NEW Z1/Z1E/SX-3/SX-33/SX-33E SAMPLE RATES

The Z1/Z1e boards marked 9000-2319-300x and SX-3/SX-33/SX- 33e 9000-2334-300x boards now support 8 new sample rates which provide greater compatibility with industry standards. The sample rates currently supported are listed below - the new sam- ple rates are in boldface:

48kHz, 44.1kHz, 37.8kHz, 32kHz, 29.4kHz, 25.2kHz, 24kHz, 22.05kHz, 19.2kHz, 18.9kHz, 17.64kHz, 16kHz, 15.12kHz, 14.7kHz, 12.6kHz, 12kHz, 11.025kHz, 9.6kHz, 9.45kHz, 8.82kHz, 8kHz, 7.56kHz, 7.35kHz, 6.3kHz

NOTE: Because of the sample rate changes, the following sample rates are no longer available on the current Z1/SX-3: 50kHz, 33.3kHz, 25kHz, 20kHz, 16.7kHz, 12.5kHz, 10kHz, 8.33kHz

WINDOWS NT & Z1E SCSI IRQ JUMPER

If you are connecting a SCSI CD-ROM to a Z1e board (marked F2319-4 Rev A or B) under Windows NT, use Windows NT driver V0.8e or later. In addition, DO NOT CONNECT the SCSI IRQx jumper as described on pg. 8. Leave the SCSI IRQx jumper open.

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. The digitized audio signal is easily recorded onto a variety of optical or magnetic media, where it can be stored indefinitely without loss. The digitized signal is then reconverted to an analog signal by reversing the digitizing process. In digital audio rec- ord/playback systems, each of these two functions is performed separately. In digital audio signal processing systems where no record/playback function occurs both analog-to-digitaland digital- to-analogconversion processes occur simultaneously. A variety of techniques are possible, but the most common method by which audio signals are processed digitally is known as linear pulse code modulation, or PCM. Lets take a brief look at how PCM works Figure 1. Analog-to-DigitalConversion Page Figure 2. Digital-to-AnalogConversion JUMPER SETTINGS ADAPTER INSTALLATIONMINIMUM HARDWARE RECOMMENDED Figure 3.
