Conguration and Use
Setting Input Sensitivity
The wide variety of possible source equipment types that can be connected to an
active subwoofer means that it is important to set the input sensitivity appropriately.
Doing so will help ensure that the subwoofer’s volume adjustment range is adequate
and that its input and DSP electronics are driven properly.
If the source equipment has a published specication for output level, begin by
setting the Sub6 input sensitivity to match the specication as shown in this table:
Source Output Level Sub6 Setting
<1.0V +6dB
<2.0V 0dB
<4.0V -6dB
<10V -14dB
The -14dB sensitivity setting should generally be used when the Sub6 is used for
the LFE channel in a home theatre system.
If the source equipment has no published output level specication, begin by setting
the Input Sensitivity to -6dB. If then when in use the Sub6 volume setting is required
to be towards either its maximum or minimum values, adjust the Input Sensitivity
appropriately such that the volume setting is towards the middle of its range.
With the Sub6 subwoofer positioned
in the listening room and connected to
signal cables and mains power it can be
switched on via the mains switch above
the mains input socket on the rear panel.
The Sub6 must be congured
appropriately for the audio system and
main speakers with which it is to be
used. This is achieved via the rotary
controller, display and menu based
interface on the rear panel. Turn the
rotary controller to select conguration
parameters and press the control to
select options and save any changes.
General Tips
Check it out
Try different subwoofer positions and
settings, before you nally choose a
setup.
Note down settings
When looking for the best subwoofer
position in the room, note down the
ideal setting you found for a position.
When moving the subwoofer between
two positions you will be able to set the
subwoofer to the same conguration as
found before.
Vary the listening music
When experimenting to nd the
optimal settings, use a couple of music
tracks with repetitive bass across a
large spectrum. The tracks should be
sufciently different from each other and
each should cover a wide bass-range.
Musical instruments, such as a double-
bass, bass guitar, church organ, etc.
covering a wide spectrum in the bass
region and above, are very suitable as
these depend on accurately balanced
subwoofers and main speakers.
Verify changes
Although in general it is best to make
adjustments in the sequence outlined
below, note that changing one setting
may inuence another. For example,
nding the right setting for phase may
result in having to decrease gain, even if
this was set correctly before.
It is recommended that you double-
check the previous settings before
moving on to the next one. Obtaining
the best integration of the subwoofers
generally involves a considerable amount
of repeated ne-tuning.
Note
If multiple subwoofers are
employed they should be
congured identically.

Sub6 Conguration Menus 1
The Sub6 conguration menu
parameters and their options are
described in the following paragraphs:
• Input sensitivity: Adjusts the input
sensitivity to match the output level
of your pre-amplier or audio-visual
processor.
• Volume: Set to match the volume of
your main speakers so that bass at
your main listening position is neither
too prominent or too quiet. Setting
the subwoofer volume is important in
terms of both overall system balance
and the demands of different types
of programme material.
