refer to the operating instructions supplied with your surround amplifier for details on
volume adjustment.
As far as possible, leave the bass control of the amplifier's tone control facility set in the
"neutral" position, otherwise unnecessarily strong bass signals will be delivered to the satellite
speakers; whilst the satellites would then be subject to a heavy load from such bass signals,
they are not be able to reproduce them in the form of low-frequency sound. As described in
the above, set the bass volume to the level you require by adjusting the subwoofer's volume
via the amplifier's bass management facility.
Operation of the subwoofer on the LFE Out of a
DTS / DOLBY amplifier
If your DOLBY or DTS amplifier is fitted with an LFE output, some subwoofers offer here a
symmetrical (balanced) and also an unsymmetrical input (cinch/RCA). The frequency adjuster
(Frequency) is not operational when using these inputs since the amplifier defines the fre-
quency range for this channel. The loudness setting is performed as described in the chapter
above.
Notes on maintaining the loudspeaker
It is best to clean your quadral loudspeaker using a dry, soft cloth. Do not use any solvent.
The loudspeaker systems (subwoofers) should only be cleaned if there is heavy soiling (small
amounts of dust are irrelevant acoustically). This should exclusively be performed using a dry,
soft cloth or a brush and only by using very gentle pressure, otherwise there may be a risk
of causing damage.
Fault Reason Remedy
1) No sound a) Cables wrongly connected a) Check that the cables have been
(see also 6) connected as specified in the instruc-
tions
b) System not switched on b) Switch on the system and adjust the
volume to approx. 9 o’clock position
c) Amplifier faulty c) Check electronics for possible
defect
2) The system sounds bass-less a) Wrong polarity of one a) Check cable connections/change
and thin even when the bass channel into the subwoofer polarity of one connection of
control on the amplifier is amplifier at the subwoofer terminal
turned up (exchange red and black)
b) Bass management on b) Configure the bass management as
surround amp incorrectly described in these operating
configured instructions
c) Subwoofer not functioning c) Switch on the subwoofer and check
the cables
d) The sound projection is d) Mount the feet as supplied, or remove
being impeded the objects that are impeding the
sound projection
3) The system sounds distant a) Wrong polarity of a satellite a) Check cable connections/change
and instruments and voices cable connection polarity of one satellite connection
are hard to locate on subwoofer terminal panel
(exchange red and black)
4) System lacks treble a) The room has unlively a) Place woofer and satellites further
acoustics and the speakers away from the walls
are located in room corners (approx. 80 cm clearance)
b) Bass control set too high on b) Set the bass control to neutral
the amplifier (central) position
5) System sounds distorted a) Volume set too high a) Turn volume down
b) See (6) b) See (6)
c) System is faulty c) Please contact your dealer or quadral
6) Only one speaker working a) Cables connected up wrongly a) Check cable connections
b) Speaker or electronics faulty b) Exchange right and left speaker.
If the mute speaker is now on the
other side then it is faulty, otherwise
it is the amplifier
7) The subwoofer often switches The subwoofer´s settings a) Reduce the volume level on the
require adjustment subwoofer (set to 10 o´clock position)
and turn up the subwoofer´s volume
via the amplifier´s bass manage-
ment facility
b) Connect up the subwoofer by
means of its High Level inputs
(s. 1st connection option)
8) The fundamental tone Unfavourable setting of the a) Change the setting of the frequency
(e.g. male voices) is too subwoofer is causing and/or phase control on the
thin despite correct cable suppression in the fundamental subwoofer till tone sounds fuller
