VU meter lever meter description:
- .VU meter lever meter dB meter power meter yellow backlight
- Specification:DC 500μA     Weight:21g       small size,stable performance
- Internal DC Resistance:1K (MF47 multimeter);630 ohm (8025B digital meter testing )
- The backlight is incandescent bulb.Working voltage:6~12V AC or DC.

Driver board description:
- Professional VU meter,lever meter,power meter driver board.  
- Lever meter driver board,dynamic compression, multi protection function
- It uses pro-level audio signal amplifier chip.

Three Features:
1.Use import integrated circuit chip for audio level meter testing.
Built-in compressor circuit (Such as:input 1V,output 1V; input 4V,output 2V; input 9V,output 3 V ).
2.You do not need separate power supply,because it can use the original power.Compared with TA7318P/TA7332P,it reduces a transformer and the install is more convenient.
3.Features for circuit design  
- The input installs low pass filter circuit,removing high frequency disturbances,suitable for
vehicle sound system.
- Adjustable output sensitivity,suitable for many meter head.
- 12VDC power supply,easy to use for car audio and PC computer.
- Use 0.5W metal film protection,large power,can work for a long time.

Parameter:
- Input sensitivity:Input 400Hz audio signal.
- 8025B digital meter testing AC mV,input terminal:97mV,39 level meter,the needles points +3dB.
- Power voltage:DC 12V,current is more than 0.2A.
- PCB Dimension:5.2cm×6.3cm
- Backlight power supply terminal:can supply DC10~12V 50MA for small bulb backlighht power.
- Driver VU meter,level meter sensitivity:We recommend 500UA sensitivity,630 ohm internal resistance.

Note:The power supply voltage must be 12VDC. If voltage is more than 12VDC,it can work in short time.The circuit will be damaged for long time operation.You must cut off the power before connecting wires.
