Line out
This connector is used to send audio signals from the server to external devices, such
as powered speakers with built-in amplifiers, headphones, multimedia keyboards, or
the audio line-in connector on a stereo system.
Line in
This connector is used to accept audio signals from external devices, such as line
output from a stereo, television, or musical instrument into the server sound system.
Mic
This connector is used to connect a microphone to your server when you want to
record voice or other sounds on the hard disk drive. It might also be used by speech-
recognition software.
MIDI connector
The musical instrument digital interface (MIDI) connector enables your server to
interact with musical instruments and other musical equipment. You might use the
MIDI connector as an interface between your server and a synthesizer to edit and
store sound information for the synthesizer on the server. See “I/O connector
locations” on page 51 for the location of the MIDI connector. The following table shows
the pin-number assignments for the MIDI connector.
Video connector
Your server uses an AGP video adapter located in the AGP slot on the system board.
There is a 15-pin analog video connector located on the rear of the server. See “I/O
connector locations” on page 51 for the location of this connector. The following table
shows the pin-number assignments for the video connector.
