Speakers

The MediaDock uses four Altec Lansing stereo speakers. Two of the speakers output highrange sound, and two speakers output mid-range and bass sounds. The high-range speakers are embedded in the MediaDock handle. The mid-range speakers are situated below the MediaDock handle. The speakers connect to the power amplifier board via a red and black dual speaker cable.

CD-ROM Reader

The sound system contains a standard NEC CDR-250 dual-speed CD-ROM reader. The CD-ROM reader lets the user access data and play audio CDs. It uses an IDE interface and is assigned to the next available drive letter. The CD-ROM reader is compatible with Kodak Multisession Photo CDs and standard audio CDs. CD-ROM specifications include the following.
n 680 MB capacity n 333,000 blocks/disc n 2048 bytes/blocks n 300 kilobytes (KB) per second data transfer rate n Burst transfer rate, PIO mode 2 n 380 milliseconds (ms) access time n 286 KB memory buffer

Cables

The MediaDock ships with four cables. These include the IDE cable, power cable, line out cable, and speaker cable. The IDE cable provides an interface for the CD ROM reader. The CD ROM power cable carries electrical power from the sound board to the CD ROM. The CD ROM line out cable routes audio from the CD ROM through the MediaDock. The dual speaker cable is attached via connectors to the power amplifier board, providing exceptional sound quality.
