1, using specifically designed for audio level tests designed to import integrated circuit chip containing the square root of the dynamic index compression circuit ( Example : Enter 1V, the 1V; enter 4V, the 2V; Input 9V, the 3V), taking into account the dynamics and precision instruction pointer swing moderate, avoiding the pointer does not move the small signal , large signal pointer backing of the state.
 
2, no separate power supply, the power supply can be drawn directly from the original , compared with TA7318P/TA7332P, reducing the cost of a transformer , because occupy space inside the chassis while halving the installation more convenient and flexible.
 
3 , the circuit designed, has the following characteristics :
 
 Enter retrofitting low-pass filter circuit filter out high frequency interference, power supply for harsh environments ( such as car audio systems ) .
 Output adjustable sensitivity for a variety of specifications header.
 The most common 12VDC power supply , convenient to use in the automotive and PC computers.
 has reverse polarity protection.
 There is energized pointer protection function to avoid bottoming boot pointer to extend the life of the header .
use 0.5W metal film resistors, large power margin to ensure reliable and stable long hours of work .
 
 
 
 
[ Technical parameters ]
 
 [ Input Sensitivity ] : 400Hz input audio signal with Fluke 8025B digital multimeter to measure AC mV file , the input : 97mV, 39 level meter pointer to +3 dB position.
 [ Supply voltage ]: DC 12V 0.12A.
 [PCB size ]: 5.2cm × 6.3cm.
 [ Backlight power supply terminal ] : provides DC10 ~ 12V 50MA. Backlight power for a small light bulb .
 [ Drive VU meter , level meter Sensitivity ] : Recommended 500UA sensitivity, 630 European resistance. At this point the best damping effect , the level meter damping effect of other specifications will vary , you need to make further adjustments.
 
Description : The supply voltage must strictly ensure 12VDC, 12VDC , although more than a short-term job, but a long time will burn protection circuit.
