AS1424Music Spectrum Display (Professional Monitoring Spectrum)With a 32-bit high-speed processor, it can capture every detail of the music and display it.The spectrum rows are driven by dedicated chips and display effect is dynamic.The real-time and accuracy of spectrum are not attainable by general spectrum.
AS1424 V2 version adds AGC (automatic gain control) and built-in MIC (electret microphone acquisition), greatly improving performance, and can be used in vehicle music spectrum!(Currently all sold are V2 versions.
This spectrum uses universal USB interface, DC 5V power supply, and devices with USB interface can supply power to the spectrum, including computers, mobile phone chargers, mobile power supply and so on.
1. Using 32-bit high-speed processor (the other spectrum on the market is basically 8-bit single-chip computer), the spectrum display is accurate, accurate and beautiful, and it can be used for frequency point testing.
2. MIC (electret microphone) and LIN (line input) signal acquisition methods;
3. With Professional LevelPure hardwareAGC (Automatic Gain Control)High standardAdjusted Peripheral Audio Processing Circuit,If we use AGC software, the sensitivity and accuracy of spectrum will be greatly reduced. Therefore, we use professional adjustment AGC module, which not only ensures the accuracy and effect of spectrum, but also ensures the accuracy and accuracy of spectrum.Will not appearThe volume is too small to show.When the volume is turned on and the screen is full,The spectrum display amplitude can also be adjusted by a potentiometer.
4.AS1424 can be used in vehicle music spectrum.Since automobiles generally have no audio output port, the connection spectrum needs to be broken, AS1424Built-in high-sensitivity MIC (electret microphone) acquisition, only need to plug the power end into the USB interface can be used (no USB interface needs a USB interface)(12V to 5V)The cigarette lighter is converted to USB converter to avoid the trouble of disconnecting the car wiring.
5. Three classical modes: single spectrum, spectrum + peak holding, floating point, bandPower failureMemory;
Level 6 and 5 brightness can be adjusted, brightness can be adjusted in a wide range, brightness value with power-off memory;
Level 7 and 5 spectrum speed can be adjusted according to personal preferences.
8. AS1424 has 24 frequency bands (marked with accurate frequency points), 14 points in each band, 336 ultra-dense Taiwanese 100 million light-emitting high-brightness LEDs (luminous consistency and life guarantee) at the top.4 elementsUsing red LED, it can accurately display the high points of the spectrum.
9. The transparent PMMA enclosure is designed with a length of 18.5 cm and a thickness of only 1.2 cm.
AGC (Automatic Gain Control)In particular:
This product is adoptedProfessional AGC Modules and High LevelTuning Audio Processing CircuitPure hardware AGC.
The advantage of using AGC: If the volume is too small, it will automatically amplify, the signal is too large, it will automatically reduce the magnification factor, will not appear the situation of large volume on full screen display, so the spectral sensitivity and display effect will be greatly improved. (The AGC test of V2 version video is taken in kind, and it is a 20-100 test of the output volume of ordinary computer.
True spectrum display, to be durable, or pure color is better. This product has been compared by a variety of color experiments, including the use of multi-color LED, often.The more extreme the thing is, the more pure it is. So the final shape of this product is single blue. The following 10 behaviors are monochrome blue and the top 4 behaviors are monochrome red. This not only embodies the purity of monochrome, but also shows the instantaneous highs of notes in red.
Notes on black and white options:
Black appearance atmospheric, internal components can not be seen outside. Dark light transmitter has a slight attenuation effect on LED luminescence, and the spectrum display is soft.
White crystal clear, LED transmittance is good, white PCB has reflective effect can make spectrum display more beautiful than black.
