  • Page 23: Test Procedure

    2) 4 ohms high power loads 3) DVD player THE SETTING OF APM80.1000&APM80.1500: a) Set all the knobs to the center position; adjust the potentiometers to the 0 position. The PAD switch is springing, the DSP turns off and the phantom power turns on.
  • Page 24 OUT is equal to 0dBu and THD+N : <0.2%. Press the PAD switch for one time when testing; see whether the output range has 20dBu variation. 1. CH1~CH6 MIC Socket:-40dBu (±3dBu). 2. CH7-8, CH9-10 MIC Socket:-37dBu (±3dBu). 3. CH1~CH6 LINE Socket:-20dBu (±3dBu). Note: The AP output is balanced. 4.
  • Page 25 The error of the above test is +/-3dBu, among them the LEFT and RIGHT of CH7-8 and CH9-10 all need to be tested. 4. MAIN 9-BAND EQ TEST Input -40dBu BAL signal form the CH1, adjust the LEVEL and make the MAIN OUT is equal to 0dBu, the AP scan setting is as follows: 1.
  • Page 26 The error of the above test is+/-3dBu, the LEFT and RIGHT all need to be tested. 5: MONITOR 9-BAND EQ TEST: Keep the constant input condition, plug the AP input wire to the MONITOR OUT, then adjust the LEVEL and make The MONITOR OUT is equal to 0dBu. 1.
  • Page 27 1. AMPLIFIER MODE is the MAIN+MAIN status, the outputs of the amplifier are: APM80.1000: >60V. (Amplitude value) APM80.1500: >68V. (Amplitude value) 2. AMPLIFIER MODE is the MAIN+ MONITOR status, the outputs of the amplifier are: APM80.1000: >60V.
  • Page 28 The signal noise is requested to be lower than -40dBu. b). Alter AP input to the MAIN LEFT and RIGHT outputs of the MIXER, the curve is as follows: - 26 -...
  • Page 29 The signal noise is requested to be lower than -65dBu. 10. Listening Test a). Adjust AC voltage, make AC input is equal to 230V; the power supply switch indicates the 230V position. Connect to the high quality cabinets, connect the signal of the DVD player to the input of each channel, adjust the LEVEL MAIN and MONITOR LEVEL to the appropriate volume, operate the switch and knob of each channel respectively (from minimum to maximum).During the operation, there should be not occurred big sonic...
