Description:Note:This is DIY Kits,you need do it yourself! thank you!Special statement:For some users that the level of light sensitivity, please complete the user welding test the first thing must press the button for 10 seconds to restore a factory settings!The page picture is very clear! Because the program burned into the chip is not in the initial working state, you must restore the factory settings after the level lights are in normal working condition! . .Sensitivity of the user feel the problem is to restore their own factory settings! . . As long as done this operation, there will be no sensitivity problems, and the level of light sensitivity than we imagined much better! In particular, the signal automatic gain control range is very wide!The data will be saved automatically every 5 seconds after the setting is changed. The data will be extinguished all the time when the data is saved, and the data will be saved several times because the factory data will be saved for the first time. Power or make other settings and operations! If the power is changed immediately after the change, the changed data will not be saved. Please know!Ultra-small size stereo level lights, light bar can be adjusted to rise, the rate of decline and peak lamp residence time, the rate of decline. Each lamp set up a separate current limiting resistor, Ensure the same brightness of the different color lights ,Signal input through the op-amp isolation,Avoid single-chip high frequency interference AUDIOFeatures:1. The minimum volume, PCB the size of 80 * 14mm LED module area : 58 * 14mm2. The feature-rich, user can freely adjust each light bar and the main peak of the real speed of light, with the most suitable for their own display3. Audio input through the TI original signal isolation, the maximum to avoid the single-chip high-frequency interference to an audio circuit in series4. different colors of light alone provided a current limiting resistor. Guarantee a perfect match.Important note:1. MCU in the sampling time-sampling, so that there is dual-channel simultaneous parallel input signal changes fast, the amplitude of the two light bar display may vary, this is a normal situation.2. In extreme cases, there may be very slight high frequency noise. Recommended to replace the signal input line head position as dual-core shielded cable.3. Operating voltage: 7-12v current can work in more than 100MA. Prohibited or voltage exceeds 12v positive and negative reversed, whether the person will cause light damage levelDisplay effect:1. strip show+ after peak travel whereabouts2. strip show after+ the disappearance of the peak travel3. The strip display + (no peak display)4. The strip display + (One lights)5. The strip display + (Two lights)Setting mode:1. Brightness adjustment mode: There are three brightness adjustments, short press to set2. Speed adjustment mode: There are 6-speed adjustment mode, short press to enter adjustment (not recommended to change the default value)Operating Voltage: 7v-12v 100MAColors: 7 Green + 2 orange + 3 redThis level lamp Have standard display mode and Wide range of automatic gain control(AGC)Mode
