BASIC ITEMS FOR SERVICE 3.1 CHECK POINTS Items to be checked. To maintain product quality, confirm the recommended check points show below. No. Procedure 1 Check the audio input signal. 2 Check operations of the volume. 3 Check operations of the DSP Control Check points <XPRS102/122/82/152> The sound should be output normally when inputting the signal to the LINE/MIC, LINE/HI-Z, STEREO MINI of Input terminal. <XPRS1152S/1182S/1152ST/1182ST> The sound should be output normally when inputting the signal to the Input LEFT and RIGHT. <XPRS102/122/82/152> Turning the LEVEL knobs for INPUT 1 to 3 changes the volume of each input signal. Turning the MASTER VOL knob changes the volume of the output signal. <XPRS1152S/1182S/1152ST/1182ST> Turning the LEVEL knobs changes the volume of input signal. <XPRS102/122/82/152> Confirm that the four DSP preset modes (LIVE/MUSIC/SPEECH/ MONITOR) function properly. ・ Check that the display switches between the four DSP modes. ・ Confirm that the four DSP modes are working by changing the sound quality of the audio output. <XPRS1152S/1182S/1152ST/1182ST> Confirm that the three DSP preset modes (Boost/Extended LF/ Normal) function properly. Switch between the three DSP modes with the SW and confirm that each mode is working by observing the change in sound quality of the audio output. XPRS102 3
