Features 1、25 Segment sound column design, plexiglass length and width design is reasonable, golden ratio, the side is longer than the front, producing a gorgeous and soft visual effect on light refraction 2、KS25 Adds a voice control function, which can be turned on and off by pressing the button, and adopts an independent MIC module, reducing the difficulty of production 3、Having 8 levels of falling speed adjustment function, 8 classic modes, button control, and power down memory. Having 1T single chip microcomputer, high speed signal acquisition and accurate response 4、7 Level gain setting can amplify or reduce the signal, long press the button to set, with left channel,right channel and MIC mode 3 acquisition methods, which is set by the button 5、Using fog like frosted LED, the color is soft and not dazzling, red, yellow, green, blue, orange and pink, and the 6 color combinations determined by multiple experiments 6、The PCB is embedded in plexiglass, the front and rear are the same arc, the appearance and feel are good, and the refraction effect can also be seen in the rear 7、Using white PCB design, white has a good reflection effect on light, which can make the overall color more uniform and gorgeous, rear mounted input and easy to place, without affecting the front visual effect 8、Plexiglass has high density and heavy weight, the 304 stainless steel screw is used as the gravity support of the sound column, and each layer of the nut is fixed to ensure to be level, not tilt or shake Specification Item Type: Music Audio Spectrum Part Material: ABS+PCB Purpose: LED Music spectrum Model: KS25 Maximum Power Per Channel: 25W Key Operations and Instructions: Short Press: Mode Adjustment Long Press for 1 Second: 10 Speed adjustment, the top LED will display (Default value 4,1-10, the brighter the slower) Long Press for 3 Seconds: 7 Level gain adjustment, the blue part at the bottom has a corresponding display; (Default 4) Long Press for 6 Seconds: The channel and voice switch, the pink LED light is always on the left channel (Pink L); the red LED light remains on the right channel (Orange R); the orange LED light is always on voice activation (Voice activation) Status, line input is automatically closed) Add Description: When the 7 level gain is adjusted, the corresponding LED on the upper right will display the default value 4567 for gain amplification 1/2/3 times, 1/2/3 for gain reduction 3/2 times, default value 4 If you do not enter the sound source, it will pulse , Because the power supply ripple you are using is too large, please replace the low ripple 5V DC power supply or use a computer USB or charging Po test; if the audio input is connected to the amplifier output or speaker, please use high to low signal attenuation, change The input voltage of the audio signal is controlled within 5V, which exceeds the damage to the sound column.
