About the item

  • Long-time reliable and Stable Working.--Designed for audio level testing and design of an integrated circuit chip, includes the square root of a dynamic index compression circuit (Example: Input 1V, the 1V; input 4V, the 2V; input 9V, the 3V). Use 0.5W metal film resistors, large power margin to ensure long-time reliable and stable working..
  • Pointer Swing Moderate--Taking into account the dynamic and precision instruction pointer swing moderate, avoiding that the small signal pointer does not move, the large signal pointer backing of the state..
  • More Convenient and Flexible--No independent power supply required, power supply leads directly from the original. Compared with TA7318P / TA7332P, reduce the cost of a transformer, while the chassis inside takes up less space, the installation is more convenient and flexible..
  • Adjustable Output Sensitivity--Enter the installation of a low-pass filter circuit to filter out high requency interference, power supply for harsh environments (such as car audio system). Adjustable output sensitivity, for a variety of specifications header..
  • 12V DC Power Supply-- The most common 12VDC power supply, easy to use on in-vehicle device and PC computers. With power supply reverse polarity protection. Provide energization pointer protection against boot pointer base, extend header life..
Specification: Item Type: VU Meter Driver Board DB Audio Level Meter Input Sensitivity: 400Hz input audio signal with 8025B digital multimeter range measuring AC mV, input: 97mV, 39 level to + 3dB position. Power Supply Voltage: DC12V 0.12A PCB Size: 63x52x20mm / 2.48x2.05x0.79in Backlight Power Supply Terminals: Available DCl0 to 12V 50MA. Power for small bulbs backlighting. Drive VU Meter, Level Meter Sensitivity: Recommended 500uA sensitivity, 630 ohm resistance. At this time damping effect is the best, the other specifications level meter will be different in damping effect, need further adjustments. Description: The supply voltage must be strict to ensure 12VDC, although more than a short-term work, but a long time will burn protection circuit. Instructions: 1. Input Part: Lin, 0, Rin, is an audio signal input terminal for CD audio output connected to the left and to the right channel. Or an output terminal connected to the first input terminal selection stage, the former should not connected to the output stage output or volume potentiometer. 2. Output Part: Two VU Meter side ”+” and "—" terminal as an output, respectively, should be connected to the ”+' and '-” terminal of two level meter. Drivable level meter sensitivity recommendation: DC 100uA to 500uA. Not exceed 1mA. Board 2500ohm blue 3296 series potentiometer can adjust the sensitivity of the two separately header. Clockwise, sensitivity can be improved. LA, LB is the backlight power supply terminals, RA, RB is the other set backlight power supply terminal.
