Creative SoundBlaster Audigy 2 - Continued

Now select the Advanced tab.

Front Center Volume. This slider bar is available when 5.1/6.1 Speakers mode is selected & 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 the Volume level. Most Speaker systems with a centre speaker include an externally adjustable volume control for the centre channel. Using these 2 controls you should adjust the centre channelís volume level until it is about equal to that of the other channels.

Rear Center Volume. This slider bar is available when 6.1 Speakers mode is selected & controls the volume level of the centre channel. Move this slider to the Up to increase the rear centre channels volume level & vice versa. This volume level is set proportionately to the Volume level. Some Speaker systems with a rear centre speaker include an externally adjustable volume control for the centre channel. Using these 2 controls you should adjust the centre channelís volume level until it is equal to that of the other channels.

Subwoofer Volume. This setting is available when 5.1/6.1 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.

Balance/Fade. By clicking on & dragging the yellow dot around you can adjust intended position of a sound source. This is most useful where your speakers arenít positioned equidistant Ė as described earlier & you wish to apply a greater Left/Right &/or Front/Rear bias to compensate for this. Press the Default button to reset it to this to the default position.

Now click on Start, Settings, Control Panel, select AudioHQ & open Device Controls.

Digital Output Sampling Rate. Depending on the device you will be connecting the Audigy 2ís S/PDIF Output to, you should set the sampling rate to the highest which the device supports to ensure highest fidelity output.

Now select the Decoder tab.

Dolby Digital (AC-3) Decode. Ticking this setting will enable software (CPU) decoding of an AC-3 (Dolby Digital) stream via the Soundcardís Driver. For this feature to work with a Software DVD Decoder you must set the Audio output mode of the software decoder to S/PDIF Output (If itís available that is), this will enable the Audigy Driver to decode/down-mix the AC-3 stream as appropriate for your setup. Should you choose this option 3 further options become available.

  • Enable Dynamic Range Compression. When Ticked this will yield suppressed bass & limit the peak volume level during AC-3 playback. This is of course, of most use should you not wish to disturb others nearby as it effectively softens audio playback. To experience the full, uncompressed audio range available Untick this option, which is recommended should you not be disturbing anyone when you playing such content.

  • Enable Dolby Pro Logic. Dolby Pro Logic is a 4 channel audio format (With a limited frequency response of 100Hz Ė 7kHz for the rear surround channel). Tick this options should you wish to enable the decoding of Dolby Pro Logic sources, which is recommended.

  • Enable Dolby Digital EX. Dolby Digital Surround EX adds an extra surround (rear centre) channel to Dolby Digital. As such it is effectively a 6.1 channel format & thus should you not be connected to a 6.1 Speaker system you can leave this option Unticked without adversely affecting AC-3 decoding capabilities. Should you have a 6.1 system, e.g. Inspire 6.1 6700, then you may Tick this option should you use DVDs which support this format, e.g. Fellowship Of The Ring extended edition, to experience an additional surround channel with such titles.

SPDIF Passthrough. Should you have an external Dolby Digital/DTS decoder available then it would generally be recommended to select this option so that your external hardware decoder can be used for decoding an AC-3/DTS stream, which will also improve system performance as the CPU isnít be required for decoding.

In the Options tab you can select the Audio device to use from the drop-down menu should you have multiple devices installed.

If you are still having problems with your card I suggest visiting Creative's own support site.
