M-AUDIO Delta TDIF - Manual (Page 27)

“SP/ANA Ports.” Selecting “S/PDIF” makes the S/PDIF hardware input
the active input. Selecting “Analog” makes the the analog hardware
inputs active. Remember that when S/PDIF is selected as the Input
Audio Source, “S/PDIF In” must be selected as the master clock,
otherwise no signal can be recorded at the S/PDIF input.
“DISABLE CONTROL” CHECKBOX: When running a music program
that utilizes the Delta ASIO drivers, the music program will take control
of some of the Delta Control Panel functions. Checking this checkbox will
“Disable Control of the Monitor Mixer and Patchbay/Router in Audio
Applications,” namely, these ASIO capable applications. Some programs
interpret Direct Monitoring differently, and may result in undesirable
configurations for monitoring.
Emagic’s Logic program, in particular, will switch the Patchbay/Router
into “Monitor Mixer” mode when Logic is switched into record. You may
want to click on this switch when using Logic , thereby disengaging its
control over the Patchbay/Router.
ON THE MAC: The Hardware Settings Page in the Macintosh version of
the Delta Control Panel also contains software switches that allow you to
select which Delta input and output stereo pair will be used by the Sound
Manager, if and when you choose the Delta as the Sound Manager input
and output device. If you go to the Apple menu | Control Panel |Sounds,
and highlight the Delta icon for Sound In and Sound Out, then your
Apple system sounds will be routed to the Delta hardware output that
you have selected here, and Alert Sounds, if you choose to record, will
receive their input from the Delta hardware input that you select here.
You will want to choose the Delta for input and output in the Sound
control panel if your music program does not use ASIO and the Delta
ASIO drivers. If you are using the ASIO drivers (see Mac Software
Installation), then leave the Sound control panel selection to “built-in.”
With the Sound control panel set to built-in, these Sound Manager
settings in the Delta Control Panel will have no effect.
The Sound Manager driver limits you to using only one of the Delta TDIF
stereo input pairs for audio input and only one of the stereo output pairs
for output. These do not need to be matched pairs- you can use inputs
1&2 for Sound In and S/PDIF for Sound Out, for example, or any
combination that you choose. From the Hardware Settings page on the
Mac with the Sound Manager I/O set to “Analog 1&2” for Input and
“Analog 1&2” for Output. Once you have made a selection, go to the File
menu and “Save as Preferences.”
