Main features of music spectrum:

1. Music is our flagship spectrum product, using a higher-level 32-bit ARM processor. This spectrum control card can drive 1-4 conventional P4, P5, P6 full-color screens, or a single P2, P2.5 high-density screen ; With rainbow gradient color display, the frequency spectrum display is precise, accurate, and beautiful, and can be used for frequency point testing.

2. Full-infrared remote control is also reserved for key control, and the setting menu interface is displayed with Chinese and English subtitles.

3. 10 colors, 16 modes, up to 160 color mode combinations, with 10 levels of brightness adjustment, adjustable frequency range, settings with power-off memory;

4. Electret microphone MIC and line input two signal collection methods, adopting core technology, the microphone collection effect and line input effect are very good;

5. With professional-grade AGC (automatic gain control),it has a wide audio adaptation range, which not only guarantees the accuracy and effect of the spectrum, but also does not appear when the volume is too small and does not display, and the volume is turned up and full screen display;

6. With automatic mode conversion function, it can be turned on or off by remote control, and the color and mode will be automatically switched after it is turned on.

Instructions for use:

1. Please insert the remote control cable, audio cable, and power cable in order before using with the shell, then plug the power supply into the 110V or 220V AC outlet, and then turn on the power switch;

2. Please place the receiver of the remote control cable in an unobstructed position to facilitate the reception of remote control signals. Please plug in the remote control cable and then turn on the power. If the remote control cable is not plugged in and then turn on the power, it may work abnormally;

3. The music spectrum can collect audio signals through two ways: voice control induction or line input, and voice control can be turned on or off by remote control;

4. When the voice control is turned on, the line input is still valid. If you only use the voice control, you don't need to insert the 3.5mm audio cable; the default gain of the spectrum is H, and the line input generally uses H. In order to improve the sensitivity of the voice control, you can set the gain to H or put the frequency spectrum close to the speaker;

5. The spectrum line input can only be connected to low-level pre-level signals, such as the line output port of a computer, mobile phone, CD player, decoder, digital broadcast or power amplifier, and cannot be connected to the speaker line port of the power amplifier. If it must be connected to the power of the power amplifier Please use a high-to-low attenuator to attenuate the strong signal before connecting the amplifier output.

6. The frequency spectrum distribution is a 3.5mm headphone plug audio cable. If your device has a lotus interface, please purchase an adapter cable;

7. If one end of the 3.5mm audio cable has been inserted into the audio input jack and the other end is suspended, it is normal for the frequency spectrum to be slightly bounced at this time. At this time, the suspended audio cable is equivalent to an antenna and will induce surrounding electromagnetic signals. The solution is to The audio cable can be connected to the audio device with the dangling end of the audio cable. If the audio cable is not inserted all the way or the contact is not good, there will be bounces, please check and eliminate it.

8. The infrared remote control of this product is equipped with batteries and is not suitable for air transportation. Foreign customers are requested to purchase CR2025 3V button batteries by themselves;
