comes

with

an integrated

controller. These models are

of playing and recording sounds and support SoundBlaster, Adlib, and Microsoft Windows S applications.

The device drivers for the preinstalled audio adapter are on the hard disk. The d

available on Productthe Recovery orCDevice Driver and IBM Enhanced Diagnosticsthat comesCD with the computer.

If you connect an optional device to the audio adapter, follow the instructions prov manufacturer. (Note that device drivers might be required. If necessary, contact th information on these device drivers.)

The following connectors are available on the integrated audio controller:

ŸLine/headphone outport for connecting powered speakers. To hear audio from the adap connect a set of speakers to the Line out port. These speakers must be powered

amplifier. In general, any

powered speakers designed for use

with personal

with the audio subsystem. These speakers are available with a

wide range

of fe

outputs.
