To exit the test, press the RECORD button (G). 13. Analog I/O check 13.1 When this test option is selecte

28、d, the screen displays FS = 32.0 kHz. Proceed to the following steps: a. AUX INPUT - MASTER OUT check 1) Turn INPUT, AUX control to MAX, connect the audio frequency oscillator outputs to INPUT AUX. 2) Connect the oscilloscope to OUTPUT MASTER. Set the oscillator to sine wave, 1 kHz, 620 mVpp. (Keep

29、this setting through tests in this section.) The oscilloscope should display approx. 8 Vpp waveform. b. MUTE 1) Press the LOCATOR 4/(8) button. 2) The Mute: OFF indication on the upper-right side of the screen changes to Mute: ON. 3) When the waveform on the oscilloscope disappears upon Mute: ON, th

30、e muting circuit is working. c. LINE INPUT - AUX OUTPUT check 1) Turn INPUT, LINE control to MAX, connect the outputs (sine) from the oscillator to INPUT, LINE. 2) Connect the oscilloscope to OUTPUT AUX.

37、 check 1) Connect DIGITAL 1 output from SP-808 to COAXIAL input of the DAT, and DIGITAL 2 output to OPTICAL input of the DAT. Provide means to monitor DAT digital input signals. 2) Connect the headphones to the DAT. 3) Verify that the DAT is reproducing CD sounds. Also check DAT DIGITAL inputs by to

38、ggling between COAXIAL and OPTICAL. To exit the test, press the RECORD button (G). 15. Initialize If the system parameters in the flash memory are destroyed or the parameters are to be returned to the factory settings, follow the procedure described below. When the initialize screen is selected, pre

39、ss UNDO/REDO button. The system parameters such as system common, system MIDI and system beam controller are initialized. To exit the test, press the RECORD button (G). Exiting the test mode Simply turn off the SP-808. If the flash memory (IC9 of the main board) becomes failure either in terms of so

40、ftware or hardware, the following message appears on the screen. When this message appears, proceed to the following version upgrading procedure. If the contents of the flash memory are not restored, replace the memory with new one; the same message will appear. Retry the version upgrading procedure
