2、he DSP turns off and the phantom power turns on. 1. Phantom Power Test Use UV-meter to test the MIC sockets pin 1 and pin 2 of each channel from CH1 to CH9/10 respectively. The voltage between pin1 and pin3 is 48V+/-3V .Turn down the 48V switch after finished testing. 2. Signal Input and Output Test

3、 a). The AP setting is as follows: b). The Range Test of Each Output Channel: Input -40dBu, 1 kHz signal to MIC socket of CH1, the output range level of each output channel is as follows: AUX2 OUT: 6dBu (3dBu) THD+N : 0.3% MONITOR OUT: -5dBu (3dBu) THD+N0.3% MAIN OUT LEFT: 0dBu (3dBu) THD+N : 0.3% M

4、AIN OUT RIGHT: 0dBu (3dBu) THD+N : 0.3% HEAD PHONE OUT: 4dBu (3dBu) THD+N : 0.3% TAPE LEFT OUT: -3dBu (3dBu) THD+N : 0.3%. TAPE RIGHT OUT: -4dBu (3dBu) THD+N : 0.3%. c). The Input Sensitivity Test of Each Channel Thereinafter is the corresponding input sensitivity of each input channel when the MAIN

5、 7. TEST PROCEDURE - 21 - OUT is equal to 0dBu and THD+N : 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. (Amplitude value) APM80.1500: 68V. (Amplitude value) 3. AMPLIFIER MODE is in the brid

6、ge status, at that time, the load is 8 ohms. APM80.1000: 108V. (Amplitude value) APM80.1500: 128V. (Amplitude value) 9. Signal Noise Test: a). Turn all the LEVEL GAIN to the minimum, and turn the GAIN of the MAIN and MONITOR knobs to the maximum, at this point, the curve of the amplifier output (LEF

7、T, RIGHT) is as follows: - 25 - 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 - The signal noise is requested to be lower than -65dBu. 10. Listening Test a). Adjust AC voltage, make AC input is

8、 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 (f

9、rom minimum to maximum).During the operation, there should be not occurred big sonic boom, and also doesnt have the noise of turning the potentiometers, the noise of the listening amplifier output and MAIN output can not bigger than the sample. Turn on the PHANTOM power (Note: Before turning on the

10、PHANTOM power, you should turn the MAIN LEVEL and MONITOR LEVEL to the minimum), the noise of the listening amplifier output and MAIN output can not become bigger (refer to the sample). b). Adjust the AC voltage, make the AC output is equal to 115V, the power switch indicates the 115V position, acco
