Now
select the Settings button.
MIDI
Chorus. Tick
this to enable a chorus effect to be applied when playing MIDI
files with the Extigy, which can add some extra depth/richness to the file
being played. Unticking this will disable this feature. You
might want to test this out before deciding how to set it.
Center
Speaker Volume. This
setting is available when 5.1 Speakers mode is selected. This
slider bar controls the volume level of the Centre channel. Move this
slider to the Up to increase the Centre channels volume level &
vice versa. This volume level is set proportionately to your Volume
level. Many Speaker systems with a Centre speaker include an externally
adjustable volume control for the Centre channel. You should adjust the
Centre volume level until it is equal to that of the other channels.
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
Redirection. 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.
Now click on Start, Settings, Control
Panel & select the Audio Control applet.

Audio Mixing Quality. This sets the
mixing rate to be used during audio playback, with options available being
22.05 kHz, 44.1 kHz & 48 kHz. Ideally you should
leave this set at 48 kHz for best sound quality, though if you are
on a slow CPU, have other USB devices sharing available bandwidth &
are experiencing poor performance or crackling during playback try using a
lower mixing rate – at that 22.05 kHz would be going a bit
extreme though.
Now select the SPDIF tab.
Output Frequency Selection. Depending
on the device you will be connecting the Extigy’s S/PDIF Output to, you
should set the sampling rate to the highest which the device supports –
to ensure best audio quality, e.g. the Inspire 5700 supports 96 kHz.
Adjust this accordingly.
