Product Introduction:

1. The usage method is simple, RCA in RCA out, or XLR in XLR out. The sound source can be an amplifier, mobile phone, computer, etc;
2. Rich usage scenarios, such as home theaters, studios, and esports, bring you "visible music";
3. It cannot be used as a professional testing instrument, it is not a tool. Positioned as a spectrum analyzer for individual music enthusiasts, it enhances the atmosphere of listening to music. Show a beautiful rhythm. In order to achieve a better visual experience, the engineers' software algorithms have been optimized;
4. It is the painstaking work of my team and is willing to bring more joy to music enthusiasts!

The adjustable potentiometer on the back ot the fuselage can adjust the line gain,which is only valid for line input;

Clock ad justment——
1. Enter time display mode (MODE: 9)
2. The vOL-Key selects the position, and the voLt key selects the number;

Menu description:

MODE—— -Display mode selection, starting from 0:

0: Ordinary spectrum, two channels are mixed.
1: On the basis of mode 0, the peak recording point is added to the top, and the acceleration decreases after a delay;
2: The ordinary spectrum is equally divided screen, and the two channels independent display;
3: On the basis of 2, the peak recording point is added, and the acceleration decreases after the delay, similar to mode l;
4: Similar to 2, but thethe base line is the center horizontal line;
5: Similar to 3, but the the base line is the center horizontal line;
6: Similar to 5, but only shows peak points;
7: Waterfall chart with frequency on the x-axis and time on the y-axis;
8: Waveform, binaural mix, x-axis is time. y-axis is amplitude, bottom I row is real-time amplitude;
9: Similar to 8, the base line is the bottom;
10: Similar to 8, the upper and lower two channels are displayed separately;
11: Level indicator, displayed horizontally from the center to the sides;
12: Similar to 11, with added peak point;
13: Clock mode, 2 channel levels are shown at the bottom;

SPEED--Speed setting, 0-4 affects the falling speed of the floating point from slow to fast, the horizontal movementspeed, etc.

DIMMEF—— -Brightness selectior, five levels of brightness from 0 to 4;

GAIN——Gain setting, range: 0-19 The gain is gradually increasec;

SMOOTH—— Smoothin setting, 0: no smoothin; 1: linea r smoothi; 2 quadratic function fitting

LEARN——Noise learning settings, press VOL+ to enter the noise learning mode, and the bottom displayA horizontal line, any sound produced in this process will be sampled as noise and saved. This part of the sound will be filtered out during actual display. After about 30 seconds, the sampling will end and the display will return to normal. and restore GAIN to 0;

DEMO——Demo mode, after a few seconds of each mode demonstration, it will automatically switch to the next mode, "0" is off, "1" is on;

MIC——Whether to turn on the pickup, "0" is off, "1" is on;

AGC- Automatic Gain Control, 0: Disablec; 1: Enablec; AGC can Provide negative feedback of gain to the input terminal according to the magnitude of the display amplitude, the feedback period is about 5s, in order to automatically adjust the display amplitude in the appropriate range;

SLEER—— -Sleep setting; 0: no sleep; 1: mute automatic display clock;

FACTORY1: All parametertrese to factory settings, including noise data.

Option Description:

MODE——Display mode selection, starting from 0 as follows:
0: Normal spectrum, the two channels are mixed, and the frequency is displayed in order from 20Hz to 20KHz;
1: On the basis of mode 0, the peak recording point is added to the top, and the acceleration decreases after a delay;
2: The common frequency spectrum is equally divided up and down, and the upper and lower two channels are displayed separately;
On the basis of 3:2, the peak recording point is added, and the acceleration decreases after the delay, similar to mode 1;
4: Similar to 2, but the reference point is the center horizontal line;
5: Similar to 3, but the reference point is the center horizontal line;
6: Similar to 5, but only the peak point is displayed;
7: Waterfall chart, x-axis is frequency, y-axis is time;
8: Waveform graph, two-channel mixing, the x-axis is time, the y-axis is amplitude, and the bottom 1 is the real-time amplitude;
9: Similar to 8, the base line is the bottom;
10: Similar to 8, the upper and lower two channels are displayed separately;
11: Level indicator, the middle is displayed horizontally to both sides;
12: Similar to 11, with the addition of the peak point;
