Instructions：

PowerOn——

After the AC socket on the back is
plugged in, press the power switch next to it. If it was turned off by
remote control last time, it needs to be turned on by remote control
once;

Power Off——

The power switch on the back can
completely shut down the device The power button of the remote control
can enter the standby mode, and press it again to start the machine
immediately; If sleep is set to 1, it will automatically standby after
detecting silence for 10s, and automatically release standby if there is
audio input;

Adjustment parameters——

1.Short press the knob to enter the display menu option, long press the knob for 3
seconds to enter the EQ menu option.Remote control see previous page.

2.Rotate the knob to adjust the value；

3.Double-click the knob to close the menu immediately, or you can wait 10 seconds
for the menu to close automatically；

4.Turn the knob to adjust the output gain of the EQ when the menu is not displayed

Music Spectrum Menu

MODE——Display mode selection：

0：Ordinary spectrum, the two channels are mixed；

1：Ordinary spectrum with the peak point at the top;

2：Ordinary spectrum，baseline is the center horizontal ;

3：Waterfall chart, the x-axis is frequency, the y is time, and the color is amplitude

4：Flow chart, the x is time, the y has a fixed size, and the color is the amplitude；

5：Similar to 4, the y-axis is the amplitude, and the bottom line is the amplitude；

6：level bar；

7：level bar with peak point；

COLOR——13 colors option; 11 is gradient color, 12 is magic color; default : 0;

DIMMER——Brightness , 5 levels of brightness from 0 to 4; default value: 1;

GAIN——Gain setting, range: 0-19 gain increases gradually, default value: 5；

MIC——Whether to enable the pickup, 0: off; 1: on; default value: 1；

CDIR——The direction of color change , 0: horizontal, 1: vertical; default : 0；

SPEED———Speed
setting, 0-4 from slow to fast to affect the speed of peak point
falling, the speed of lateral movement, etc.; default value: 3

DEMO——Demonstration mode, each mode automatically switches to the next mode after a few seconds of demonstration；

FACTORY——1:All parameters are restored to defult settings；

AGC——Whether
to enable automatic gain control, 0: off; 1: on; automatic gain control
can provide gain negative feedback to the input terminal according to
the magnitude of the display amplitude, and the feedback cycle is about
5s, so as to automatically adjust the display amplitude to an
appropriate range; default value: 1;

SLEEP——Sleep setting; 0: no sleep; 1: silent automatic standby; default value: 0;

Equalizer menu

AI——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.

AO——Output
Gain，The output amplitude adjustment after data processing , which
affects the output volume and does not affect the sound quality.

PS——PitchShift,
when the value is 0, 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.

EQ adjustment skills：

1.When listening to ordinary music, use
EQ=11 to compensate the bass and treble components lost in music and
electronic circuits, so that the music sounds layered. EQ=12 is suitable
for systems with large bass line loss;

2.When listening to human voice, use
EQ=13, 14, 15 to make the human voice brighter and reduce the
interference of background music；

3.Internet voice data preprocessing,
EQ=15, the processed data can generate less data volume, but has clear
sound quality, suitable for Internet call processingTest benchmark: This
device uses pink noise as the input source.

Notice：

1.Do not connect to a power supply
higher than 240v, otherwise the board may be damaged, please use the
power cord certified by the relevant agency；

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；
