Amplifier
If the CD-ROM drive includes audio playback controls, it will also include an amplifier.
The amplifier is included to provide just enough power for the use of headphones. The
amplifier doesn’t improve the digital audio sound quality and you can get better quality
by feeding the CD audio through a soundcard on your PC to deskto ps peakers or to a
home stereo system with a built-in amplifier.
Connectors and Jumpers
The jumpers and cable connections on a CD-ROM drive are very similar to those found
on a hard disk drive. CD-ROM drive manufacturers have standardized the location and
use of the jumpers and connectors. The jumpers and connectors are always located at the
back of the CD-ROM drive, as shown in Figure 10-8.
