Debug method:
1.Hand in hand of onference system or conference MIC, Connect as shown above, turn down the host output volume, host output to power amplifier or mixer, and open of microphone, you'll need to open of each microphone volume to the appropriate location.
2.The panel of feedback switch plays to pass-through state, adjust the main output volume knob,
when the system just in noise condition, press the feedback switch, and press the calibration switch
again, and then continue to adjust the main output knob, the output of the receiver to get satisfactory sound pressure.
3.Depending on the different microphone, if in the process of debugging, high-pitched sound too
high or heaving, may through the rear panel of tone knobs to correspond attenuation or promotion, microphone sound to achieve satisfactory effect.
Debug method :
1.In the case of single conference MIC more than 5 pcs, using mixer input, from mixer AUX output to the feedback inhibition system, as shown in the above. Through mixer AUX potentiometer to control each channel of micro-
phone volume, then put the main output feedback inhibition system to the mixer of 7 channel input, turn off the seventh channel of AUX potentiometer, to use pusher to control all microphone total volume(see chart).
2.The panel of feedback switch plays to pass-through state, adjust the main output volume knob,when the system just in noise condition, press the feedback switch, and press the calibration switch again, and then continue to adjust the main output knob, the output of the receiver to get satisfactory sound pressure.
3.According to the different microphone, if in the process of debugging, high-pitched sound too high or heaving, may through the rear panel of tone knobs to correspond attenuation or promotionor by adjusting the EQ of mixer, the microphone sound to achieve satisfactory results.
