Double 12 level modulation function demo video: http://list.youku.com/albumlist/show/id_51313909.html
Special Announcement:
For some users of this level of light sensitivity, please complete the user welding test. You must press the button for 10 seconds before resuming factory Settings!
Page picture is very clear! Since the program burning into the chip is not in the initial working state, the factory setting must be restored after the level indicator is in normal working state! . .
Users feel the sensitivity of the problem is to restore their own factory Settings! . . Once you do this, there will be no sensitivity problems and the level of light sensitivity is much better than we thought! In particular, the signal automatic gain control range is very broad!
Data will be saved automatically every 5 seconds after the Settings change. When the data is saved, the data will always disappear because the factory data will be saved for the first time, so the data will be saved multiple times. Power on or 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 light, can adjust the light bar up, down speed and peak dwell time, down rate. A separate current-limiting resistance is set for each lamp to ensure the same brightness of lights of different colors. Signal input is isolated through op amp to avoid high-frequency interference of single chip with AUDIO
Features:
1. Minimum volume, PCB size 80 * 14mm LED module area: 58 * 14mm
2. With rich functions, users can freely adjust the actual speed of each lamp bar and main light.
3. The audio input is isolated by TI original signal, which maximally avoids the high frequency interference caused by MCU in series to the audio circuit
4. Different colors of light provide a current limiting resistance.
Important Tips:
1. During the sampling time, the single-chip microcomputer makes the dual-channel parallel input signal change rapidly, and the amplitude displayed by the two light bars may be different, which is the normal situation.
2. In extreme cases, very slight high-frequency noise may occur. It is recommended to replace the signal input wire position with a two-core shielded cable.
3. Working voltage: 7-12V current can work above 100MA. If you disable or reverse the positive and negative poles with a voltage over 12V, will you cause light damage levels
Display effect:
1. Strip show whereabouts after travel peak
2. After the strip show travel peak disappears
3. Bar display (no peak display)
4. Right-click to display after the peak traffic disappears
5. Bar display (three lights)
6. Stripe subtitle display peak effect
7. The jump light on the right side of the peak strip display lights up two
Operating voltage: 7V-12V 100MA
Color: 7 green 2 orange 3 red
The level lamp has a standard display mode and a wide range of automatic gain control (AGC) mode
Wiring instructions:
LIN: left input
SGND: Signal input baseline
RIN: Right input
PGND: power supply
12V: positive pole of 12V supply
Note: The power supply should be within 7-12V dc power supply, with the current above 100MA (do not use overvoltage, do not connect the reverse power cord).
