OASYS PCI
English
Moving the slider to the top of its range provides the maximum output level;
moving it to the bottom of its range will mute the output.
The volume control is only active when the device’s Control Enable button is on. If
your digital audio application provides its own volume controls, then the volume
control provided here may be unnecessary, and you can save some CPU
processing power by disabling it. For more information, please see “Control
Enable” on page 132.
Please note that wave device volume and balance adjustment apply only to output
(playback). You can adjust the input sensitivity of the analog inputs using the
OASYS PCI Audio Settings control panel; for adjusting audio input level from
ADAT or S/PDIF sources, we recommend that you use an external mixer.
Also, note that the volume and balance controls apply only to audio program
outputs; they do not control the output levels of OASYS PCI synths and effects.
Balance knob
Each stereo output pair has a balance knob, which controls the relative output
levels of the left and right channels.
The balance control is active only when the device’s Vol/Bal On box is checked.
For more information, please see “Control Enable,” below.
Control Enable
NOTE:
This parameter only affects the volume and balance controls in the Wave
Device Settings window. It has no affect on volume, balance, or pan controls in
audio/MIDI software.
The Control Enable buttons allow you to enable or disable volume/balance
control for each wave device, as desired. To enable volume/balance control for a
particular device, turn on the Control Enable button below the device’s volume
slider; to disable volume/balance control, turn the button off.
You can turn all of the buttons on or off at once by using the Enable All and
Disable All buttons at the left side of the window.
Volume and balance controls consume CPU resources, and so we recommend that
volume/balance control remain disabled except when needed. For more
information, see below.
When to use volume/balance control
The volume and balance controls are provided for use when playing back system
sounds, or for use with simple wave applications without a volume control (such
as the Windows Media Player). In these cases, the volume and balance controls
will be helpful.
However, they do consume some of the real-time resources of the CPU. When
volume/balance control is enabled for a wave device, every sample passed to the
device gets scaled by the current volume and balance settings.
