Page 4: Introduction
INTRODUCTION The Series 2 and 3 Digital Audio Adapters are IBM AT compatible add-on boards which convert high fidelity analog signals to digital data for storage to, and retrieval from, disk. The Series 2 and 3 adapters sample two channels of audio from 7.35 kHz to 50kHz with 16 bit resolution. - Page 5 In essence, digital audio is a technological process whereby an analog audio signal (produced when sound waves in the air excite a microphone) is first converted into a continuous stream of num- bers (or digits). Once in digital form, the signal is extremely im- mune to degradation caused by system noise or defects in the storage or transmission medium (unlike previous analog sys- tems).

Page 6: Figure 1. Analog-To-Digital Conversion
Figure 1. Analog-to-Digital Conversion That's about five billion bits per hour, which is why you'll need at least an 800 Megabyte hard disk to record an hour of compact disk quality music. To visualize the analog-to-digital conversion process, refer to Fig- ure 1. - Page 7 the quantizer generates a continuous "bit stream" which repre- sents the quantized signal. The continuous stream of digital audio information is converted into a digitally modulated signal using a technique known as linear pulse code modulation. Digital-to-analog conversion (used in playback) is the exact oppo- site of the analog-to digital conversion process and is illustrated in Figure 2.

CONNECTIONS There is a five pin internal CD ROM header for connecting a Z1/Z1e to audio output of a CD-ROM. A 50-pin header is pro- vided on the Z1/Z1e for connecting to an internal SCSI CD-ROM. For more information about the configuration of these and other headers located internally on the Z1, Z1e, SX-3, SX-33, SX-33b and SX-33e, refer to the Connector Descriptions, Figures 11 &... -
