1、Once the settings are changed, the data is automatically saved every 5 seconds. When the data is saved, the data will remain off and the data will be saved multiple times because the factory data will be saved for the first time. Power or other settings and operations! If you change the power immediately after the change, the changed data will not be saved. 2、Ultra-small stereo level light that adjusts the light bar rise, descent speed and lamp stop time. Each lamp is equipped with an independent current limiting resistor to ensure the same brightness of different color lights. The signal input is isolated by the op amp to avoid single-chip high-frequency interference AUDIO. 3、Rich in functions, users can freely adjust the main top of each light bar and actual light speed, which is most suitable for their own display. 4、Audio input is isolated by TI signal to minimize monolithic high frequency interference in series audio circuits. 5、Different colors of light provide separate current limiting resistors. Guarantee perfect match. 1 x Main Unit1 x 20cm Long 0 Interval 5 Pin Cord Item Type:12 Level Stereo IndicatorDisplay Effect: 1. Strip Show+ After Top Travel Whereabouts 2.

Striped Marquee Display + Top Effect 7. Top+ Strip Show Right Jump Lamp Lights Two Bits Whereabouts 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)ModeStatement:The V 1.2 version software adjusts the previous real-time mode to a professional DB mode, which can be installed in professional related equipment for signal monitoring purposes. The audio amplitude range is -40dB to +9dB, which has professional reference significance.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 top 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 AUDIO.The MCU samples at the sampling time, so that the simultaneous input signals of the two channels change rapidly, and the amplitudes of the two light bars may be different, which is normal.In extreme cases, there may be very slight high frequency noise. It is recommended to replace the signal input head position with a two-core shielded cable.Working voltage: 7-12v current can work above 100MA. It is forbidden that the voltage exceeds 12v positive and negative reversal, will it cause damage.
