the button for 5 seconds to exit) .
1.1 second
a.The rising speed of the light bar (15 optional)
b.The falling speed of the light bar (15 optional)
c.The holding time of the peak (15 optional)
d.The falling speed of the peak (15 optional)
e.Brightness adjustment (15 optional)
Loop in these functions.
2.Click the button - Loop to change the parameters set.
It has the function of eliminating the influence of environmental noise on product performance ：（In normal mode ,three-click button opens and automatically exits after recognition）
（Special description：Every environment has different environmental noise,Because it’s the microphone that picks up the sound,and the microphone can’t recognize noise or music,So we need to eliminate environmental noise. Then the sound reflected by the level lamp is the real sound of music. Before making this correction,make sure you don’t play music or talk ,the whole process will be completed in 5 seconds,so that the current environmental noise can be recognized.It is suggested that correction should be made once for every change of environment. ）
Sensitivity setting mode:(In normal mode, Four Click to enter,No click 5 seconds to exit.)
1.Single -Click - Sensitivity is reduced(The more lights light on the indicator ,
The sensitivity will getting more lower (30 optional)).
2.Double-Click - Sensitivity increases(The less lights light on the indicator ,The
sensitivity will getting more higher (30 optional)).
(Note: Under different ambient noises, the bottom noise can be removed by adjusting the sensitivity. For example, when the ambient noise is high, can be reduce the sensitivity to achieve the purpose that the ambient noise is not displayed on the lamp bar.)
AGC Speed Mode:(In normal mode, Five Click to enter,No click 5 seconds to exit.)
1.Single -Click - AGC speed reduced (The more lights light on the indicator,The AGC speed will getting more slower(30 optional)).
2.Double-Click - AGC speed increases(The less lights light on the indicator,The AGC speed will getting more faster (30 optional)).
(NOTE:The principle of AGC is to enlarge the input small signal to full screen display, reduce the large signal to the range that the screen can display, and automatically scale the signal according to the size of the input signal.
The speed of the AGC is the speed at which the small signal is amplified to the full screen display. Because the input signal exceeds the display area, it will be compressed immediately. If it is used in an environment where the signal amplitude varies greatly, it is recommended that the AGC speed be adjusted to faster.)
Lighting function: (in normal mode, after clicking once and pressing 1 second to enter and Press 1 second to exit)
1.Single press - lighting brightness increase (Level 15 brightness is optional)
2.Double click - lighting brightness decreases (Level 15 brightness is optional)
