Click on Start Menu, Programs,
Creative, Sound Blaster Audigy 2 & select Creative
Speaker Settings.

Speaker/Headphone Selection. From the
drop down menu here select the Speaker system you are
connecting to as appropriate (Or the closest available
option), e.g. if you have the Creative Inspire 6.1 6700
Speakers then set this to 6.1 Speakers.
Synchronize with Control Panel. Tick
this option should you wish to synchronize the Speaker/Headphone
selection option with that in Window’s Sounds &
Audio Devices control panel applet. Should you encounter
issues with 3D audio supporting games (generally) resetting
your Speaker/Headphone Selection option then try
toggling this option to see which resolves it occurring.
Speaker Calibrator Selection. Select
the Calibrate button should you wish to use the
Creative wizard to help you further fine tune your speaker
setup, or not.
Digital Output Only. When Ticked
a digital audio signal will be sent via the digital output
jack to be converted by the DAC onboard the receiver you
have connected. This can be beneficial as the receiver may
have better quality DACs than the Audigy 2 does or be
subject to less EMI, which in either case should yield
optimal audio quality.
The Audigy 2 can also, unlike other
non-Creative Soundcards, send a 2, 4 or 5.1 channel signal
(As per the Speaker/Headphone Selection setting)
using the digital output when connected to certain systems,
e.g. Inspire 5700 & MegaWorks 510D, using a 4 pole
mini-jack (Other systems will merely output this signal as
stereo if not supported). As such you may wish to test this
option out should be connected to a Creative speaker system
using the supplied digital cable. On other non-Creative
systems it is only recommended you enable this option
should be using a 2/2.1 system with digital input (Though
again test this option to check which provides better sound
quality). Untick this option if your speaker system
features analog inputs only.
Now select the Bass Management tab.

Subwoofer Volume. This setting is
available when 5.1 Speakers mode is selected. This
slider bar controls the volume level of the Subwoofer. Move
this slider to the Up to increase the volume level
& vice versa. Most Speaker systems with Subwoofers also
include an external volume control for the Subwoofer. I'd
recommend adjusting these levels until the Subwoofer is at
about 1/3 the maximum Volume level, e.g. Set the
external control to 1/3 & set this slider to the maximum
or whatever combination you prefer. Although you may prefer
to set the Higher/Lower depending on your own preferences
for bass output.
Bass Redirect. Tick this
option to enable the redirection of Bass content to a
Subwoofer which requires a separate input, e.g. Videologic
DigiTheatre LC, otherwise you will not be able to get
any Subwoofer output on such systems (Bar that of the LFE
channel in AC-3/DTS & such). On other Speaker systems
you can leave this Unticked without issue (As they
can create their own Subwoofer content using on-board bass
management), though should you have no Subwoofer output
currently then try enabling this to see if it fixes your
problem. It is also recommended that you Untick this
setting during Dolby Digital/DTS playback as that already
contains a LFE channel. This feature can be customized
further using the Crossover Frequency option beneath.
Crossover Frequency. With Bass
Redirect enabled this option becomes available.
Using this slider bar you can adjust the crossover frequency
(10 – 200Hz), beneath which, such low frequencies will be
directed to the Subwoofer. Increasing this value will
result in a stronger bass output from the Subwoofer &
vice versa. NOTE – Be sure to check your subwoofer &
satellites specifications to see what frequencies they can
handle also so that you don’t set this too low or too
high.
Now select the Mixer icon.

Volume. Use the slider bar here to
set the global volume level for Audio output. Move this
slider to Up to increase the global volume level
& vice versa. It is generally recommended that you set
these to 70% or thereabouts if you intend to adjust the Bass/Treble
levels, this will reduce the amount of amplification the
Soundcard can apply to a source, which could cause audio
artefacts at higher levels. Although should you not intend
to be adjust the Bass/Treble levels then you
should be able to increase the volume level to a much
greater level without compromising quality. This setting is
of course affected by the volume level you’ve set your
speakers too, so you may need to adjust the volume level of
your speakers as well.
Bass. This slider bar controls the
level of amplification for perceivable lower range audio
frequencies (20Hz – 250Hz). Move this slider Up to increase
this level & vice versa. Press the arrow
to reset this to the default level.
Treble. This slider bar controls the
level of amplification for perceivable higher range audio
frequencies (6kHz –20kHz). Move this slider Up to increase
this level & vice versa. Press the arrow
to reset this to the default level.
Source.
These sliders can be used to adjust the volume level of
different audio sources, moving a slider Up will increase
the volume level of said source & vice versa.
