M-AUDIO Dman PCI - Manual (Page 14)

• SoundFusion™ DSound Acceleration. This feature allows the DSP to per-
form many of the audio duties that would otherwise have to be handled by
the host CPU. In other words, it enables audio acceleration. The default
setting is “enabled.”
• Taskbar. Enabling this function places a SoundFusion™ icon on the
Windows taskbar for easy access to the SoundFusion properties page.
The AEC page controls the following setting:
• Acoustic Echo Cancellation. This feature could be used if the DMAN PCI
board is being used as a speakerphone. This is disabled by default (set to
Never).
The MIDI page controls the following setting:
• Maximum Notes. This is the polyphony setting of the built-in synthesizer.
Raising this number will increase the number of simultaneous MIDI notes,
but will decrease the number of simultaneous 3D audio channels. By
default, this is set to the General MIDI standard setting: 24 notes simulta-
neously. 64 notes is the maximum polyphony possible.
The Windows Device Manager
You may find the DMAN PCI driver status in the Windows Device Manager
page of the System Properties dialog box. Open the Device Manager by press-
ing the Windows Start Button and selecting Settings | Control Panel | System |
Device Manager. Once the Device Manager is open, it will display a list of
device “types.” Scroll down through the list until you locate Sound, video and
game controllers. Click on the “+” next to Sound, video and game controllers
to view the installed products within that type. DMAN PCI is of the class
Sound, video and game controllers and should appear in the list if the DMAN
PCI drivers are properly installed. Below is an example view of the Device
Manager device list.
