1.This is an AS1424 music spectrum display with a 32-bit high-speed processor that captures every detail of the music and displays it. This spectrum is driven by a dedicated chip, which shows the dynamic effect and can be used for frequency testing.
2.MIC (electret microphone) and LIN (line input) two kinds of signal acquisition methods
3.With professional-grade pure hardware AGC (automatic gain control) high-level adjustment of the peripheral audio processing circuit, (if the software AGC will greatly reduce the spectrum sensitivity and accuracy),the professional adjustment of the AGC module, which guarantees The accuracy and effect of the spectrum will not appear when the volume is too small to be displayed, and the volume will be displayed on the full screen. The spectrum display amplitude can also be adjusted by the potentiometer.
4.AS1424 can be used for car music spectrum, because the car generally does not have an audio output port, the connection spectrum needs to be broken, AS1424 built-in high-sensitivity MIC (electret microphone) acquisition, only need to plug the power supply into the USB interface can be used (If there is not the USB interface,then it requires a (12V to 5V) cigarette lighter to USB converter),eliminating the need to disassemble the wiring.
5.3 classic modes, single spectrum, spectrum + peak hold, floating point, with power-down memory;
6.5 levels of brightness adjustable, brightness adjustable range, brightness value with power-down memory;
7.The level 5 spectrum speed is adjustable, can be adjusted according to personal preferences;
8.AS1424 a total of 24 frequency bands (marked with accurate frequency points),each paragraph 14 points, a total of 336 Taiwan billion light bright LED, the top 4 lines with red LED, can accurately display the high point of the spectrum.
Function button operation instructions:
M mode switching
▲ brightness plus
▼ brightness reduction
(A total of 5 levels of brightness, brightness value is recommended 2-4).
M (press and hold) + ▲ (short press) spectrum speed plus
M (press and hold) +▼ (short press) spectrum speed reduction
(A total of 5 speeds, speed recommended 3-4).
▲ (long press) LIN (line input) MIC (microphone input) switching
▼ (long press) L (gain low) H (gain high) switching (L is selected by default, H can be selected for MIC sensing input)
Note: The set value will be saved automatically after 30 seconds.
