10 Sound Manager
OVERVIEW
The Apple Sound Manager is a standard Mac OS 9
System Extension that provides stereo sound
capabilities on your Power Macintosh.
The PCI-424 system ships with a Sound Manager
driver for the PCI-424 audio card. This driver
allows your Power Macintosh to use any pair of
inputs and outputs (analog or digital) on your
PCI-424 system.

USING 3RD PARTY AUDIO SOFTWARE
Just about every dedicated audio application for
Macintosh supports Sound Manager, along with
many other applications, like video editing
software, that handle audio in one form or another.
Once you’ve installed and configured the MOTU
PCI Sound Manager driver as described in this
chapter, you’ll be able to use any pair of 2408mk3
inputs and outputs (analog or digital) to record
and play back audio from any Sound Manager
compatible program.
SOUND MANAGER IS STEREO ONLY
Sound Manager currently only supports stereo
input and output. Therefore, Sound Manager
compatible programs can only record two channels
at a time with your PCI-424 hardware. Similarly,
they can play back audio through one stereo output
pair on a PCI-424 audio interface, although most
multi-track audio applications can internally mix
more than two tracks to stereo. Consult your
software’s documentation for details.
44.1 AND 48 KHZ ONLY
Sound Manager supports sample rates up to
48 kHz, but nothing higher, so be sure to set the
PCI-424 system sample rate to 44.1 or 48 kHz.
INSTALLING THE PCI SOUND MANAGER
DRIVER
The MOTU PCI Sound Manager Driver is a
standard Macintosh System Extension. When
properly installed, it resides in the Extensions
Folder of the System Folder on your computer’s
startup disk.
