<div ><p><b>Feature:</b></p>1. 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).<br>2. Taking into account the dynamic and instruction pointer swing moderate, avoiding that the small signal pointer does not move, the large signal pointer backing of the state.<br>3. No independent power supply required, power supply leads directly from the original.<br>4. 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.<br>5. 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.<br>6. The most common 12VDC power supply, easy to use on in-vehicle device and PC computers.<br>7. With power supply reverse polarity protection. Provide energization pointer protection against boot pointer base, extend header life.<br>8. Use 0.5W metal film resistors, large power margin to ensure long-time reliable and stable working.<p><br></p><p><b>Specification:</b></p><div class="wang-edit-text"><div>Item Type: VU Meter Driver Board DB Audio Level Meter<br>Input Sensitivity: 400Hz input audio signal with 8025B digital multimeter range<br>measuring AC mV, input: 97mV, 39 level to + 3dB position.<br>Power Supply Voltage: DC12V 0.12A<br>PCB Size: 63x52x20mm / 2.48x2.05x0.79in<br>Backlight Power Supply Terminals: Available DCl0 to 12V 50MA. Power for small bulbs<br>backlighting.<br>Drive VU Meter, Level Meter Sensitivity: Recommended 500uA sensitivity, 630 ohm<br>resistance. At this time damping effect is the best, the other specifications level meter will be different in damping effect, need further adjustments.<br>Description: The supply voltage must be strict to ensure 12VDC, although more than<br>a short-term work, but a long time will burn protection circuit.&nbsp;</div><p><br></p><div>Instructions:<br>1. Input Part:<br>Lin, 0, Rin, is an audio signal input terminal for CD audio output connected to the left<br>and to the right channel.
