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

volume to approx. 9 o’clock position

c) Amplifier faulty

c) Check electronics for possible

4) System lacks treble

a) The room has unlively

a) Place woofer and satellites further

are located in room corners (approx. 80 cm clearance)

b) Bass control set too high on b) Set the bass control to neutral

5) System sounds distorted

a) Volume set too high

a) Turn volume down

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
