EElectronic 12V LED Music Spectrum Display Multi-mode DSP Equalizer Level Indicator

Music Spectrum Equalizer is a professional audio analysis device,
which analyzes and displays music spectrum and equalize band effect.
The analysis frequency response covers 20-20KHz, and the analysis resolution is 15 levels.
can display multiple modes,
built-in DSP processor, realize dual 15-band equalization adjustment with±30db, support AGC.

2.Below the display area are the functions in the EQ adjustment state, in order:
VI--Input Gain,Sampling input adjustment inside the DSP, the gain affects the details of the sampling, in the case of no distortion, please try to increase the input gain, so that more data can be collected.
VO--Output Gain,The output amplitude adjustment after data processing , which affects the output volume and does not affect the sound quality.
AGC--Automatic gain control, default is 0: no control, 1-15: gain to output volume setting . The gain reaches the maximum when the sound is muted, and the gain reaches the minimum when a large level is input. The response time is about 1.5S. Effectively protect equipment from damage
PS--PitchShift, when the value is 8, it is the original tone, and it can be adjusted up and down by ±octachord. Male and female voice change, doll voice can be realized with this function
EQ--Equalizer, 10 groups of custom sound effects from 0 to 9, 6 groups of sound effects from 10 to 15. When group 0 to 9 is selected,
15 frequency points on the right can be customized and saved under this group. In group 10-15, the frequency point on the right is the built-in sound effect of the system, which cannot be edited
How to use equalizer: Enter EQ adjustment mode-- Press the EQ adjustment encoder to enter the EQ adjustment state Select adjustment item-- In the adjustment state, press the encoder again to select the adjustment item, select from left to right Adjustment parameters-- Rotate the encoder, reduce the data counterclockwise, increase the data clockwise, the data range is 0-15, when the data is 0, the bottom light is off, and the top light is red, and the corresponding item will flash when the data is 1-15 exception: When adjusting the PS item, when the value is 8, the transposition function will be turned off, and only the 8th light is flashing at this time
