Adjustment method:
1.Control of conference MIC or hand in hand conference system, connection well just according to the picture above , turn down the host output volume, and host output to power amplifier or mixer, the microphone all open, you'll need to turn on each microphone volume to the appropriate location.
2.Control feedback switch to play on the panel to direct state, to eliminate the potentiometer to minimum AB area and environmental noise (lights out), adjust the main output volume knob, when the system just in noise condition, press the feedback switch, press the calibration switch again, and then continue to adjust the main output knob, the output of the receiver to get satisfactory sound pressure. And then adjust the AB area and environmental noise elimination potentiometer, the indicator lights up.
3.Depending on the MIC, if in the process of debugging,high-pitched sound too high or heaving bass is insufficient, can through the rear panel high bass tones knob corresponding attenuation or promotion, microphone sound to achieve satisfactory effect.
