Detailed Product Description: | The Zhengzhou store audio stores store audio Monopoly Jiaming Yang 1300 +75250 +65 1399 +229 +631 Zheng * City Milan sun technology market, Unit 2, Building 5, 208 sound engineering debugging is generally divided into system debugging and sound debugging, here introduces system debugging steps. The following is a common system steps: 1, line check: in accordance with the drawings, carefully check the line connection, confirm that there is no problem. 2, the initial state of the device settings, set the amplifier input to a minimum, all input and output peripherals knob is set to 0 db or the middle position. Order in accordance with the former level after level power (not open first amplifier), check all equipment is energized normal powering up the amplifier. 3, the initial check system status: appropriate to open a large amplifier gain control, CD into a familiar music, adjust the mixer input level to the basic normal position. Slowly push up a little mixer fader listen to the speaker's voices is normal, is distorted, immediately turn off your mobile phone to check if it is not normal. 4 Frequency adjustment: pink noise generator on the mixer input channels, adjust the level to the normal position, phase meter test microphone placed in the middle of the venue.
