2、: 1). After the surface testing is OK, input proper AC power voltage, open the main power switch, POWER led will light up (green). Then open the PHANTOM switch, the PHANTOM led will light up (red), it has 46V (2V) PHANTOM voltage of the second and third pin on each MIC MIC1, MIC2, MIC3, MIC4, MIC (M

3、ONO) which had been tested by voltmeter. At last, close the switch (Note: we should close this switch, or the instruments will be damaged). 2). Adjust all the TRIM knob to min, the LEVEL, EQ, AUX knob to 0, and the PAN to mid, turn all the keys to OFF. 3). Connect the balanced input to MIC MIC1, MIC

4、2, MIC3, MIC4, MIC (MONO), connect - 18 - the unbalanced input to LINE IN 5/6, rotate the PAN knob of the corresponding channel on LINE IN 7/8 to LEFT or RIGHT, a. The unbalanced output of AUX1, AUX2 which has tested is +2dBu (2dB) THD+N=0.005%; b. Adjust the AUX1, AUX2 knob to min, the unbalanced o

5、utput (LEFT 5). Connect the unbalanced input to AUX RETURN1, the balanced output (LEFT 6). Connect the RCA terminal to L the LED LEVEL indicator will light up in return. The MAIN MIX OUTPUT (LEFT the PEAK led will light up (red). Use the same way to test and see if the corresponding PEAK led of CHAN

6、NEL2CHANNEL4 in normal. 5. Frequency Response Test: Input signal from LINE1, LINE2, LINE3, LINE4, LINE5, LINE6, the output frequency curve on MAIN MIX OUTPUT (LEFT rotate the corresponding channel of EQ LOW to min (-15) in counterclockwise, and the output is -15dBu (2dB); 2). Change the input freque

7、ncy to 2.5KHz, rotate the corresponding channel of EQ MID knob to max (+12) in clockwise, and the output is +12dBu (2dB); rotate the corresponding channel of EQ MID to min, and the output is -12dBu (2dB); 3). Change the input frequency to 12KHz, rotate the corresponding channel of EQ HIGH to max (+1

8、5) in clockwise, and the output is +15dBu (3dB). 6. The effect of DSP: 1). Input signal from MIC1 to MIC4, output signal from MAIN MIX OUTPUT, rotate the AUX RTN2 (DFX) to max in clockwise, rotate the PRESETS and ARATION knob, it will appear the signal which has been processed by DSP, if the INPUT s

9、ignal is larger, the PEAK will light up (red), press the DFX MUTE key, it will appear the BYPASS signal. 2). Input signal from MIC1 to MIC4, output signal from AUX SENDS1, rotate the AUX2 to min, rotate the AUX1, AUX RTN2 (DFX), AUX2/DFX TO AUX1 to max in clockwise, rotate the PRESETS and ARATION kn

10、ob, it will appear the signal which has been processed by DSP, if the INPUT signal is larger, the PEAK led will light up (red), press the DFX MUTE key, it will appear the BYPASS signal. 7. USB Test: 1). Set the MAIN MIX LEVEL, PHONES/CONTROL ROOM, EQ, PAN, BAL knob to 0, the TRIM, AUX1, AUX RTN1, AU

11、X RTN2 (DFX), AUX2/DFX TO AUX1, 2TK IN to min, rotate the PAN on CH1 to LEFT, the PAN knob on CH2 to RIGHT, and turn the entire -21 - keys to OFF. 2). Input 0dBu to AP, connect the balanced input to MIC1, MIC2, rotate the LEVEL on CH1 CH2 to max, and connect the unbalanced output to MAIN MIX OUTPUT,

12、 the output is +10dBu (2dB) THD+N0.005%. 3). Switch the USB RECORD to CH1/2, the USB PLAYBACK to MAIN MIX, and connect the USB line to PC. Open the recorder to tape for 60 seconds: 4). Take off the input signal, and press the playing key, the output is +10dBu (2dB) THD+N0.1%. 5). Input 0dBu to AP, c

13、onnect the balanced input to MIC1, MIC2, rotate the LEVEL on CH1, CH2 to max, the balanced output to MAIN MIX OUTPUT, and the output is +10dBu (2dB) THD+N0.005%. 6). Switch the USB RECORD to MAIN MIX, the USB PLAYBACK ot CH7/8, and connect the USB line to PC. Open the recorder to tape for 60 seconds

14、: 7). Take off the input signal, press the LINE/USB on CH11/12, rotate the CH LEVEL to 0, press the playing key, and the output is +4dBu (2dB) THD+N5%. - 22 - 8). Open the C:ApwinS2A-A FFT. At2 and set as following picture: 9). Do not input signal, connect the unbalanced output to MAIN MIX OUTPUT, s

15、witch the USB RECORD to MAIN MIX, the USB PLAYBACK to MAIN MIX, connect the USB line to PC. Open the recorder to tape for 60 seconds: 10). After recording, press the playing key, the AP will start to scan, the waveform of the picture has not changed much, and connect the high quality amplifier and s

16、peaker to see if it will appear high frequency sounding. - 23 - 8. Selecting Check: connect the AMX-140FX USB to high quality amplifier and speaker, to see if it will appear abnormal noise. 9. Factory Presets: rotate the entire volume control knob to min, the other control knob to mid, and turn the

17、entire switch OFF. - 24 - 8.
