12V Power Amplifier VU Meter Driver Board DB Audio Level Meter for TA7318P DENON        ONLY VU Meter Driver Board

Description: Features:  1, the use of audio levels designed for testing the import of integrated circuit chip, containing the square root dynamic exponential compression circuit (for example: input 1V, out 1V; input 4V, out 2V; input 9V, out of 3V), both dynamic and accuracy Instructions, pointer swing moderate, to avoid the small signal pointer does not move, large signal pointer rendering the drawbacks. 2, no separate power supply, can be directly derived from the original power, compared with the TA7318P / TA7332P, reducing the cost of a transformer, while occupying the chassis space for half of the installation is also more convenient and flexible. 3, circuit design, has the following characteristics: ◆ input low-pass filter circuit installed to filter out high-frequency interference, suitable for harsh power supply environment (such as car audio system). ◆ Output sensitivity adjustable for a variety of gauge head. ◆ The most commonly used 12VDC power supply, easy to use in-car machine and PC computer. ◆ reverse polarity protection function of the power supply. ◆ Have power pointer protection, to avoid starting pointer primer, to extend the life of the first table. ◆ 0.5W metal film resistors, power margin, to ensure long-term continuous reliable and stable work. [Technical Parameters] [Input sensitivity]: input 400Hz audio signal, Fluke 8025B digital multimeter AC mV file measurement, input: 97mV, 39 level meter pointer +3 dB position. [Power supply voltage]: DC 12V 0.12A. [PCB size]: 5.2 cm x 6.3 cm. [Backlight power supply terminal]: DC10 ~ 12V 50MA is available. For small bulb backlight power supply. [Drive VU Meter, Level Meter Sensitivity]: Recommended 500UA sensitivity, 630 ohms internal resistance. At this time the damping effect is the best, other specifications of the meter damping effect will be different, need to be further adjusted. Note: The supply voltage must be strictly guaranteed 12VDC, although more than 12VDC can work for a short time, but a long time will burn protection circuit. Wiring connection must be carried out, live operation damage caused by such artificial failure is not covered under warranty. [Instructions for use]: 1, the input section: Lin, 0, Rin, is the audio signal input terminal, suitable for the CD audio output in the left, ground, right channel.Or connected to the front-level input terminal selection output terminal, should not be connected to the output terminal of the front or volume potentiometer output. 2, the output section: The two "+" and "-" terminals on the VU Meter side are outputs and should be connected to the "+" and "-" terminals of the two level meters, respectively. Driven level meter sensitivity Recommended: DC 100 μA ~ 500 μA. Can not exceed 1mA. On-board 2 blue 3296 series 500 ohm potentiometers can adjust the sensitivity of the two headers respectively. Clockwise rotation, the sensitivity increased. LA, LB for the backlight power supply terminals, RA, RB for another group of backlight power supply terminals. 3, the power part:   Package Contents 100% Brand New 1 X 12V Power Amplifier VU Meter Driver Board DB Audio Level Meter for TA7318P DENON
