specification:

Product size: length 18.5cm high 9cm thick 1.2cm AS1424 music spectrum display (professional monitoring level spectrum),using a 32-bit high-speed processor, can capture every detail of music and display it. This spectrum ranks are driven by a dedicated chip, and the display effect is dynamic. The real-time performance and accuracy of the frequency spectrum are not achievable by the general frequency spectrum. This spectrum uses a universal USB interface, DC 5V power supply, devices with USB interfaces can provide power to the spectrum, including computers, mobile phone chargers, mobile power supplies, etc.

main feature:

1. Using a 32-bit high-speed processor (the other spectrums on the market are basically 8-bit single-chip microcomputers),the spectrum display is precise, accurate and beautiful, and can be used for frequency point testing; 2. Two signal acquisition methods: MIC (electret microphone) and LIN (line input); 3. With professional-grade pure hardware AGC (automatic gain control) high-level adjustment of peripheral audio processing circuit, (if software AGC is used, the spectrum sensitivity and accuracy will be greatly reduced),so this shop uses professionally adjusted AGC module, both The accuracy and effect of the frequency spectrum are guaranteed, and the volume is too low and does not display, and the volume is turned up and the full screen is displayed. The spectrum display amplitude can also be adjusted by the potentiometer. 4. AS1424 can be used for car music spectrum. Since cars generally don’t have audio output ports, it needs to be broken to connect the spectrum. AS1424 has a built-in highly sensitive MIC (electret microphone) to collect. You only need to plug the power end into the USB interface to use (no The USB interface needs a (12V to 5V) cigarette lighter to USB converter) to avoid the trouble of dismantling the wiring. 5. 3 classic modes, single spectrum, spectrum + peak hold, floating point, with power-down memory; 6, 5 levels of brightness adjustable, wide adjustable range of brightness, brightness value with power-off memory; 7. Level 5 spectrum speed is adjustable, and it can be adjusted according to personal preference; 8. AS1424 has a total of 24 frequency bands (marked with accurate frequency points),each segment has 14 points, a total of 336 Taiwan Everlight high-brightness LEDs in ultra-dense, (luminescence consistency and life are guaranteed) The top 4 rows use red LEDs, which can be accurate Display the high point of the spectrum; 9. It is designed with a fully transparent plexiglass enclosed enclosure, with a length of 18.5 cm and a thickness of only 1.2 cm.
