Positioning
As the sub-bass (low frequency) sound produced by the subwoofer is
non-directional it can be positioned almost anywhere in the room,
although it should not be placed too close to the listener. For optimum
performance try the subwoofer in different positions to find the best
place for a boom-free sound.
Connection to AV amplifier / receiver
Connect to the amplifier LFE subwoofer output.
All inputs work simultaneously.
Set the subwoofer frequency on the amplifier / receiver to 80Hz
(refer to the amplifier / receiver manual).
Set the crossover on the XQ60b to 140Hz.
Set the volume on the XQ60b to the 7th dot.
Ensure that the satellites are set to the appropriate configuration in
the amplifier / receiver menu (refer to the speaker manual).
Adjust the subwoofer volume on the AV amplifier / receiver to your
desired level (refer to the amplifier / receiver manual).
Connection to stereo preamp / receiver
Connect to amplifier speaker or preamp or subwoofer output.
Set the crossover to 80Hz for large speakers or higher to match small
speakers. Start with the volume set at the 7th dot. Adjust the volume
to match output to your main speakers.
Trouble Shooting

REMEDY
Check that the subwoofer is plugged into the mains supply and that any switches are on.
Check any fuses (including the plug) or circuit breakers on the mains supply which may
affect the power to the subwoofer.
Ensure that all equipment is switched on.
Contact your dealer for further advice.
Check and adjust the level control.
Check the output sockets on the source equipment are correctly switched and
adjusted to provide sufficient level to drive the subwoofer.
Check that all connections between the subwoofer and the source equipment
are correct and adjust as necessary.
Contact your dealer for further advice.
Check volume levels of subwoofer and amplifier/receiver.
Manual controls
It is possible to manually adjust the set up of the XQ60b instead of
using the amplifier / receiver.
A. Crossover Frequency Control
The crossover frequency control changes the upper cut-off frequency of
the subwoofer. Its effective range is from 40Hz to 140Hz at a rate of
24dB per octave. The frequency control should be adjusted to achieve
the smoothest integration between the main/satellite speakers and the
subwoofer. Clockwise rotation will increase the cut-off frequency and
anti-clockwise rotation will decrease the cut-off frequency.
1. Ideal crossover - flat response.
2. Crossover point set too low - causes dip in combined response.
3. Crossover point set too high - causes hump in combined response.
B. Phase Control
The phase control will normally be set at 0° but more output level can
sometimes be achieved in the 180° position, particularly when the
subwoofer is far away from the satellite speakers.
C. Volume Control
The volume control adjusts the output level of the subwoofer in relation
to the satellite or AV speaker output level. Clockwise rotation to
increase the output level or anti-clockwise to decrease the output level.
Bass Boost (EQ)
The bass boost control is intended to adjust the response of the
subwoofer to compensate for room conditions and user preferences.
Boost is switchable between 0, +6 and +12dB at around 40Hz.
