VU Meter Driver Board DB Audio Level Meter for TA7318P DENON
Product desceiption:
Level meter, VU meter, a small table-driven power amplifier boards, circuit designreference Japan's Panasonic and DENON finished machine table head drive circuit, aprofessional audio amplifier chip. Three characteristics: 1, designed for audio level testing and design of an integrated circuit chip imports,includes the square root of a dynamic index compression circuit (Example: Input 1V, the 1V;input 4V, the 2V; input 9V, the 3V), taking into account the dynamic and precisioninstruction pointer swing moderate, avoiding the small signal pointer does not move, thelarge signal pointer backing of the state. 2, no independent power supply, power supply leads directly from the original, as comparedwith TA7318P / TA7332P, reduce the cost of a transformer, while inside the chassis takes upless space because the half, the installation is more convenient and flexible. 3, the circuit designed, has the following characteristics: Enter the installation of a 1ow-pass filter circuit to filter out high frequencyinterference, power supply for harsh environments (such as car audio system). Output sensitivity adjustable, for a variety of specifications header. The most common 12VDC power supply, easy to use in-vehicle device and PC computers. Has a power reverse polarity protection. Have energized pointer protection against boot pointer base, extend header life. Use 0.5W metal film resistors, large power margin to ensure reliable and stable worklong hours. Technical Parameters: [Input Sensitivity]: 400Hz input audio signal with Fluke 8025B digital multimeter rangemeasuring AC mV, the input: 97mV, 39 level meter to + 3dB position.[Power supply voltage]: DC12V 0.12A.[PCB Size]: 5.2cm X 6.3cm.[Backlight power supply terminals]: Available DCl0 to 12V 50MA. Power for small bulbsbacklighting.[Drive VU meter, level meter Sensitivity]: Recommended 500UA sensitivity, 630 Europeanresistance. At this point the best damping effect, the level meter damping effect otherspecifications will be different, the need for further adjustments. Description: The supply voltage must be strict to ensure 12VDC, l2VDC, although more thana short - term work, but a long time will burn protection circuit. Power connection Wiringmust be carried live operation of this man-made damage is not covered by the warrantyfailure. Instruct ions for use: 1, the input section:Lin, 0, Rin, is an audio signal input terminal for CD audio output connected to the leftand to the right channel. Or an output terminal connected to the first input terminalselection stage, the former should not connected to the output stage output or volumepotentiometer. 2, the output section:Two VU Meter side "+" and "-" terminal as an output, respectively, should be connected toTwo level meter the "+' and '-" terminal. Drivable level meter sensitivity recommendation: DC 100 microamps to 500 microamps. Shouldnot exceed 1mA.Board 2 500 European blue 3296 series potentiometer can adjust the sensitivity of the twoseparately header. Clockwise, sensitivity can be improved. LA, LB for the backlight power supply terminals, RA, RB of the other set backlight powersupply terminal. Package:1 x VU Meter Driver Board
