Setting Up Soundmanager Support - Tascam US-428 Owner's Manual

8.4.1 Setting up SoundManager
Support
The Macintosh Sound Manager is a
standard 2-channel software interface
for playing and recording sound on a
Mac. The audio inputs and outputs
(speakers) that are built into any
Macintosh use the Sound Manager
interface, and essentially every Mac
application that uses sound supports it.
This includes not only audio recording
and editing programs, but also games,
video editors, web browsers, MP3
players, and even Macintosh beeps and
system sounds. Even some audio-
oriented program only support Sound
Manager I/O, such as Digidesign's Pro
Tools Free. The Sound Manager input
and output sources are selected by
control panels. The control panels used
are different in MacOS 8.6 and 9.0, and
are explained separately below.
MacOS 9.0
The "Sound" control panel in MacOS 9.0
is used to select Sound Manager inputs
and outputs. With this control panel
active, click on the left of the window
where it says "Output" to display the
possible Sound
devices. On the right, click on "US-428"
to select it as the Sound Manager
output. The US-428 has its own output
volume controls, so the output volume
slider can only be able to mute or
enable sound output.
volume slider to the right or clicking on it
will send a system beep out the US-428
outputs.
When you click "Input" on the left, the
available input devices appear on the
right. Click on "US-428" to select it as
the Sound Manager input device. Below
it are two choices for "Input Source":
either A:B or C:D. You can select either
as the enabled input pair.

Moving the
When an application is using the Sound
Manager inputs, this "Input Source" field
is grayed out, displaying the current
inputs but preventing you from changing
them here. You can still change the
input pair without quitting your program,
however. To do this, bring up the US-
428 control panel and go to the System
tab. You will find a selection there
labeled "Sound Manager Input." Here
you can change the input pair at any
time, even when an audio program is
active. The grayed out "Input Source"
field in the "Sound" control panel "Input"
section will display any input changes
you make.
MacOS 8.6
The "Monitors and Sound" control panel
in MacOS 8.6 has a "Sound" section. It
displays the currently selected Sound
Manager output and lets you select
among several "Built In" input sources. It
cannot be used to select the US-428 as
the Sound Manger input or output.
The "Sound" control panel has a
selection line at the top to let you
choose among "Alert Sound," "Sound
In," "Sound Out,"
windows. (Note: If your "Sound" control
panel does not have all these options,
you should use the alternate "Sound"
control panel found
