Music Spectrum Equalizer LED Audio Level Indicator Amplifiers Vu Meters for Cars

Description: 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 damagePS--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 functionEQ--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 The main function:》Stereo audio input or MIC pickup》10 modes + single/dual channel display》Built-in clock; 》Speed/Analog Gain/Digital Gain》DSP digital audio processing;》DSP automatic gain control Parameters:》Volt:DC5v/7-18V》Current:0.5A》Frequency Response:20Hz-20KHz》Sensitivity:>-40dB (94dB SPL @1KHz)》Product Size:250*60*25mm L*W*T》Weight:180g》Channel:2ch Stereo》EQ:15 band ±30db》Display Size:200*30mm MODE--Display mode selection,starting from 0:0:Ordinary spectrum with a peak at the top;1:Ordinary spectrum, no peak at the top;2:Waterfall chart with frequency on the x-axis and time on the y-axis;3:Similar to 0, but only shows the peak point;4:Waveform diagram, binaural mixing, x-axis is time, y-axis is amplitude;5:Similar to 1, but the reference point is the central horizontal line;6:Level bar of equal width, from the middle to both sides in case of two channels;7:Width increment level bar;8:Equal width level bar, right to left, 2 up and down in dual channel;9:Clock mode, bottom blue two-channel mix level; GAIN--Gain setting, range: 0-19 , default value: 6;CHANEL--Number of channels, 0: mono, 1: stereo;SPEED--Speed setting, 0-4 from fast to slow affects the speed of floating point falling, horizontal movement speed, etc., default value: 1;MIC--Whether to enable the built-in microphone, 0: off; 1: on;DEFLT--Restore the factory settings, after setting 1, wait for the menu to disappear, and the system will return to the factory default state, and the EQ data will also be cleared at this time; Notice: 1.Do not connect to a power supply exceeding the specified voltage,otherwise the board may be damaged; 2.Do not immerse in water, or use under the condition of humidity higher than 90% 3.Do not use any solvents or liquids to wipe the screen except absolute alcohol; 4.Do not disassemble by yourself. Product failures caused by non-quality problems are not covered; 5.Don't give to children; 6.After the function changes without notice.
