Manufacturer Description


Program has been written into the chip, you can use the installed
Spectrum comprehensive software upgrade, full use of the upgraded products I shop original special algorithm software filtering technology, spectrum of effect has been essentially improved.
1, spectrum display more gentle, no spikes appear, sensitivity and a better sense of rhythm, like the flame spectrum, the visual effect is more beautiful.
2, to improve the low-frequency spectrum other too rich, lack of high-frequency phenomenon, the effect is more dynamic.
MS1608 Our original two-channel stereo using acquisition technology, the hardware is the left and right channels are connected to the microprocessor 2 independent AD, and then after the software processing to generate three-dimensional spectrum of left and right channels fused (other spectrum network While inserting a dual-channel, but basically only use one signal, we all know that the left and right are not the same, this will result in a loss of signal spectrum display blunt, identification methods: 1, to see results, the stereo effect collection better than mono, 2, see the hardware, respectively, left and right channels can be displayed spectrum access, and left and right channels are not together, we must recognize, oh, the effect is not the same)
The latest V3.2 (using only a single-chip STC12C5A60S2 drive, no driver transistors and other chip, simple circuit, making simple) using FFT algorithm, the program through a lot of optimization, the effect is very good, (Taobao other similar spectrum, but it is the use of chip level completed, not completed by FFT, and other well-known TTPlayer on the computer to play the spectrum is done by FFT algorithm, so that effect by the chip level can not be done with the shop MS1608 compared.
