using speakers
Speakers are included with the monitor (select models only), or are sold
separately. For details on connecting stereo speakers to the PC, see the quick
setup poster.
NOTE: Speakers may be passive (no power button and no power cord) or active
(power button or power cord). Your PC supports only active (powered) speaker
systems; the speaker system must have its own power cord.
A stereo speaker set is a left-right, 2-channel speaker system. A multi-channel
audio speaker system is a system with more than two channels, and may include a
subwoofer. For example, 5.1 channels, referred to as a 6-speaker mode, uses two
front speakers (left-right), two rear speakers (left-right), a center speaker, and a
subwoofer.
If your PC has multi-channel audio speaker capacity (select models only), you can
connect four channels for four speakers output or six channels for 5.1 speakers
output.
Connect your speaker system to the PC and then configure the audio software for
sound output. Refer to “connecting a multi-channel speaker system to your pc“ on
page 42.
