external speakers, connect one end of an audio cable (sold separately) to the Audio input jack
(3) and the other end to the Line Out jack on the media player/computer.
NOTE: Before connecting to the AUDIO port on the display, verify what type of Audio Out
connection is available on the media player/computer sound card. The Line Out on a media
player/computer is used to connect to speakers, including a built-in amplifier (AMP). For
additional instructions, refer to the sound card manual.
If the Audio Out on the media player/computer sound card has only Speaker Out, reduce the
media player/computer volume before connecting to the AUDIO port on the display.
If the Audio Out on the media player/computer sound card supports both Speaker Out and Line
Out, choose Line Out.
