    7. Test Procedure Finished product test procedure 1. Instruments AP tester Double trace oscillometer Voltmeter 2. Functions test a. Input the proper AC power supply, turn on the main power, POWER LED will be illuminated (green). Then switch on PHANTOM power, PHANTOM LED will be illuminated (red), use a voltmeter to test the first pin and second pin of each MIC (MIC 1, MIC 2), the volt of phantom power should be 46V(±2V).
  • Page 44 LEVEL LEDs will turned off, when turn MAIN MIX LEVEL pot clockwise to the maximize, the LEVEL LEDs will be illuminated in sequence. test that whether the relating LED is illuminated when the level of output signal reaches the exactly value as LED shows .
  • Page 45 b. Turn EQ HI &LOW knob to the MAX and the MIN (EQ MID at the middle), test the frequency response, the frequency response curve is shown as follows, please refer to the following figure. Audio Precision 07/21/03 15:54:30 c. Turn EQ MID to the MAX and the MIN (EQ HI &LOW at the middle), test the frequency response, the frequency response curve is shown as follows, please refer to the following figure.
