Home Theatre Settings
Set the VOLUME (LINE or SPEAKER) control initially to
the 9 o’clock position.
Set the LOW-PASS FILTER switch to OUT.
Set the EQ switch initially to position A.
Set the PHASE switch initially to 0°.
Set the LOW-PASS FREQ (frequency) control to 140 if
the speaker level inputs are used. The setting is
irrelevant if the line level inputs are used.
See the “Fine Tuning” section for more.

All Applications
The BASS EXTENSION switch offers three options of
subwoofer bass extension. Position A gives the
greatest extension and position C gives the least
extension. Position B provides a compromise setting.
If the system is to be used at very high volume levels
or in a large listening room, restricting the bass
extension by selecting either B or C may help ensure
that the subwoofer is not asked to exceed its
performance limits. In most situations the BASS
EXTENSION switch should be left in position A.
The EQ switch alters the subwoofer bass roll-off
alignment. The bass you hear is a combination of the
subwoofer plus the effects of the room and you should
choose the position that best complements your room
and the location of the subwoofer. Position A gives a
“drier” alignment, more suited to placing the
subwoofer in a corner or compensating for a resonant
room. Position B is suited to a less resonant room
acoustic and use away from a corner.
If you get problems with uneven bass – certain bass
notes are exaggerated more than others – then you
probably have a room interface problem and it is worth
experimenting with the location of the subwoofer.
What may seem like small changes in position – 15cm
(6in) or so – can have a profound effect on the sound.
The use of multiple subwoofers can smooth the
effects of room resonances, as each subwoofer will
tend to excite resonances at different frequencies. If
you appreciably alter the relative distances from the
subwoofer(s) and satellite speakers to the listening
position, re-assess the PHASE switch setting. You
should also check the volume of the subwoofer (using
either the processor output levels or the VOLUME
control on the subwoofer amplifier as appropriate), but
only after setting the phase correctly
