7.Z.WAV Sound Module MPU-401 Header - J11

J11 is a 26-pin, dual-row, 0.100" spaced header the provides connections for an Antex Z.WAV Sound Module. The interface to the Z.WAV via this connector is Roland MPU-401 compati- ble.

8.Z.WAV Sound Module DSP Header - J12

J12 is a 6-pin, dual-row, 0.100" spaced header that provides a connection for digital audio data from an Antex Z.WAV Sound Module to the Z1/Z1e DSP.

9. C52 DSP Emulation Header - J13

J13 is a 14-pin, dual-row, 0.100" spaced header provided for connecting a T.I. XDS510 emulator used for debugging DSP software.

10. C31 DSP Emulation Header - J14

J14 is a 12-pin, dual-row, 0.100" spaced header provided for connecting a T.I. XDS500 or XDS1000 emulators used for de- bugging DSP software.

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 ADAPTER INSTALLATION JUMPER SETTINGSMINIMUM HARDWARE RECOMMENDED Figure 3.
