input sensitivity for the analog inputs; for adjusting audio input level from
ADAT or S/PDIF sources, we recommend that you use an external mixer.
Balance Slider
Each stereo output pair has a balance slider, 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 "Vol/Bal On," below.
Vol/Bal On
The Vol/Bal On check-boxes allow you to enable or disable
volume/balance control for each wave device, as desired. To enable
volume/balance control for a particular device, check the Vol/Bal On box
below the device's volume slider; to disable volume/balance control, un-
check the box.
You can check or un-check all of the boxes at once by using the Set All and
Clear All buttons at the right side of the page.
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
Volume/balance control is provided so that the 1212 I/O may be used for
playing back system sounds, or used in conjunction with simple wave
applications without a volume control (such as the Windows 95 Media
Player). In these cases, the volume/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.
If you are using the 1212 I/O with an application that already provides
volume control, or if you have an external means of adjusting the playback
volume, then you can get better performance from your PC by disabling
the wave device volume/balance controls.
Sync Settings
Through the standard Windows 95 driver, each of the 1212 I/O's six input
and output pairs appears to the system as an independent wave device.
The digital audio program must start recording or playback on each of
them, one at a time, which (when the Sync Settings are not used) can cause
small offsets between the stereo pairs.
The Sync Settings solve this by creating a group of synchronized input and
output pairs. The 1212 I/O will not start either recording or playback until
