Apple Workgroup Server 9150/120 - Manual (Page 140)

Recording an alert sound
Although your server can produce stereo sound, the server records alert sounds
in the same way as other Macintosh models: in 8-bit mono sound, at a sample
rate of 22.254 kHz. This makes the alert sounds you record compatible with all
Macintosh computers. For instructions on recording a sound, see the “Sound”
topic of Macintosh Guide, available in the Guide (
h) menu.
Connecting external stereo speakers
You can take advantage of your server’s stereo sound output by connecting
external powered (amplified) speakers.
1 Assemble the speakers and the cable you need.
You need a cable with stereo miniplugs at each end to connect one or both
speakers to the computer. (Some speakers require a dual-plug adapter. Others,
like those shown here, accept a single stereo miniplug and are joined by
standard speaker wires.)
The following illustration shows the equipment configuration and the
connections for a computer sound system.
